The Gladstone family of companies was founded by David Gladstone, starting with the establishment of predecessor investment entities and expanding over decades into a prominent group of publicly traded financial funds and real estate investment trusts. This included launching Gladstone Capital, Gladstone Commercial, Gladstone Investment, and eventually Gladstone Land Corporation in the early 2010s to focus specifically on agricultural real estate acquisition and leasing. Over the years, the organization has grown from a boutique private equity and debt provider into a multi-billion-dollar publicly traded family of funds managing diverse portfolios across America.
