Oak Hill Capital Partners

What Oak Hill Capital Partners does

Oak Hill Capital Partners is a middle-market private equity firm founded in 1986 and headquartered in Stamford, Connecticut, with additional offices in New York and Menlo Park, California. The firm pursues theme-based investing across two core sectors — Services and Digital Infrastructure — through growth equity, buyouts, and recapitalizations. Since inception, Oak Hill has deployed more than $23 billion of capital across 110+ transactions, operating under an institutionalized, systematic investment playbook led by Managing Partner Tyler Wolfram.

The firm's current portfolio reflects an aggressive thematic consolidation strategy, particularly in U.S. fiber-to-the-home and broadband infrastructure (22 disclosed broadband investments including Greenlight Networks, Wire 3, Hunter Communications, Omni Fiber, IdeaTek, Socket Telecom, GoNetspeed, FirstLight, and others), with additional platforms in home services (Guild Garage Group), insurance brokerage (IMA Financial Group, valued at $4.0 billion in a 2026 recapitalization), environmental consulting (Trinity Consultants), and European data centers (Global Technical Realty, co-invested with KKR for $1.9 billion). In 2026, Oak Hill also formed a 50/50 joint venture with T-Mobile combining GoNetspeed and Greenlight Networks for approximately $2 billion.

As a private equity firm, Oak Hill's revenue is derived from management fees and carried interest on its investment funds, with limited partner capital sourced through direct institutional relationships. The firm has raised approximately $20 billion cumulatively since founding, with Wafra Inc. (Kuwait-backed) having acquired a minority stake from Jefferies Financial Group in 2022. Oak Hill does not develop technology products; its competitive position rests on sector specialization, capital scale, and a four-decade operating track record.

• New Mountain Capital: Growth-oriented middle-market private equity firm with comparable sector focus in services and infrastructure. Co-invested with Oak Hill in IMA Financial Group, making it a direct transactional peer and capital partner.
