Built to win

We invest from pre-seed to Series A in scaling renewable energy and market-driven removals, reinventing resource-intensive industries, and enabling adaptation and resilience. Our portfolio companies innovate where incumbents have stalled progress and where clean technology wins not because it should, but because it’s cheaper, better, and more efficient.
