Carbon zero
Where climate solutions outperform legacy systems.
Carbon Zero is the first climate-focused cohort of Hexa Sprint. We invest in climate technologies that economically outperform legacy systems.
As climate constraints reshape energy, industry and infrastructure, entire systems are being replaced - not optimized. Carbon Zero partners with pioneering founders from day one to build the technologies that can win on cost, performance and scale, and help Europe lead the post-carbon transition. Because systems only change when economics win.
What we back
We invest in companies that aim for systemic replacement, not incremental improvement.
We look for solutions that:
- can replace legacy systems at scale
- demonstrate clear economic superiority over incumbents
Where we invest

Electrification
Replacing fossil-based energy and processes with clean, reliable and scalable electric systems.
Low-carbon production
Rebuilding industrial processes and materials with superior economics and resilience.
