Customer Stories

DSI is a leading industry foundation in the Dutch financial sector, responsible for certification, accreditation, and continuous professional development. Established by and for the sector, DSI sets and upholds the standards for integrity and expertise, helping financial institutions demonstrate compliance with regulation and ensuring that clients and regulators can trust the professionalism of certified advisors.

As expectations around digital engagement and knowledge sharing evolve, DSI set out to transform how it creates, manages, and distributes content, moving from ad hoc article creation to a scalable, structured, and reliable content platform.

‍

The challenge: Unlocking knowledge and scaling content creation

DSI holds over 27 years of disciplinary rulings and domain knowledge, but much of this information is stored in static documents and PDF files, making it difficult to access, reuse, or translate into engaging content.

“At one point, if we wanted to write an article, we relied heavily on internal experts remembering specific cases,” explains Marin Schrijen, Digital Lead at DSI. “That’s not a future proof way of working.”

In addition, content creation remained informal and unstructured. With a small team and no dedicated content department, articles were created with no consistent frequency, often depending on individual initiative rather than a repeatable process. This led to inconsistent tone of voice, and made it harder for the company to respond quickly to relevant topics in the market.

DSI needed a way to turn its knowledge into accessible, scalable, and consistent content, and partnered with CLEVR to achieve exactly that.

‍

The solution: An AI-driven content generation platform

Together with CLEVR, DSI developed an AI-powered content platform built on an agent-based architecture that combines a centralized knowledge base, configurable AI agents, and structured workflows to generate high quality content at scale.

“At CLEVR, we approach AI as a controlled, business-ready capability, not a standalone tool,” says Janet van Zelderen, Customer Success Manager at CLEVR. “Our focus is on grounding AI in enterprise data, orchestrating it through governed workflows, and embedding it into real processes where it creates measurable value. In this case, that means turning DSI’s knowledge into a structured, scalable content engine where quality, consistency, and compliance are built-in by design.”

At the core of the solution is a centralized interface that acts as the control layer of the AI content platform. It orchestrates the interaction between data, models, and workflows, and it enables users to configure, trigger, and manage the full content generation lifecycle, connecting to:

• A centralized knowledge base - A structured repository of all disciplinary cases, publications, and domain knowledge.
• AI agents with defined roles - Configurable “digital journalists” with specific prompts, tone of voice, and responsibilities.
• Agent workflows - Orchestrated sequences where multiple agents collaborate, handling interpretation, writing, validation, and refinement.

A user can enter a prompt or select an external article via the plugin, choose a predefined journalist profile, and finalize with a workflow designed to draft, refine, validate, and structure the output. Within seconds, a high-quality draft is generated, which can be quickly reviewed and published across channels.

“It’s really like working with a team of digital journalists,” says Marin. “You define what they should know, how they should write, and what the output should look like. With this level of control and configuration, we can generate outputs that hardly require any refinements.”

‍

Impact: From ad hoc content to a scalable publishing model

The introduction of the AI platform fundamentally changed how DSI approaches content creation. Where previous articles were published sporadically, DSI can now generate content consistently and at volume, without sacrificing on quality.

“We can now significantly accelerate how we create and publish content,” explains Marin. “By grounding every output in our centralized knowledge base rather than relying on individual expertise or manual effort, we ensure that content is consistently accurate, aligned with our standards, and rooted in validated information.”

The solution demonstrates what effective, enterprise-ready AI looks like in practice. By embedding AI within well-defined, governed workflows and grounding it in the organization’s own data, DSI has moved beyond isolated use cases to a scalable capability that delivers value across the business. As a result, DSI has achieved:

1. Scalable and structured content production
2. Significant time savings in content creation and research
3. More time available for higher-value business activities
4. Consistent tone of voice and content quality
5. Full control over output through defined profiles and workflows
6. Reduced dependency on individual expertise
7. Faster response to industry developments and market topics
8. Reusable knowledge across articles, presentations, and insights

“Because of the way the platform is architected, extending it beyond articles is straightforward,” says Janet. “The same pipelines can be reused to generate presentation decks, briefings, or research summaries by swapping templates and output formats, allowing DSI to scale from content creation to broader knowledge delivery without rebuilding logic, while maintaining governance, traceability, and consistency.”

