About Ballmer Group
Ballmer Group is the family office of former Microsoft CEO Steve Ballmer and his wife Connie Ballmer, legally structured as Ballmer Giving LLC and based in Bellevue, Washington. Founded in 2015, shortly after Steve retired from Microsoft, it is best characterized as a philanthropic investment company: its stated purpose is to advance economic mobility, and its "investments" are overwhelmingly grants and program-related commitments rather than conventional venture or private-equity deals.
Grantmaking is concentrated in three core geographies — southeast Michigan, Washington state, and Los Angeles County — alongside national commitments in early learning, education, housing, and criminal justice. On the personal-investment side, Steve Ballmer has stated that more than 80% of his portfolio remains in Microsoft stock, with the balance largely in broad index funds.
