6|21 Private Wealth
6|21 Private Wealth was established in 2006 by Jere L. Cowden and J. Rock Tonkel, Jr., two professionals who previously held senior roles in wealth management and investment advisory. The firm operates as a multi-family office, serving a limited group of ultra-high-net-worth families rather than a single founding family, which distinguishes it from traditional single-family offices. The firm allocates capital primarily through direct investments across private equity, real estate, infrastructure, and energy. 6|21 Private Wealth co-invests alongside its client families, participating in deal sourcing and due diligence on a deal-by-deal basis. Its geographic focus is North America, with occasional exposure to select European assets (per SEC filings, 2023). The firm maintains an intentionally lean team structure, which reflects its selective client base and concentrated investment mandate. No additional office locations outside New York City have been publicly identified. In July 2023, the firm filed an SEC Form ADV indicating it manages pooled investment vehicles for its clients (per SEC, July 2023). Its structural differentiator is the co-investment model — the principals commit personal capital alongside each portfolio, aligning incentives tightly with client families. This architecture avoids fee drag typical of fund-of-funds and allows full transparency on deal terms.
