Paris-based ColibriTD secures €4M to expand its quantum-powered multiphysics simulation platform

Paris-based quantum software company ColibriTD, which specialises in multiphysics simulation, has raised €4 million in a Seed funding round.

The round was led by Earlybird Venture Capital, with participation from SymbiaVC and Medin VC. The latest funding follows Earlybird’s initial €1 million pre-Seed investment in the company.

“Hardware may unlock quantum computing, but software determines where its value is created. ColibriTD has built a differentiated software platform with the scientific credibility and industrial traction to become the decision layer for quantum applications. We’re proud to continue supporting the team on that journey,” said Dr. Frédéric Du Bois-Reymond, Venture Partner at Earlybird Venture Capital.

Founded in Paris in 2019 by Laurent Guiraud and Hacène Goudjil, ColibriTD is a DeepTech startup developing a quantum-powered multiphysics simulation platform. Its technology is built around H-DES (Hybrid Differential Equation Solver), a proprietary variational quantum algorithm designed to solve partial differential equations (PDEs).

According to ColibriTD, PDEs form the mathematical foundation of multiphysics simulations and are used to model complex systems such as fluid dynamics, material deformation and financial risk. The company believes these problems require a level of precision and computational complexity that traditional computing and artificial intelligence cannot fully handle.

“AI excels at pattern recognition and statistical approximation. It cannot replace the exact, physics-grounded solutions that high-stakes industrial engineering demands. This is precisely where quantum computing opens a new frontier, and where ColibriTD has planted its flag,” mentioned the company. 

The company also points to IBM’s view that solving partial differential equations (PDEs) is an area where quantum computing could deliver significant benefits in the near term. ColibriTD’s QUICK-PDE Qiskit Function is also available through the Qiskit Function Catalogue for IBM Quantum Premium and Flex Plan users.

Over the past several years, ColibriTD says it has completed co-development projects across six computationally intensive industries. These include defence and aerospace, with applications such as radio-frequency design and propulsion combustion modelling, as well as space and climate science, semiconductor design, nuclear energy, automotive engineering and quantitative finance.

“When we founded ColibriTD in 2019, our vision was to move quantum computing past academic theory and deliver tangible business value to industry. Today, we have reached an inflection point. With seven successful co-construction projects across six sectors, we’ve proven that quantum-powered simulation is a present capability, not a future promise. This seed round accelerates our momentum as we scale our hardware-agnostic platform to help more enterprises capture the quantum advantage,” said Dr. Laurent Guiraud, co-founder and CEO of ColibriTD.

ColibriTD plans to use the new funding to strengthen R&D for its H-DES technology, hire quantum researchers and engineers with industry expertise to support customer projects, expand its hardware capabilities and deepen its academic and industrial partnerships. The company also aims to accelerate international expansion and build the foundation needed for future growth.

ColibriTD is also looking for co-construction partners, particularly companies in finance, defence, semiconductors, aerospace, automotive and energy.
