EINDHOVEN, THE NETHERLANDS (JULY 1, 2025) — Carbyon, a deep-tech Direct Air Capture company, has secured a strategic investment from ISAI Build Venture, the VC fund created in partnership between ISAI and Bouygues, to accelerate its growth and innovation capacity. Carbyon has developed an innovative, patented technology to capture CO2 directly from the atmosphere. Their ‘fast swing’ technology increases CO2 capacity and thereby significantly drives down unit, energy and project costs – all critical criteria to facilitate large scale deployment. This extension of our series A round that was closed in September 2024, marks a significant step in strengthening Carbyon’s strategic relationships within the industry.
With Bouygues on board as a strategic partner, Carbyon is unlocking opportunities to bring direct air capture into the real world faster. Bouygues' deep process engineering experience is a critical enabler for scaling these technologies. The partnership positions Carbyon to expand into other industries such as green chemicals, including SAF, e-Methane and e-Methanol. With Bouygues' support, Carbyon will be able to accelerate the development of its technologies and achieve greater impact.
