$75M Invested
Capital deployed by our members into early-stage companies building toward a thriving planet, since 2006.
The future of our planet needs more than good intentions. It needs capital, conviction, and community.

E8 exists to mobilize all three. We back early-stage companies building real solutions for a thriving planet: energy generation & storage, transportation, built environment, agriculture, water, and more. We do it together, as a community of investors who've seen that environmental impact and financial returns are complementary priorities.

Community is how we work. Members dig into companies together from screening through diligence, and make their own decisions about where to write checks. Founders who come through E8 leave better equipped, because we take time to understand their company and share honest feedback.

We've been investing since 2006, and we're here for the long run.
