Branford Castle

What Branford Castle does

Branford Castle Partners is a New York-based private equity firm founded in 1986 by John K. Castle that operates as a control investor in North American lower middle-market companies. The firm targets businesses with up to $100 million of enterprise value and $2-15 million of EBITDA that hold leadership positions in niche industries, with sector focus spanning industrials and specialty manufacturing, consumer goods and services, value-added commercial distribution, business services, marine products and services, and healthcare. Branford Castle transitioned from a 30-year family office to an institutional private equity firm in October 2016 with the final close of its $116 million debut fund (Fund I) and subsequently closed Fund II in 2021.

The firm generates revenue primarily through management fees on committed capital and carried interest on successful portfolio exits, with Fund I achieving 47% gross IRR and 30% net IRR (top quartile per Preqin) and Fund II's first exit (Clean Solutions Group) returning approximately 103% of capital deployed, positioning the fund in the top decile per Cambridge Associates. Portfolio companies span pipeline safety equipment (GPT Industries' Pikotek flange isolation kits and IRT cathodic protection rectifiers), aviation component testing (Testek Solutions), electrical safety testing (Vitrek), aerospace and defense situational awareness (Hoffman Engineering), life sciences instrumentation (Lafayette Instrument with five add-ons including Sutter Instrument), dental services (Eastern Dental Management, 20 NJ locations), veterinary shock wave therapy (PulseVet, sold for $70.9M in 2021), wellness and massage equipment (Earthlite, ~20% global market share), longarm quilting machines (Handi Quilter, serving 15M+ enthusiasts), nonwoven filtration media (Fibrix Filtration), marine construction (Marine Floats), and roadway safety rumble strips (Surface Preparation Technologies, 49 states).

Deal sourcing runs primarily through an intermediary network with an industry-leading referral fee structure (4% proprietary, Lehman formula non-proprietary) supplemented by portfolio company-sourced add-on acquisitions. In March 2026, Marubeni Corporation made a significant investment in Branford Castle's new flagship fund and entered a strategic collaboration providing access to Marubeni's ~130 global offices. The firm is led by President & CEO John S. Castle, Managing Partner David Castle, Chairman John K. Castle, and Vice Chairman David Pittaway, with a senior team that includes Eric R. Korsten (rejoined May 2024), Ceon Francis, and Marilyn Yang (promoted to MD February 2026), operating from headquarters in New York City and a regional office in Boca Raton, FL.
