Prime Group Holdings is a vertically integrated private equity real estate firm founded in 2013 that focuses on acquiring, managing, and operating self-storage assets across the United States, Canada, and the Caribbean. The firm has evolved into one of the largest private owners of self storage, with a portfolio encompassing more than 400 assets across 28 U.S. states, three Canadian provinces, and the Caribbean islands, representing over 30 million rentable square feet. The company operates its self-storage facilities under the Prime Storage brand name. Prime Group employs an off-market, grassroots sourcing method to identify acquisition opportunities in highly fragmented commercial real estate and digital infrastructure asset classes. This approach enables the firm to implement professional operational protocols and leverage economies of scale. The firm's investment strategy targets properties that can be aggregated into a large, stabilized, well-managed portfolio through one-by-one acquisitions. Prime Group operates a series of investment funds, including Prime Storage Fund III, which was reported as the largest dedicated self-storage fund ever raised. As of March 2026, the firm has raised $3.75 billion in capital and employs over 700 people.
