From research to real-world encrypted computing
Belfort unites experts committed to a future where knowledge is free to flow, and trust is never compromised.
In an AI-first world, trust is all you need. The future of computing is encrypted
Belfort enables that vision by accelerating encrypted compute to make it practical at scale, ensuring that sensitive data can be processed without ever being decrypted.
A spin-off from KU Leuven’s world-renowned COSIC lab, Belfort combines breakthroughs in hardware and algorithms to build the next layer of secure computing.
Performance without compromise
What once took hours now takes minutes.
Belfort brings encrypted compute within reach.
Seamless adoption
Purpose-built hardware integrates effortlessly, turning encrypted computing from concept into reality.
Security as a foundation
Data remains protected throughout every operation; confidentiality is inherent, not optional.
“For decades, we’ve explored how to make computation secure by design. With Belfort, we’re finally bringing those ideas into practice.“

The Visionaries Driving Secure Computing Forward
Belfort’s team of leading cryptographers, mathematicians and entrepreneurs makes encrypted computation practical and performant at scale.
Jean-Philippe
Bossuat
Jean-Philippe Bossuat wrote the world's most used open-source FHE library. At Belfort, he makes Cyclops, our accelerator library, production-grade. He is the original author and lead developer of Lattigo, and previously held cryptography roles at EPFL and Tune Insight.
Robin
Geelen
Robin Geelen is one of the world's foremost experts on FHE bootstrapping and the creator of the GBFV scheme. At Belfort, he works on bringing cutting-edge research into production. He co-authored the BASALISC accelerator and created GBFV during his PhD at KU Leuven COSIC.
Can
Elgezen
Can Elgezen is one of a handful of engineers worldwide writing the fastest cryptographic GPU code in production. He builds the CUDA kernels behind Belfort's Encrypted Computing offering. He spent four years at Supranational authoring some of the fastest open-source NTT kernels.

David
De Troch
David has significant experience in cryptography and decentralized systems. Before joining Belfort, he was a software engineer at IOTA and one of its ecosystem spin-out projects, contributing to core infrastructure and tooling. At Belfort, he focuses on software integration and system development for encrypted computation.
We’re building at the edge of what’s possible
Working on encrypted compute means tackling hard problems every day — in math, hardware, and systems. We don’t shy away from complexity, we lean into it together
We’re a team sport
We believe the best breakthroughs happen when cryptographers, hardware engineers, and builders work side by side. No silos, no egos, but a shared mission and a bias for collaboration.
We value speed and rigor
Our work touches national security, healthcare, and financial systems. That requires uncompromising standards, but also the agility to ship and learn fast. We balance both.
We’re in it for the long run
We know encrypted compute won’t be solved overnight. We’re building patiently, with resilience, and with a deep respect for both science and society.
We keep it real
We’re ambitious, but we don’t take ourselves too seriously. A good laugh and celebrating small wins help us keep going through the big challenges.
At Belfort, you work at the technological frontier where theory meets operation
TRUST IS ALL YOU NEED
Process data securely.
