Sonamu Group
Sonamu Group began operations in 2019 under founder Tina Surh. The firm serves a limited set of families and charitable foundations through a single evergreen vehicle. The portfolio spans public equities, private equity, and opportunistic credit. Positions are held directly or through targeted partnerships rather than broad fund commitments. Geographic reach covers North America and developed international markets. Confirmed relationships include co-speaker appearances with Fleur Fairman at the 22nd Annual Yale PE/VC Symposium in February 2025. Team size remains undisclosed. Surh maintains board roles at Tufts University School of Engineering and Tisch College. The firm lists a sailing yacht among its assets and supports philanthropy through the Boys and Girls Clubs of Boston. No additional offices are recorded. The evergreen partnership structure removes fixed-term capital return pressure. This allows longer holding periods and direct co-investment selection without external limited partner reporting cycles.
