About us

The world needs greentech innovations to reach net-zero and circularity, but a wealth of research inventions never gets used at scale. BigCircle Ventures brings a unique flow of early-stage innovations to the market, that would otherwise stay untouched on a shelf, hidden in a university, research institute or company lab. By using a long-proven model for discovering, nurturing and funding, we aim to be the world’s leading greentech venture builder and boost the world’s journey towards sustainability.