‍

Collaboration: Building a flexible and future ready foundation

DSI and CLEVR worked together to build lasting capability, laying the groundwork for the promise of the hybrid workforce where people and AI systems operate together in a structured, governed process. Rather than only delivering a solution, both teams worked together to reach the level of maturity required to operationalize AI in a controlled and scalable way.

DSI actively contributed by defining use cases, shaping workflows, and validating outputs, while CLEVR supported the technical foundation and invested significantly in enabling the organization. This included hands-on guidance in prompt design, model selection, and workflow configuration, as well as upskilling teams to work effectively with AI.

“We work closely with CLEVR on an ongoing basis, so we know what to expect, from the collaboration,” says Marin. “They are closely involved throughout the process, helping us define the right prompts, select the appropriate models, and structure the workflows. That continuous support makes it much easier for us to adopt the platform new possibilities and build the confidence to use the platform effectively across the organization."

With the foundation in place, DSI is well positioned to continuously extend the platform, turning it into a central building block for future digital services. Some examples the organization is already exploring are direct website integration via APIs, collaboration with external experts, and the introduction of chatbots and internal AI assistants to support broader knowledge access across the organization.

By transforming fragmented knowledge into a scalable, AI driven content engine, DSI is not only improving how it communicates, but also strengthening its role as a trusted knowledge partner in the financial sector.

And CLEVR continues to support DSI as a strategic partner in this journey.

Digital services, new partnerships, and rising expectations around accessibility and personalization are reshaping how insurers support their members. For Menzis, one of the Netherlands’ largest health insurers, this evolution directly connects to its long‑standing mission of keeping healthcare accessible and relevant for everyone.

Founded in 1836, Menzis is a non‑profit cooperative that places people at the center of everything it does. Working closely with healthcare providers, municipalities, and partners, the organization continuously explores smarter and more sustainable ways to support the health of its 1.9 million members.

To do that effectively in a rapidly evolving market, they needed a trusted partner to help them manage, personalize, and expand its additional services, digital health solutions, and benefits.

‍

The challenge: Limited flexibility in a fast‑moving market

In the Dutch healthcare market, insurers operate in one of the most regulated environments in Europe. Core insurance packages are largely standardized and tightly controlled by legislation, with expectations around digital services to continue to rise.

This means insurers must continuously look for new ways to keep pace with the changing market, deliver high quality service, and introduce digital health solutions that support people throughout their entire health journey.

“Before the Proposition Backend, we were dependent on app releases and therefore indirectly on iOS and Android," says Siona Gidding, Product Owner Digital Partnerships | Care Access & Care Innovation, Menzis Cooperative. "That dependency also applied to content adjustments within the Extras.”

Menzis needed a more flexible setup that would allow the organization to manage and expand its Extras offering with greater speed and independence. The aim was to create an environment that would allow the team to introduce new services, partnerships, and digital health solutions faster, while still providing members with a seamless and consistent experience through the Menzis app.

The solution: A Mendix backend to orchestrate propositions

To address this challenge, CLEVR built Backend Propositions, a Mendix application that acts as a centralized backend layer for managing Menzis Extras.

Instead of embedding commercial logic directly in the consumer app, the platform gives Menzis a flexible environment where the organization can manage the full lifecycle of its Extras offering in one place. The system supports the configuration of propositions, determines which members are eligible for specific services, and ensures that offers are presented in a relevant context through the Menzis app.

At the same time, the platform provides operational control for managing partner offerings and monitoring how propositions are used. This allows Menzis to ensure availability, maintain oversight of collaborations with service providers, and continuously optimize the Extras portfolio.

“From the start of the project, the goal was to create something Menzis could continue building on," says Sherwin Shahbazi, Project Manager at CLEVR. "By moving the proposition logic into a dedicated backend platform, the team now has a scalable foundation that makes it much easier to introduce new services, work with partners, and expand the Extras ecosystem in the future.”

