What Southfield Mezzanine does
Southfield Mezzanine is a private investment firm providing mezzanine financing to lower middle-market businesses across the United States. Founded in 2002 as Southfield Capital (originally a private equity firm), it launched its dedicated mezzanine strategy in 2013 by raising an inaugural fund structured as a Small Business Investment Company (SBIC). The firm targets U.S.-based businesses with at least $3 million of EBITDA, deploying $5–20 million per platform through unitranche debt, subordinated debt, preferred equity, and common equity instruments, with the ability to scale ticket size via co-investment partners. Southfield is industry-agnostic and supports acquisition financings, growth financings, recapitalizations, and buy-and-build strategies for both private-equity-sponsored and non-sponsored management teams.
The firm serves three primary customer segments: lower middle-market operating companies, private equity sponsors seeking gap financing in the capital stack, and founder-owned businesses pursuing liquidity or growth capital. It generates revenue through management fees on institutional LP commitments to its SBIC-licensed funds, recurring interest income from mezzanine debt instruments, and returns from minority equity stakes. The firm currently invests out of Fund III, having progressed from the upsized $150 million Fund I through Fund II, and operates from Greenwich, Connecticut (headquarters) and Beverly Hills, California.
Southfield Mezzanine's deal flow is sourced through a relationship-based model anchored in long-standing partnerships with private equity sponsors including Century Park Capital Partners, RTC Partners, Graycliff Partners, Calvert Street Capital Partners, Corridor Capital, HCAP Partners, Sky Peak Capital, Taglich Private Equity, Tamarix Equity Partners, and others. The portfolio spans more than 40 companies across healthcare services, aerospace and defense manufacturing, business services, restaurant franchises, software integration, non-destructive testing, elevator services, and rail/industrial services. The firm positions itself on responsiveness (initial feedback within 48 hours), certainty of closure, and flexible deal structuring, supported by a lean team of 11–50 employees.
