TKP goes live with Keylane’s SaaS platform Plexus

A Landmark moment in pension transformation 
As of May 1st, TKP Pensioen becomes the first Keylane customer to transition to the Solidarity Pension Regulation (SPR) under the new Dutch pension system, Wet Toekomst Pensioenen (WTP). This milestone marks a major step forward not only for TKP and Keylane, but also for the broader Dutch pension sector in embracing a more modern, digital-first infrastructure. 

A key enabler of this successful transition is TKP’s new administration system: Plexus, Keylane’s end-to-end, standard SaaS platform built specifically for life and pension providers. 

TKP Pensioen – one of the top three pension service providers in the Netherlands, serving 16 clients and approximately 3.8 million participants – selected Keylane in 2023 following a rigorous evaluation process. TKP was seeking a future-proof IT solution to support the complexity of the new pension landscape. Plexus was selected for its flexibility, configurability, and ability to support digital transformation at scale. 

The role of Plexus in TKP’s transformation
Plexus was already in production with Flexible Premium Regulation (FPR) products at several pension insurers. Building on that success, the platform was configured, integrated, and validated for TKP’s SPR administration. 

Key project milestones included: 

• Seamless integration of Plexus into TKP’s infrastructure 
• Full configuration and SaaS setup tailored to TKP’s needs 
• Execution of multiple test migrations including the conversion process and communication planning to ensure a smooth transition 

This go-live demonstrates that Plexus is ready to support both FPR and SPR pension schemes, positioning TKP and its clients to meet the requirements of WTP confidently. 

Keylane L&P CEO, Leon de Looff, says: “We are thrilled to announce the successful go-live of Plexus, our end-to-end pension administration platform, at TKP Pensioen, supporting their transition to the new pension system, and the SPR scheme in particular. Plexus is designed to empower the life and pension industry with cutting-edge, SaaS-delivered technology, and we are excited to see the value it brings to TKP and their customers. Thanks to everyone who made this achievement possible. Together, we are shaping the future of pension services.” 

A scalable model for future transitions
TKP’s transition sets a clear blueprint for future fund migrations. With the first implementation now live, five additional industry pension funds serviced by TKP are already preparing for their transitions in early 2026. The project’s structured, repeatable approach ensures other migrations can proceed predictably, efficiently, and within WTP’s timeline. 

“Keylane’s platform Plexus fits our ambition and objective very well: to offer a feasible, explainable and affordable solution for the new pension scheme. Over the past year and a half, we have – in close cooperation with Keylane’s teams – easily set up the SPR pension scheme of our first client in the pension administration. In doing so, we a flexible and scalable multi-client solution with a high degree of automation of all core processes.” says, Jonathan Koopmans, CTO at TKP Pensioen.  

Looking ahead
This achievement reflects the power of close partnership between TKP and Keylane and highlights the value of a strong, adaptable SaaS platform. With Plexus, Keylane is proud to deliver the foundation for a more agile, compliant, and digital pension system – not just for TKP, but for the entire industry.
