State and sector
This list brings together California family offices whose recorded investment interests include energy. It can help founders, business owners and fund managers identify potential investors to research, while giving advisors and investors a view of how energy sits alongside other reported interests. The database includes 26 offices, with 20 single-family offices and 6 multi-family offices. San Francisco and Los Angeles have the largest city counts in the list. Energy appears among several focus areas, alongside real estate, private equity, education and venture capital. These overlapping interests matter: a recorded energy focus does not by itself indicate a mandate, preferred instrument or readiness to invest in a particular opportunity. Use the table as a starting point, then check each office’s public materials and investment criteria before reaching out. Public firm-level fields support initial research; additional contact and decision-maker details are available through the full list.

An office is included because its recorded investment interests include energy and its location is in California. That signal is useful for building a research list, but it does not confirm that the office is actively investing, has an open mandate, or considers every energy subsector or deal structure.
No. The recorded interests span several areas. Real estate, private equity, education and venture capital are also common in this list. Review each office’s profile and public materials to understand how energy fits with its broader investment activity.
Start with a concise note explaining the business, the energy segment, the financing need and why the office may be relevant. Refer to a specific public investment interest where possible. Confirm that the office considers your stage, geography and instrument before sending detailed materials.
