About us
We’ve sat in your chair.
Klapeen combines boardroom experience with the hands to build. We have run the kind of businesses we now help — and we run our own company on the AI software we make.
Mathijs Leenheer
Co-founder
Former CPO and COO in IT services, with strategy and M&A work for private-equity-owned companies. Turns business questions into business cases — and business cases into working software.
Ruud Kapteijn
Co-founder
Hands-on IT lead with a track record in business process digitisation, AI-assisted development and large-scale technology delivery.
What we stand for
People first
AI should take work off people’s plates and give them more room for the work that matters — not replace judgement.
Honest advice
If software is not the answer, we say so. If a standard tool does the job, we recommend it.
Proof over promises
Working software early, measured against a business case — not slide decks.
No lock-in
Your data is yours, and if you leave, your code goes with you.
04 — Proof
We run Klapeen on it.
Two founders, one company running on software we built ourselves — and AI agents that work alongside us. If it does not hold up in our own business, we do not sell it to yours.
Where would AI make the biggest difference for you?
Tell us where the friction or the missed opportunity is. We will tell you honestly whether software is the answer.
