## About

The Rauner Family Foundation was established in 1995 by Bruce and Diana Rauner as a 501(c)(3) philanthropic vehicle. Bruce Rauner's wealth originates from GTCR, the private equity firm he co-founded and chaired, which pioneered a partnership model of acquiring and transforming companies in fragmented industries. Diana Rauner, a child psychologist, serves as vice president of the foundation and is president of Start Early, a nationally recognized early childhood nonprofit. The foundation's grant-making reflects both principals' professional biographies — rigorous, data-driven, and concentrated on structural reform rather than general operating support. Strategy is weighted toward venture philanthropy in education, direct-service health and human services, and environmental conservation. The foundation does not publish a grant database, but its IRS filings show longstanding support for charter school networks, teacher-training pipelines, and policy advocacy organizations pushing accountability metrics in Illinois public schools. Beyond education, the Rauners have funded veterans' services, Jewish communal institutions, and land conservation easements through the Montana Land Reliance. This is high-conviction, concentrated giving — fewer, larger grants designed to shift systems rather than sustain programs indefinitely. Scale is modest by private foundation standards, with an asset base estimated at $50–$100 million (Altss estimate). The foundation's grant-making budget typically runs in the single-digit millions annually, consistent with a foundation of that size. The Rauners maintain significant personal assets outside the foundation, including residential properties in Winnetka, Manhattan, Montana, and Key Largo, plus minority stakes in the Chicago Bulls and Pittsburgh Steelers through separate family entities. Bruce Rauner's tenure as Illinois governor (2015–2019) brought unprecedented public visibility to the family's education philanthropy, as he personally funded charter advocacy and school-choice initiatives alongside his official policy efforts. Structural differentiator: the foundation functions as the family's primary institutional philanthropic arm but operates entirely apart from the Rauners' personal investment vehicles and GTCR commitments. Unlike family offices that co-mingle grant-making with impact investing, the Rauner Foundation's 990 filings show a clean line between foundation grant disbursements and the family's private investment activity. This governance separation, combined with Bruce Rauner's high-profile political career, makes the foundation unusually transparent in its charitable purpose while remaining almost entirely opaque about its investment management — a deliberate posture that mirrors the discretion of a traditional Midwest industrial fortune.

## Questions

### How is the foundation related to GTCR?

The foundation is entirely separate from GTCR, the private equity firm Bruce Rauner co-founded in 1980 and chaired until 2012. GTCR is not a funding source for the foundation; the Rauners' personal wealth, generated through GTCR's carried interest and co-investment returns, funds foundation grant-making independently.
