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

About Clean Energy Ventures

Having started and run multiple companies ourselves, we understand what it is like to be a climate tech entrepreneur.

At Clean Energy Ventures we’re beating back climate change through energy innovation. We fund disruptive, capital-light technologies and business model innovations that can reshape how we produce and consume energy. Each startup we invest in has the potential to substantially reduce greenhouse gas emissions between our investment and 2050.

Since 2005, our leadership team has invested in over 40 climate tech startups alongside our angel-investor partners at the Clean Energy Venture Group, prominent venture capital firms, leading OEMs, global materials companies, oil majors, and more.

Beyond funding, we provide hands-on guidance through dedicated leadership coaching, strategic marketing, IP development and active board participation. Our collection of 19 Venture Partners guide our startups and enhance our value with their deep technical and operating experience.
