Northampton Capital

What Northampton Capital does

Northampton Capital Partners is a private alternative asset manager focused on infrastructure investments in the energy, digital, and other critical infrastructure sectors. The firm is headquartered in New York and operates as a boutique manager deploying institutional capital into infrastructure assets, with its most significant disclosed initiative being a 2026 joint venture with Olympus Power called Winslow Power, formed to acquire and operate conventional power generation assets in the Northeast United States. Through Winslow Power, the firm controls 752 MW of combined capacity across three plants acquired from a Vistra Corp subsidiary: the 541 MW Casco Bay combined cycle facility in Veazie, Maine, a 108 MW dual fuel turbine in Croghan, New York, and a 103 MW dual fuel turbine in Solvay, New York.

The firm earns revenue through two standard alternative asset management streams: recurring asset management fees on deployed capital and carried interest or performance fees tied to investment outcomes. Distribution is conducted exclusively through direct institutional sales targeting qualified institutional investors, family offices, and high-net-worth individuals, with investor relations handled via a dedicated email ([email protected]) and phone contact rather than broad-based marketing. The four named founders — Geoffrey Strong (CEO), Don McCarthy (COO), John MacWilliams (Partner), and Scott McBride (Partner) — appear to control and operate the firm without disclosed institutional backing or parent company affiliation. The product portfolio is investment-vehicle-based rather than technology-based, and the firm does not maintain a unified software platform or proprietary technology stack.