Results: Greater agility and stronger member relevance

Although the solution has only recently gone live, Backend Propositions has already changed how Menzis can manage and expand its Extras offering, enabling teams to:

• expand and manage the Extras offering with greater speed and independence
• introduce new services, partnerships, and digital health propositions more easily
• tailor offerings to different member groups and insurance packages
• maintain better oversight of partner collaborations and service availability
• continuously evolve the Extras ecosystem as member needs and market conditions change

Where the Extras offering was previously tied to app release cycles and development dependencies, the organization now has a dedicated platform that unlocks a new level of operational flexibility.

Teams can manage, expand, and refine the Extras ecosystem directly, enabling Menzis to introduce new services and partnerships more dynamically while continuously adapting the offering to member needs in a fast-changing healthcare landscape.

A flexible digital foundation where it matters most

Delivering the solution required close collaboration across multiple teams between CLEVR, and the Menzis middleware and app team. By working together from the start, the teams were able to define how the backend should function, how it would integrate with the app and middleware layers, and how the experience would appear to members, ensuring both technical and user perspectives were aligned before development began.

“Our goal was to offer the Extras to our members starting January 1, 2026," adds Siona. "We began the preparation phase in summer and started building in September. CLEVR, as part of the broader backend team, played a key role in successfully delivering the solution, remaining accessible, engaged, and solution‑oriented whenever questions arose.”

Backend Propositions ultimately gave Menzis exactly what the organization was aiming for: a secure and flexible environment in which teams can manage and expand the Extras ecosystem with far greater control and independence, and deliver personalized and meaningful services while respecting the strict governance protocols of the sector.

Together, Menzis and CLEVR have set the foundation for a flexible and effective digital operating model that strengthens how the insurer connects digital services, member experience, and commercial strategy. Today and in the future.

Build tomorrow, together with CLEVR.

As the central business intelligence hub for Dutch healthcare, Vektis plays a vital role in ensuring that quality care remains accessible, affordable, and data-driven. From managing a state-of-the-art national data warehouse to delivering insights that guide healthcare policy, Vektis' platforms form the foundation on which insurers, providers, and policymakers base their work, ensuring efficiency, transparency, and trust across the healthcare value chain.

However, managing and interpreting the vast and ever-changing landscape of healthcare regulation is no simple task. Dutch health insurers process millions of claims annually, each subject to detailed national regulations, and those regulations rarely stand still.

This is where CLEVR comes in.

With the goal to optimize how these regulatory controls are created, validated, and shared industry-wide, Vektis partnered with CLEVR to support them in optimizing a future-ready solution that streamlines regulatory compliance, fosters collaboration among all health insurers, and ensures full transparency.

The challenge: Complexity, compliance, and coordination

Each year, new legislation and policy updates from the NZa (Dutch Healthcare Authority) require rapid translation into operational standards that must be quickly adopted and implemented. This constant motion creates immense pressure for insurers to interpret, translate, and apply these rules consistently, and even more so in a traditionally fragmented landscape.

The BFT platform was specifically developed to address this challenge by providing health insurers across the Netherlands with a unified regulatory language and real‑time access to updated terminology and policy information. And Vektis needed to ensure that it could continue to evolve smoothly as both technology and regulation advanced.

That required expert guidance, structured optimization, and a future-proof Mendix upgrade and CLEVR, as a selected implementation partner was tasked to rebrand the BFT platform, manage a seamless migration, and ensure its smooth integration within the Vektis infrastructure.

The solution: Supporting, and future-proofing the BFT Platform with CLEVR Support

Since the BFT application (originally created by Zilveren Kruis) is built on Mendix low code, CLEVR Support began immediately to map out areas for improvement, define clear goals, and outline the steps to achieve them. Together with Vektis, they modernized infrastructure, streamlined operations, and enhanced overall performance, bringing proactive monitoring and best practices into every phase of the application lifecycle.
‍

"When Vektis chose CLEVR Support as the maintenance and operations partner for the BFT application, we were genuinely thrilled,” says Michel Langras, Support Manager at CLEVR Support NL. “The real challenge was ensuring robust, continuous, and dependable functionality, without disruptions, performance issues, or any compromise to compliance.”
‍

CLEVR Support upgraded the platform to the latest Mendix 10 version, ensuring the BFT application has access to Mendix’s newest capabilities, performance enhancements, and long-term platform support. This allowed Vektis to future‑proof the environment, providing a stronger foundation for ongoing improvements, security, and functionality expansion, as the tool evolves to facilitate increased data volumes and workflow complexity.

