What Littlejohn & Co., LLC does
Littlejohn & Co., LLC is a U.S. middle-market private investment firm founded in 1996 and headquartered in Greenwich, Connecticut. The firm invests across three complementary strategies: Private Equity, Credit through its Wellfleet Credit Partners platform (approximately $4.2B AUM), and Capital Solutions, with total regulatory assets under management of approximately $9B as of mid-2026. Its investment focus is on industrial and services companies in North America, with portfolio activity spanning modular buildings, rail services, utility engineering and consulting, building code compliance, and industrial distribution.
The firm employs 70+ professionals, including 45+ investment professionals, with an average partner tenure of approximately 20 years. Recent platform acquisitions include Milrose (2026), GDS Associates (2026), 80/20 (2026), RailPros (2025), and Sunbelt Modular (2024), while realizations have included the agreed sale of Hiller (2026) and prior exits of PlayPower, PatientPoint, and Motion Recruitment. Notable historical realizations include HydroChemPSC ($1.25B, 2021) and Kaman Distribution ($1.3B sale announced, 2022).
Littlejohn generates revenue from management fees on committed fund assets and from carried interest on realizations, with the latter creating lumpy revenue tied to exit timing. Limited-partner relationships and institutional fundraising are core to revenue durability. The firm completed a leadership succession in 2026, elevating Brian Michaud to Managing Partner, Michael Klein to Chairman, Brian Ramsay to Vice Chairman, and adding Shant Mardirossian as Chief Operating Officer.
