Kenneth Rainin Foundation

About the fund

Obvious Ventures V, the fifth fund from Obvious Ventures co-founded by Twitter and Medium co-founder Ev Williams, focuses on high-impact startups driving systemic change across climate, clean energy, advanced food systems, AI/biotech, and financial inclusion. The fund maintains the firm's distinctive "world positive" investing ethos by deliberately seeking founders and technologies aligned with both outsized financial returns and actionable environmental or social progress. With a 360-degree view across three pillars—planetary, human, and economic health—the team invests with scientific rigor and values alignment, believing that transformative technologies can unlock massive commercial markets while benefiting society.