The result? A single source of truth for all healthcare control definitions in the Netherlands, supported by a structured, transparent workflow that ensures each phase, from rule creation to publication, is fully traceable, standardized, and compliant.
‍

“The aim was to guarantee continuity and make BFT future-proof and adapt to market needs,” says Armin de Klerk, Business Analyst at Vektis. “And CLEVR had already proven its capability in the original implementation, making them the perfect partner to collaborate with and take the platform to the next level.”
‍

‍

Impact: Maximizing performance and supporting long-term growth

Today, more than 4,000 active LCBs are maintained within the BFT system, redefining how the entire sector collaborates and manages compliance, and creating business opportunities that extend far beyond operational efficiency.

CLEVR Support not only enhanced performance. Together with Vektis they gave the BFT platform a solid foundation for a more connected, intuitive environment that empowers users to collaborate and innovate with confidence.
‍

“Our role as CLEVR Support is to make sure the systems our customers depend on continue to perform at their best,” continues Michel. “For Vektis, that means keeping the BFT application stable, secure, and up to date, so it can continue to serve the insurers for years to come.”
‍

Key Benefits Delivered:

Implementing an application is only half of the journey. In today’s fast-moving digital landscape, you need your app to perform flawlessly, deliver consistently smooth user experiences, and scale seamlessly as business demands and user expectations increase. And this is especially true for Mendix applications, which often become integral to core operations.

As low code applications mature, they inevitably expand in scope and complexity and, over time, they might slow down, or encounter recurring bottlenecks, that impact scalability, maintainability, and user satisfaction across core business functions. This is where continuous optimization becomes vital to sustaining performance and ensuring they remain reliable drivers of digital operations. 

A client of ours faced exactly these challenges when during critical business periods, system slowdowns and instability started impacting promotions, imports, and daily operations. Searches returned delays, large data imports overloaded servers, and certain queues and interfaces were draining system resources.

Fortunately, CLEVR was able to step in with expertise and structured diagnostics to restore stability and build confidence. As a trusted partner, our team ensured operations continued smoothly, downtime costs were minimized, and the user experience remained protected during periods of peak demand.

CLEVR’s diagnostic approach to Mendix performance

In industries where reliability and speed are directly tied to revenue and customer satisfaction, a performance-first mindset is essential from day one. Recognizing this, our support team started immediately, initiating a Performance Diagnostics Scan to uncover underlying structural bottlenecks that could potentially cause the application to experience instability across critical operations.

Unlike routine monitoring or basic incident response, the Performance Diagnostics Scan provides a targeted, in-depth evaluation and is specifically designed to rapidly identify the top long-running actions, predict capacity needs, and provide clear recommendations for future optimization. This makes it particularly valuable during periods of high demand, as demonstrated in this specific retailer’s case.
‍

“Designed with CLEVR’s deep expertise in low code support, the Performance Diagnostics Scan makes it fast and efficient to identify bottlenecks and enhance application performance,” says Richard Pluim, Team Lead Support at CLEVR. “This allows us to directly intervene at the most critical pain points that impact stability and growth.”
‍

By leveraging log analysis, Mendix Cloud alert monitoring, performance tooling, and user behavior review, including manual tests in both development and acceptance environments, we were able to successfully replicate the issues and pinpoint their root causes.

Key performance bottlenecks identified

Our diagnostics revealed several areas where the application was being stressed, particularly in search, data handling, and queue management. Rapid application growth combined with inadequate input handling and insufficient safeguards for heavy data processing made the system vulnerable to instability during periods of growth and peak demand.

More specifically, the team identified the following problems:

• Free Search functionality: attempted to fetch millions of articles due to unfiltered input (e.g., empty values or duplicate separators), causing unnecessary load and slowed down results.
• Large data imports: as increasing demand pushed more and more imports through the system, the lack of batching or limits created database overload and disk spikes above 75%, which resulted in timeouts.
• Low-performing queues: under heavy load, certain queues were draining system performance, primarily due to resource constraints and lack of optimization.
• Interfaces importing article data: certain services, like Article data imports, struggled with exceptionally large volumes, as they lacked mechanisms to process and validate input efficiently.

