An entrepreneur’s pursuit of disruptive technologies can seem like a long, lonely road

The Principals of Clean Energy Ventures have been investing in, supporting and mentoring early stage clean energy startups together since 2005.

Having started and run multiple companies ourselves, we understand what it is like to be climate tech entrepreneurs, and are committed to driving success for the companies we invest in.

Clean Energy Ventures (CEV) was launched out of the private investment group Clean Energy Venture Group (CEVG). We have been investing in climate tech startups for more than a decade alongside our partners from CEVG as well as leading venture capital firms and strategic investors such as oil majors, materials companies, and leading OEMs across the energy and related industries.


Clean Energy Ventures has a deep bench of Venture Partners who, together with the Principals, represent decades of combined clean energy operating and climate tech investing experience. Our Venture Partners assess, build and mentor management teams at our portfolio companies to help them scale. The team holds over advanced degrees from MIT, Harvard, Cornell, Yale and other leading academic institutions and has been instrumental in creating and supporting the clean energy ecosystem.
