ColibriTD closes €4m seed round for quantum simulation platform
What's the deal? Paris-based ColibriTDDealroom has a profile for this one. Try Dealroom → closed a €4 million seed round on 27 August 2026. The round was led by Earlybird Venture Capital, with participation from Symbia VCDealroom has a profile for this one. Try Dealroom → and Medin VC. It follows Earlybird's €1 million pre-seed investment announced in September 2023. ColibriTD intends to use the new capital for research and development, hiring quantum researchers and domain-expert engineers, expanding hardware and academic and industrial partnerships, and international growth.
What the company builds: ColibriTD develops a quantum-powered multiphysics simulation platform centred on H-DES, its proprietary variational quantum algorithm for solving partial differential equations. PDEs underpin simulations of fluid dynamics, material deformation, energy systems and other coupled physical phenomena. ColibriTD's stated goal is to address engineering problems where classical methods face increasing computational demands, while using quantum technologies to improve performance, accuracy and cost efficiency.
Commercial focus: The company reports co-construction work across six computationally demanding sectors, including defence and aerospace, space and climate science, semiconductor design, nuclear energy, automotive engineering and quantitative finance. Its QUICK-PDE Qiskit Function is available through the Qiskit Function Catalogue for IBM Quantum Premium and Flex Plan users. ColibriTD's platform is hardware-agnostic and is intended for industrial applications rather than research alone, with the company seeking additional co-construction partners in finance, defence, semiconductors, aerospace, automotive and energy.
Company context: Founded in Paris in 2019 by Laurent Guiraud and Hacène Goudjil, ColibriTD describes multiphysics simulation as a critical workflow for advanced engineering and materials development. The funding gives the company resources to deepen H-DES, support client engagements with specialised staff and broaden the partnerships needed to move quantum-powered simulation into more industrial settings.
