Angeleno Group
No summary available yet.
Angeleno Group is the energy transition OG - they were betting on clean tech before it was cool, literally founding the firm in 2001 when 'clean energy' wasn't even in most VCs' vocabulary. The founders are a compelling duo: Weiss brings legal/policy chops from white-shoe law firm O'Melveny and actual White House experience, while Tepper has serious finance credentials (grew a fund from $150M to $2B at Aetna). Their advisory board is genuinely impressive - Janet Yellen, Ernest Moniz, Frances Arnold - these aren't vanity adds, they're heavy hitters who signal serious conviction. In more than two decades, Tepper and Weiss' firm has invested in nearly 40 companies and has led or co-led funding totaling about $3 billion. But here's what matters for founders: they're sector-focused but stage-agnostic, which means they can follow you from growth through exit. The $10-30M check size is real money that moves needles.
- —Best for: Growth-stage clean energy/climate tech companies needing $10-30M and sector expertise
- —Known for: 24-year track record as climate investing pioneers with heavyweight advisory board
- —Watch out for: High bar for proven tech and customer traction - they're not early-stage risk takers
Angeleno Group believes that we are at the beginning of a once-in-a-generation global secular transformation to a low carbon, electrified and highly digitized economy driven by technology and innovation, environmental imperatives and markets and economics. These changes revolve around three major themes: (1) the need for energy independence, (2) the requirements of a stable and reliable energy infrastructure, and (3) imperatives relating to environmental sustainability.

Prior to the formation of Angeleno Group, Mr. Weiss was an attorney at O'Melveny & Myers in Los Angeles, working in the firm's mergers and acquisitions, international and high technology practice groups. He represented multiple Global 1000 clients, including utilities and energy-related companies, in a wide array of private equity and corporate finance transactions. Mr. Weiss also has a significant history of involvement in government, regulatory and public policy entities that deal with the energy sector including work experience in the White House and the United States Congress.
Prior to the formation of Angeleno Group in 2001, Mr. Tepper managed $2 billion in private and public equities and structured securities on behalf of institutional and mutual fund clients while at Aetna (now ING Investment Management). Under Mr. Tepper's management, his funds grew from $150 million to $2 billion, consistently outperformed the funds' benchmarks, and ranked in the top tier of their competitive universe. Earlier in his career, Mr. Tepper held various engineering R&D positions at Bechtel in San Francisco and at M.I.T.'s Advanced Materials Lab in Cambridge under the Department of Energy.
