Double M Partners

Double M Partners

Double M Partners was established as a single-family office with headquarters in Santa Monica, California, and an additional office in San Francisco. The firm's wealth origin and founding year are not publicly disclosed. Its structure is typical of a family office that manages the financial affairs and investment portfolio of a single wealthy family, maintaining a low public profile. The firm pursues a multi-asset strategy spanning real estate, venture capital, private equity, and credit. It engages in direct co-investments and fund commitments, partnering with external GPs and managers. Geographic focus is primarily the United States, with a particular emphasis on the West Coast and national real estate markets. Specific portfolio companies or deals have not been publicly named. Double M Partners operates with a lean team structure, though exact headcount is not public. The two California offices — Santa Monica and San Francisco — support its investment activities across asset classes. No separate philanthropic or operating-company vehicles have been publicly identified. The firm's recent activity remains undisclosed. The firm's structural differentiator is its disciplined multi-asset approach within a single-family office framework, maintaining operational independence while accessing external manager relationships. Its dual-city presence allows it to source and evaluate opportunities across key US markets without relying on a single geographic hub. The firm's intentional privacy limits external visibility into its portfolio and operations.
