ColibriTD raises 4 million euros to push quantum simulation into industry
The Paris start-up's hybrid algorithm targets differential equations, the core of multiphysics simulation, with pilot projects at Thales, ESA and BMW.
ColibriTD, a Paris deep-tech founded in 2019, closed a 4 million euro seed round on 27 August 2026, led by Earlybird Venture Capital. The company develops H-DES, a hybrid quantum-classical algorithm for solving differential equations, and says it has completed seven co-construction projects with partners including Thales, the European Space Agency and BMW.
Why it matters
Differential equations sit under most engineering simulation, from fluid dynamics to material deformation. A start-up funded to prove a quantum contribution there, with industrial partners already on board, is a use-case story rather than a hardware one.
Key takeaways
- Seed round of 4 million euros closed on 27 August 2026, led by Earlybird Venture Capital, which had already put 1 million euros in at pre-seed; SymbiaVC and Medin VC are reported as participants in the round.
- Founded in 2019 by Laurent Guiraud and Hacène Goudjil, based in Paris, about twenty employees.
- Core product: H-DES, a hybrid quantum-classical algorithm for differential equations, delivered through the QUICK platform, which splits work between classical resources and quantum circuits; hardware-agnostic, with runs on IBM, AWS Braket and Quobly.
- Seven co-construction projects claimed with industrial partners including Thales, ESA and BMW; the funds go to R&D and international expansion, with the stated aim of demonstrating an advantage over classical methods.

Its field is not hardware but algorithms. H-DES is a hybrid quantum-classical method for solving differential equations, the mathematics behind multiphysics simulation, from fluid dynamics to the deformation of materials. It is delivered through a platform called QUICK, which distributes computation between classical resources and quantum circuits, and runs on several machines: IBM, AWS Braket and the French silicon start-up Quobly.
ColibriTD says it has completed seven co-construction projects with partners including Thales, the European Space Agency and BMW. The new money goes to research and development and to international expansion, with one explicit goal: showing an advantage over classical methods on real problems, the demonstration the whole sector is waiting for.

BACQ: French benchmarks to measure real quantum performance
A METRIQs-France project building open benchmarks to compare quantum computers on concrete tasks.
BACQ is a French project developing open benchmarks to evaluate quantum computers on concrete tasks. Coordinated by Thales within the METRIQs-France programme, it runs from 2023 to 2026 with a budget of about 4 million euros.

Quobly teams up with TNO and Orange Quantum Systems to industrialise silicon spin qubits
Two Franco-Dutch agreements signed in Eindhoven on 2 September 2026, in the presence of the French President and the Dutch Prime Minister.
On 2 September 2026 in Eindhoven, Quobly signed two memoranda of understanding: one with the Dutch research organisation TNO on characterisation and metrology of silicon spin qubits, one with Orange Quantum Systems on automated, high-throughput testing of quantum chips. Both target the move from laboratory devices to industrial-scale manufacturing.

QbitSoft joins Le Village by CA Paris with a quantum-as-a-service pitch
A small French software company that wants to plug quantum optimisation algorithms into ordinary enterprise systems, without tying customers to one machine.
Le Village by CA Paris, Crédit Agricole's start-up campus, announced in early September 2026 the arrival of QbitSoft, a French company offering quantum as a service: a hardware-independent software layer to integrate quantum optimisation algorithms into corporate information systems. Target uses range from route optimisation and network planning to insurance, fraud detection, finance and defence.
