Positive Ventures is a pure-play impact-driven investor that backs bold, contrarian, mission-driven founders building technology to solve major social and environmental problems. The firm invests early and describes itself as sector-agnostic, seeking ventures that deliver both large-scale impact and strong financial returns. It views investing for nature and people as strategic business rather than philanthropy. With roots in São Paulo and a presence in San Francisco, the firm aims to bridge the Global South and North, unlocking cross-border opportunities for scalable, transformative solutions.
