The Thomas and Stacey Siebel Foundation
Thomas and Stacey Siebel established their eponymous foundation in 1996, the same year Siebel Systems went public. The wealth originates from Siebel Systems, which dominated the customer relationship management market before a $5.8 billion acquisition by Oracle in 2006. The foundation operates from Redwood City, California, with a grantmaking focus on homelessness, at-risk youth, education, public health, and alternative energy solutions. The foundation's known grantmaking vehicles include the Siebel Scholars program, which funds graduate students at top universities in business, computer science, and bioengineering, and the Montana Meth Project, a large-scale substance-abuse prevention effort. While its public filings describe a short-term investment fund, the foundation does not disclose specific portfolio positions. Its geographic footprint centers on California and Montana, where the Siebels maintain significant real estate and agribusiness operations, including the Dearborn Ranch near Wolf Creek and the N Bar Ranch in Grass Range. Total assets are not publicly disclosed by the foundation. The foundation also overlaps with Siebel's other ventures, including the Siebel Scholars Foundation and his role as a director of the Hoover Institution. Thomas Siebel is an elected member of the American Academy of Arts and Sciences. The foundation's structural distinctiveness lies in its deep integration with the Siebel family's Montana land holdings and operating ranches, blending traditional philanthropy with large-scale agribusiness management. This convergence of a Silicon Valley fortune with a substantial physical-asset footprint in the Northern Rockies creates an unusual capital base not typically seen in tech-founder foundations.

Frequently asked questions
Who runs investment decisions at The Thomas and Stacey Siebel Foundation?
The foundation's structure centers on the family itself. Thomas M. Siebel and his wife Stacey Siebel are the named founders, and investment and grantmaking decisions likely flow through a lean family-office model rather than a large external investment committee. The foundation does not publicly list independent investment staff.
How does The Thomas and Stacey Siebel Foundation source its grantmaking pipeline?
The foundation appears to originate grants through its own programs like the Siebel Scholars and Montana Meth Project rather than reactive applications. The Siebel Scholars program is embedded in specific partner universities, creating a closed-network pipeline for identifying talent. No external grant application portal was found.
Is the foundation structured as a traditional endowment, or does it operate more like a family office?
It functions as a private foundation with a lean operational footprint, not a multi-staff endowment. The foundation's tax status and grantmaking behavior align with a founder-led vehicle where strategy is tightly held. The Siebels' Montana ranches are held as separate family assets, not under the foundation.
What is the foundation's known posture on investment transparency?
The foundation does not publicly disclose its investment portfolio, asset allocation, or specific securities held. Its IRS Form 990-PF data may offer limited aggregated balance-sheet information, but direct-investment details are not publicly promoted.
Does the foundation maintain philanthropic structures separate from the Siebel Scholars program?
Yes. The Montana Meth Project operates as a distinct initiative focused on substance-abuse prevention, and the foundation's broader grants target homelessness, education, and alternative energy. The Siebel Scholars Foundation is a separate but related vehicle that funds graduate fellowships.
Which sectors does the foundation explicitly avoid?
While no explicit negative sector screen is published, the foundation's stated priorities suggest an affirmative focus on education, public health, the environment, and solutions for homelessness and underprivileged communities. There is no public indication of investments in extractive industries or defense technology.
Where does the underlying wealth originate?
The majority of the wealth derives from Thomas M. Siebel's founding of Siebel Systems, a pioneer in enterprise CRM software. Oracle Corporation acquired Siebel Systems for approximately $5.8 billion in 2006, creating the liquidity event that largely capitalizes the foundation.
