Clean Energy Venture Group

What Clean Energy Venture Group does

Clean Energy Venture Group (CEVG) is a Brookline, Massachusetts-based private angel investment group founded in 2006 that provides seed capital and management expertise to early-stage climate-technology startups. The firm consists of 35+ partners who are seasoned operating executives, entrepreneurs, and investors with backgrounds spanning energy, engineering, commercialization, sustainability, and finance. CEVG targets US and Canada-headquartered companies developing technologies that can significantly mitigate greenhouse-gas emissions, investing across pre-seed, seed, and Series A rounds typically at valuations under $10 million and in companies that can reach trade sale or EBITDA-positive status with under $50 million in lifetime equity financing.

The firm's core product is early-stage climate-tech investment services, delivered through a unified application and diligence pipeline shared with its sister organization, Clean Energy Ventures (CEV), which was founded in 2017 by three CEVG partners and now manages two funds with over $400 million in total committed capital. CEVG also collaborates with incubators, accelerators, industry groups, and strategic corporate partners to source deal flow and support portfolio companies, which span clean energy, energy storage, advanced materials, circular economy, mobility, manufacturing, and software/platform solutions.

CEVG's economics are driven by equity investment returns realized through trade sales, IPOs, or EBITDA-positive outcomes, rather than recurring management fees; the firm explicitly does not charge an application fee. To date, CEVG has made 60+ investments alongside 75+ institutional and strategic co-investors, with at least one disclosed portfolio exit (CodeOn). The partnership has also codified DEI commitments through Civic Salon training, leadership in the Browning the Green Space initiative, and DEI term-sheet clauses applied to portfolio investments.