‍

Targeted optimization solutions

Implementing the solutions required both precision and care. Even though troubleshooting was not without its challenges, some issues were intermittent and difficult to reproduce, with years of experience handling Mendix applications and an in-depth understanding of the client’s environment, our support team acted quickly and effectively to restore stability.

Restoring performance without disrupting the client’s live production environment was a top priority and as such, quick wins like urgent restarts were applied immediately to resolve critical issues, while fixes that required careful testing and scheduling around peak business periods were implemented later to ensure a holistic and lasting solution.

Overall, the solutions our team implemented were the following:

• Optimized search queries by filtering out empty values before execution.
• Introduced thresholds and batching for large imports, supported by monitoring dashboards to track duration.
• Applied server restarts and queue tuning to stabilize urgent issues.
• Suggested future-proofing strategies to handle high data loads more efficiently.

Measurable results and business impact

The implementation process was carried out in close collaboration with the client’s internal team. Open communication, regular check-ins, and alignment on priorities ensured the solutions were delivered smoothly, and with minimal disruption to ongoing operations.

This collaborative approach allowed both teams to work towards a shared goal of restoring stability and enhancing user confidence by delivering on key measurable results:

• Search performance became fast and stable, even for long EAN lists.
• System stability improved with far fewer timeouts and Mendix Cloud alerts.
• End users experienced smoother workflows, especially during promotions and imports.
  ‍

“Performance improved dramatically. From being one of the slowest applications in the chain, it became one of the fastest, causing performance gaps in other applications to become visible, continues Richard. “This is how strategic performance optimization can drive efficiency across the entire application landscape.”

Future stability with CLEVR Mendix support

After implementation, our team made sure to embed a proactive monitoring approach so that any potential issues could be tracked and addressed before they impact operations. Thanks to this, performance has remained stable with no recurrence of the issues previously identified, even during high-load periods.

This case highlights the importance of having a tailored Mendix support partner that can deliver immediate, measurable improvements without lengthy projects or downtime.

ANWB Retail is part of the Royal Dutch Touring Club (ANWB), a trusted household name in the Netherlands known for its wide range of mobility, travel, and roadside assistance services. With over 5 million members, more than 70 retail stores across the country, and over 80 million annual visits to anwb.nl, ANWB plays a vital role in the daily lives of Dutch consumers.

As a leading retail organization within this ecosystem, ANWB Retail manages a dynamic calendar of promotional campaigns across multiple channels. While the existing processes had served the business well for years, the growing complexity of campaign planning and the need for faster, more integrated collaboration prompted a search for a smarter, more scalable solution. ANWB turned to CLEVR to help transition from a fragmented, spreadsheet-heavy workflow to a fully digital, user-friendly platform that could support real-time coordination and future growth.

By using Mendix combined with our deep experience in the retail sector, CLEVR co-created a solution tailored to ANWB's unique promotional workflows, aimed to set them apart in an increasingly competitive market.

The challenge: Manual processes, disconnected tools

Even though 30%-35% of daily tasks could be automated by 2030, many consumer businesses are still constrained by disconnected spreadsheets and manual workflows. This often leads to delays, communication breakdowns and missed commercial opportunities, which was exactly the case at ANWB Retail.
‍

"Information was everywhere," says Koen Berends, Project Manager at ANWB Retail. "The whole process was managed in separate excel files, and there was a lot of email communication sent back and forth, making it difficult to track progress and maintain version control."
‍

In addition, consistent approvals were hard to ensure, as many decisions were made in meetings or informal conversations, without a central view of responsibilities, deadlines, or outcomes.

All of this, not only created unnecessary manual work but also significantly delayed the launch of new campaigns. To address these inefficiencies, ANWB needed a centralized platform that could simplify approvals, improve transparency, and enable cross-functional teams to collaborate more effectively in real time.

The CLEVR solution: Tailored. Scalable. Connected.

