Knox Capital

Knox forms single-purpose vehicles around each transaction, raising committed equity from accredited investors, family offices, and smaller institutions on a deal-by-deal basis. Investors participate at the individual investment level rather than via a blind-pool drawdown structure. This approach allows limited partners to assess each opportunity separately and avoids the deployment-pressure timeline that defined-duration funds face. Thomas Sittema brought institutional SPV structuring capabilities from his tenure as CEO of CNL Financial Group, where the firm regularly formed programmatic investment vehicles.

Knox focuses on lower-middle-market companies with revenues typically between $10 million and $75 million. The firm pursues recapitalizations, growth equity rounds, and management buyouts in founder-owned or closely held businesses across enterprise software, financial services, healthcare services, and industrial technology. The strategy emphasizes control or significant minority positions that include board representation. Knox seeks situations where operational and governance professionalization, rather than pure financial engineering, drives value creation over an extended holding period.

Thomas K. Sittema, the firm's founder and managing partner, leads investment decisions. He previously served as CEO of CNL Financial Group, an Orlando-based alternative asset manager that raised and deployed over $20 billion across real estate, credit, and energy strategies. Sittema's background includes deep experience structuring private investment vehicles for individual and institutional participants. Knox operates with a lean investment team in Chicago, and its deal-by-deal capital model concentrates approval authority within a compact senior leadership group.

Knox itself does not make fund commitments — the firm deploys capital exclusively into direct control or significant minority investments in operating companies. From the investor side, the firm raises equity on a transaction-specific basis through single-purpose vehicles, meaning limited partners invest directly alongside Knox's principals in named portfolio companies. The firm does not operate as a fund-of-funds or allocate to third-party managers. This direct-deal orientation aligns with the independent-sponsor heritage of the Knox model.

Knox sources opportunities primarily through the Midwestern founder and intermediary networks that are accessible from its single Chicago office. The firm does not maintain satellite locations, concentrating origination effort on relationships with business owners, regional investment banks, and professional services firms operating in the Great Lakes and broader Midwest corridor. While Knox does not formally restrict itself to a geographic mandate, the partnership model and governance intensity of its investment approach favor proximity to portfolio companies. The home-services recapitalization completed in early 2024 reflects this regional sourcing posture.

Knox occupies a hybrid position between independent sponsor and conventional institutional private equity firm. Unlike most independent sponsors, the firm carries institutional-grade SPV infrastructure — investor qualification, compliance, reporting — developed from Sittema's tenure at a multi-billion-dollar asset manager. Yet Knox does not raise a blind-pool fund or charge management fees on undeployed capital, which separates the firm from traditional PE houses. Limited partners commit to specific deals rather than a fund program. This architecture gives Knox structural flexibility but also limits the firm to a smaller, transaction-specific capital base.
