What Five Stones Investment Group does
Five Stones Investment Group is a privately held, multi-strategy investment management firm founded in 2020 and managed by Steven Stein, John Stein, and Eric Stein. The firm operates as a family-office-style platform serving a select group of high-net-worth families and invests across the full capital structure, including venture capital, private equity, real estate, public securities, and special situations. The firm maintains a tri-city U.S. footprint with offices in Cincinnati OH, Greenwich CT, and Palm Beach FL, reflecting a deliberate geographic concentration near major HNW wealth clusters.
The firm consolidates 25 years of Stein-family investment experience originating with the 1995 founding of FSI Group and Financial Stocks LP, followed by the 2001 launch of FSI's first private-equity fund in financial services, the 2010 formation of ESS Capital, and the 2017 launch of Five Stones Ventures. Its leadership team combines prior roles at FSI Group (where Eric Stein managed in excess of $5 billion in long/short equity, private equity, and fixed-income assets), Morgan Stanley's Financial Institutions M&A group, the U.S. Treasury Department, the U.S. Department of State, and Bankers Trust Company, alongside board seats at multiple publicly traded and private banks and financial-services firms.
Five Stones monetizes capital under management through management fees and performance-based carried interest, with pricing negotiated individually with each family client and not publicly disclosed. Distribution is relationship-driven, relying on the Stein family's private network across financial services, banking, and public-policy circles rather than mass-market channels. The firm is operationally lean (1–10 employees) and discloses no institutional LP capital, making family-office client retention the central revenue driver.
