Rockfence Investment Management

Rockfence Investment Management

Rockfence Investment Management was founded in 2007 by Tommy Brigham, a former investment banker who previously co-founded the Birmingham-based investment firm Brigham & Company. The office manages capital generated from the sale of that earlier firm, structuring itself as a single-family office with a lean professional team. Larry L. DeRieux serves as Chief Financial Officer. The firm's investment strategy spans multiple asset classes, including real estate, private credit, hedge funds, and infrastructure with a growing focus on energy transition and renewables. Rockfence participates in both direct co-investments and fund commitments alongside external managers. The office has a particular focus on Southeastern US real estate assets and has disclosed positions in private credit vehicles targeting middle-market loans. Geographic deployment is concentrated in North America, with selective exposure to European infrastructure deals. Rockfence maintains a small, centralized team based in Birmingham with no additional offices disclosed. The office does not operate a separate philanthropic foundation under the Rockfence name. Recent activity includes a 2024 commitment to a renewable energy infrastructure fund targeting solar and battery storage projects in the Southeastern US (per public record, 2024). The team size is estimated at fewer than 15 professionals. Unlike many single-family offices that remain fully private, Rockfence has a disclosed organizational structure with named principals and a defined investment mandate. The office operates with a hybrid model — partly direct investing in real assets and partly allocating to external managers across credit and hedge fund strategies. This dual approach allows the family to maintain operational control over direct holdings while accessing broader markets through third-party funds.
