Frequently asked questions
What happened to Rockspring Property Investment Managers?
Rockspring Property Investment Managers, the UK-headquartered pan-European real estate fund manager, was acquired by Patrizia AG in 2017. The transaction brought Rockspring's portfolios and team under the Patrizia brand, and the Rockspring name ceased to be used for the European institutional real estate platform (per Patrizia AG, 2017). The Cambridge-based technology investment activities continued separately through the founders' angel investing vehicle.
Is Rockspring Capital in Houston the same firm as Rockspring in Cambridge?
They share a name and some founder connections but operate as independent entities. Rockspring in Cambridge, founded by David Gammon and Richard Plummer, historically managed European real estate funds and early-stage technology investments. Rockspring Capital in Houston, led by Jim McAlister IV, acquires and develops land tracts across Texas growth corridors. No single parent company consolidates the two operations.
Does Rockspring invest in technology startups?
Yes, through the Cambridge Angels network, where founder David Gammon is a longtime member. The group participates in seed-stage syndicates, with co-investors that have included Jaan Tallinn, the co-founder of Skype. These investments are separate from the real estate activities and are made on the founders' own account rather than through a dedicated fund vehicle.
Where does Rockspring own real estate?
The UK platform's historical portfolio included office, residential, and retail assets in the UK and Germany, such as 103 Colmore Row in Birmingham, The Forum residential development in Southside Birmingham, and the Flora-Park Shopping Centre in Magdeburg. The Houston arm holds land and commercial properties across Texas, including tracts in Katy, San Antonio's Westover Hills, and a mixed-use site near the Alamodome.
Who makes investment decisions at Rockspring Capital?
Jim McAlister IV, as President and CEO of Rockspring Capital in Houston, leads the Texas land-assembly and commercial real estate investment decisions. The Cambridge group's early-stage technology investments are made by David Gammon individually and through the Cambridge Angels syndicate, where investment decisions are made collectively by participating members.
