About Mongo Holdings
Mongo Holdings is the private investment entity of the Atlanta, United States single family office of Barry and Gail Bierenbaum. Mongo Holdings specializes in investing across real estate, private loans, digital assets, private equity, venture capital, and real assets. The family's wealth derives from Mountain Express Oil, a fuel wholesale distribution business founded in 2000 by Barry and Gail Bierenbaum that grew and expanded into real estate holdings, convenience stores and quick-serve restaurants. Barry Bierenbaum sold his stake and left the company in 2020. The office's assets are estimated by a third party at roughly $100M. Following Mountain Express's later Chapter 7 bankruptcy, a trustee stated that Mountain Express founder Barry Bierenbaum siphoned over $130 million, mainly from selling his stake in the company in 2020 — an allegation being litigated in federal court in Atlanta.
