ColibriTD
ColibriTD is a French deep tech startup founded in Paris in 2019 by Laurent Guiraud and Hacène Goudjil. The company develops a quantum-powered multiphysics simulation platform built around H-DES, a proprietary hybrid quantum-classical algorithm for solving complex systems of differential equations. Its hardware-agnostic architecture runs across IBM, AWS Braket, and Quobly. With a team of ~20, including ~12 PhDs, ColibriTD bridges cutting-edge quantum research and real-world industrial applications.
Isentroniq
The quantum computing race is on. Every major player is targeting 1,000s to 10,000s qubits by 2030. But they all face the same bottleneck: cryogenics. Current solutions run too hot, take up too much space, and simply can’t scale to commercial quantum systems. Isentroniq removes this bottleneck. Our dense, near-heatless integrated circuits unlock 1,000x more qubits within the infrastructure that exists today. Backed by a €7.5M pre-seed round in 2025, we’re focused on one thing: making the scale-up physically possible.
QbitSoft
QbitSoft is a French quantum software company that makes quantum computing accessible to businesses. Its Quantum-as-a-Service platform offers ready-to-use applications to solve complex problems in optimization, logistics, risk management, and data processing—without requiring in-house quantum expertise.