To avoid embedding this complexity into a new ERP system, ANWB decided to decouple promotion planning entirely and worked closely with CLEVR to map out a tailored solution that aligned with their specific needs.
‍

“At CLEVR, our process starts with a deep-dive assessment alongside the customer and one of our industry experts,” says Angelo van Dasselaar, Team Lead NL Services at CLEVR. “That’s where our real strength lies, combining sector-specific knowledge with cutting-edge technology and a collaborative approach to turn ideas into scalable, real-world solutions.”
‍

Together we built a custom Promotions Manager, that brings together all key stakeholders into one connected platform — from marketing and buying to merchandise planning and studio teams.

The new Promotions Manager solution was designed to support every step of the retail campaign process, including:

-> Marketing calendar planning for annual promotional campaign
-> Real-time collaboration between marketing, buying, and planning teams
-> Budget alignment by merchandise planners
-> Approval workflows withlocked steps per role (category, planning, marketing)
-> Centralized image management and auto-generated briefings for the design studio

The result? A process that's not only faster, but also far more transparent and collaborative, ensuring everyone is working on the latest version to eliminate double work and unnecessary costs.
‍

“What sets this solution apart is that it's built on CLEVR’s Promotions Manager template; a robust foundation shaped by our team’s extensive industry knowledge and experience serving multiple retailers,” adds Angelo.
‍

This template provides a ready-made starting point that can be tailored to meet any specific business requirement, no matter how unique. By leveraging Mendix low code technology, the solution is not only highly customizable, but also fast and easy to implement, significantly accelerating time to market.
‍

“You can tell it’s really made to support this specific process — tailored to retail promotions," continues Koen. "If you go for a more general campaign manager, you don’t get this level of end-to-end support. Everything you need as a retailer is in there. We couldn’t find that anywhere else.”

The results: A streamlined promotions engine

By combining low code technology with CLEVR’s deep expertise in the retail sector, ANWB Retail was able to unlock measurable improvements across their operations.

• Higher Efficiency: Lead time to launch a promotion was reduced by 20%, enabling the business to respond faster to market needs.
• Improved Focus: With fewer people required to manage operational tasks, teams can now dedicate more time to planning, budgeting, campaign design, and creative decisions.
• Better  Collaboration: Clear role-based approval flows replaced fragmented emails and meetings, ensuring a smoother, more transparent process.
• Controlled Processes: Approval steps are locked by role, so no one can alter promotions once approved. This ensures everyone works on the latest version, eliminating double work, confusion, and unnecessary costs.
• Centralized  Information: All relevant data, assets, and tasks are now housed in a single platform, boosting accountability and visibility.
• Fewer Errors: Automation reduces repetitive manual work and minimizes the risk of inconsistencies.

With greater transparency, structured approvals and centralized data, ANWB Retail has laid the groundwork for a more scalable and controlled future, empowering their Promotions Manager to not only optimize planning and coordination, but to also drive business impact with greater agility and confidence. 

Partnering for Retail impact and operational excellence

From the very start, CLEVR took on the role of more than just an implementation partner. By combining technical expertise with a deep understanding of ANWB’s operational challenges, CLEVR offered structured guidance and best practice insights tailored to the retail industry, challenging existing processes when needed to reduce complexity.
‍

"It was one of the smoothest implementations we've done recently," adds Koen. "CLEVR supported us not just technically, but with a real understanding of the commercial side of things, helping us make smart process decisions, rather than simply customizing for the sake of it."
‍

Thanks to the "first-time-right" nature of low code technology, CLEVR together with ANWB were able to significantly accelerate the development process, meaning fewer bugs, less rework, and faster testing cycles. This allowed ANWB to stay within deadlines and budget, without compromising quality.

Next steps: Future-ready Retail management

This optimization was part of a broader transformation effort within ANWB Retail, aimed at modernizing core retail operations. With promotions now digitized and streamlined, the company has laid the groundwork for future digital growth.

At CLEVR, we don’t just deliver software, we partner for transformation. As ANWB’s needs evolve, our team remains a trusted guide, helping to scale and adapt solutions that truly serve the business.

How CLEVR and Naviva created an essential digital companion for expecting parents

In the world of maternity care, providing timely and reliable information is critical for both new and expecting parents. Recognizing this need, Naviva Kraamzorg embarked on a digital transformation journey to enhance its client engagement and information accessibility.

The result? The Nieuw Leven App — a Mendix Native Mobile application – available in the App Store and Google Play Store - developed in close collaboration with CLEVR.

The vision: From paper to digital excellence

For years, Naviva relied on newsletters, printed magazines, and website content to inform expecting parents. However, these methods inherently lacked interactivity and personalization. During the pandemic, face-to-face contact was restricted, further highlighting the need for a digital solution that could facilitate real-time engagement.

Hanab Telecom Infra (Formerly known as VolkerWessels Telecom) is a cornerstone of the Netherlands’ digital society, tasked with designing, building, managing, and maintaining telecommunications infrastructure across the Netherlands. 
Their work ensures millions of people have reliable internet, can study online, use smart devices, and stay connected in today’s digital world.

At the heart of Hanab Telecom Infra’s operations is the Workflow Infratechniek, a powerful system that coordinates over 60,000 infrastructure projects —from the initial intake of project data to completion and feedback. This application is integral to every stage of all grid projects across the Netherlands, from onboarding and design to planning and delivery.  
 
When a project begins, subcontractors hired by Hanab for a project provide details such as location, timelines, and personnel, which feed directly into Workflow’s system. The application then structures tasks, assigns roles, and checks every step is signed off before users can "advance” to the next phase of a specific project. 
 
The Workflow application integrates with the Netherlands’ Digital Collaboration Platform (DSP), a standardized messaging system maintained by Mijn Aansluiting, to help keep things running smoothly. This platform establishes communication between firms like Hanab, subcontractors, and network operators, so important infrastructure projects like fiber optic installations and underground utility connections can be carried out as efficiently as possible. 
 
However, maintaining and improving such a complex system requires third-party expertise from the digital sphere–which is where CLEVR comes in as a Platinum Partner for Mendix low code. Mendix is a platform that allows applications to be built quickly and flexibly without the need for extensive coding knowledge (hence the term “low code”). CLEVR has over 20 years of experience implementing Mendix solutions across industries, including the manufacturing, energy, utilities, and marine industries, and was tasked with working alongside Hanab to upgrade the Workflow application. 
 
In this collaboration, CLEVR supported Hanab in a crucial upgrade to the DSP, which involved transitioning to more modern REST APIs and implementing advanced security protocols like OAuth 2.0 (which we’ll explain below). These upgrades allow Hanab to maintain the reliable and secure systems the Netherlands depends on.

 
The Challenge

The DSP 2.0 integration posed a set of challenges for Hanab Telecom Infra; at its core was the need to modernize the underlying technology of the Workflow application. Speaking to Hanab’s Citizen Developer, Roeland Drok, CLEVR was an easy choice when it came to creating a partnership; “We tried another supplier for a while and well, there was a difference in collaboration. CLEVR knows what to do; they understand the business, they understand us.”

Modernizing Communication: SOAP to REST APIs 

It’s important to understand that APIs are like digital messengers that allow systems to talk to each other. Modernizing these messengers is like upgrading from a postal service to instant messaging, which is clearly more efficient and easier to manage when it comes to just sending written communications. 

 
One of the critical changes involved transitioning from the outdated SOAP (Simple Object Access Protocol) to the more modern REST (Representational State Transfer) APIs. While SOAP relies on heavy, XML-based messaging, REST uses the lighter JSON format, making data exchanges faster and more efficient.  
However, this shift was not just about adopting a new standard, it required a restructuring of how information flows between systems. This included remapping processes and ensuring that all parties in the network, from subcontractors to end users, could operate seamlessly under the new system. 

Upgrading the Workflow Application: Mendix 8 to Mendix 10

Another challenge was upgrading the Workflow application, which had been in operation since 2017, to the latest version of the Mendix platform. This upgrade was far from straightforward, especially since it had to be executed without disrupting the management of thousands of ongoing projects. These projects represent a wide array of telecommunications and utility networks, all progressing through multiple phases such as intake, design, and execution.  
 
“We upgraded from Mendix version 8 to version 10. I couldn’t do that myself—no one within Hanab could do that.”

Securing the System: OAuth 2.0

Security was another key point within the project. The existing system used certificate-based authentication, a method that had become outdated and less effective against modern cybersecurity threats. The transition to OAuth 2.0, a widely accepted security protocol, introduced a new level of protection for Hanab’s sensitive project information. However, implementing OAuth 2.0 was no small feat—it involved configuring secure access tokens, integrating identity verification systems, and making sure every user and system could authenticate seamlessly under the new framework.

Collaboration Across Teams

Along with the technical challenges, the DSP 2.0 integration required collaboration between Hanab’s internal teams, subcontractors, and CLEVR. This meant aligning priorities, coordinating schedules, and ensuring that all parties had the tools and knowledge needed to transition smoothly. Such a large-scale collaboration increased the complexity of the project, making it essential to have an experienced partner.

CLEVR’s Solution

“CLEVR has helped us since the beginning–they built it from scratch, and we don’t have to worry when CLEVR’s on the project. They know what to do.” 

Roeland Drok, Citizen Developer at Hanab Telecom Infra

CLEVR helped the team at Hanab carry out the DSP 2.0 integration by using its vast Mendix expertise and management experience to keep the project on track and successful despite its complexity.

Transitioning to REST APIs

One of CLEVR’s key contributions was modernizing the data exchange system by transitioning from SOAP to REST APIs. This shift involved significant technical changes, including converting message formats from XML to JSON and redesigning how systems communicated. CLEVR’s team not only executed these changes but also made sure there was a seamless integration between the Workflow application and external systems like the Digital Collaboration Platform (DSP).

 
Implementing OAuth 2.0 for Enhanced Security

As you’d expect from a nationwide digital project, security was the priority, and CLEVR led the charge by implementing OAuth 2.0, a modern authentication protocol designed to secure sensitive data. This involved creating secure access tokens and integrating identity verification processes to replace the outdated certificate-based authentication. CLEVR’s ability to adapt to these new requirements ensured Hanab’s systems met the latest security standards without disrupting operations. 
 
“OAuth 2.0 was completely new for me… CLEVR took care of it for us, connecting with the right people and making it work.” 
 
Roeland Drok, Citizen Developer at Hanab Telecom Infra

Upgrading to Mendix 10

The upgrade of Hanab’s Workflow application from Mendix version 8 to version 10 was a critical component of the project. This task demanded extensive knowledge of Mendix and the Workflow application itself, as the system handles over 60,000 projects across multiple stages of development. CLEVR’s team meticulously planned the upgrade to make sure that all existing features and integrations functioned as intended while introducing the new capabilities of Mendix 10.

Flexibility and Last-Minute Adaptation

CLEVR’s flexibility and responsiveness were critical in overcoming challenges and quick changes in direction. When Hanab needed new integrations at the last minute to align with a broader ERP migration, CLEVR quickly adjusted its plans and delivered the required updates on time. "It was really last-minute, but CLEVR helped us with their planning and willingness to move forward. They made sure the new integrations were completed,” said Drok. 

Seamless Collaboration

CLEVR’s approach centered on an ability to collaborate seamlessly with both Hanab and its subcontractors. This extended beyond technical expertise; CLEVR’s familiarity with Hanab’s systems and processes meant they could anticipate needs and deliver solutions with minimal oversight. This not only saved time but also reduced the risk of errors, a critical factor given the project’s complexity. According to Drok, “Working with CLEVR proved to be a lot smoother [than with other suppliers].”

Impact and Future Outlook: Stronger Together

The DSP 2.0 integration has already delivered significant improvements to Hanab’s operations. By upgrading to modern REST APIs and implementing advanced security protocols like OAuth 2.0, CLEVR has enabled Hanab to streamline communication with subcontractors and improve the overall efficiency of their projects. This enhanced collaboration ensures that Hanab can deliver critical infrastructure projects, such as fiber optic installations, faster and with greater precision. 
 
For Hanab, this isn’t just about technology—it’s about maintaining their role as a cornerstone of the Netherlands’ digital infrastructure. The Workflow Infratechniek, now upgraded to Mendix version 10, is better equipped to handle the evolving needs of over 60,000 active projects, ensuring that Dutch citizens and businesses continue to enjoy reliable, high-speed connectivity.
