Craig and Susan McCaw Foundation

The Craig and Susan McCaw Foundation was established in 1998, four years after the sale of McCaw Cellular Communications to AT&T — a landmark deal that reshaped the US wireless industry. Craig McCaw had built the company into the nation's largest cellular network before the acquisition, and the foundation channels a portion of that wealth into grantmaking. Susan McCaw, who served as US Ambassador to Austria from 2005 to 2007 under President George W. Bush, brings a diplomatic and investment banking background to the foundation's governance. The couple are signatories of The Giving Pledge, committing the majority of their wealth to philanthropy. The foundation maintains a three-pronged grantmaking focus: expanding education access, supporting international economic development, and advancing environmental conservation. While the foundation does not publicly disclose granular investment holdings or grantee lists, its tax filings and public record indicate a portfolio that spans direct charitable grants, mission-related investments, and a traditional endowment allocation. The McCaw family's broader investment activity — historically encompassing venture capital, distressed debt, and private equity through family office structures — suggests an investment committee comfortable with alternative assets. Geographic emphasis extends from the Pacific Northwest, where the family maintains deep roots, to international programs in developing economies. With an estimated endowment of $10 million to $50 million, the foundation is modest relative to the McCaw family's total wealth, much of which resides in discrete family office entities and direct holdings. The foundation does not maintain a large professional staff and operates without satellite offices. Susan McCaw serves as Vice Chair of the Hoover Institution, and Craig McCaw sits on its Board of Overseers — institutional affiliations that reinforce the foundation's intellectual leanings. The McCaws also maintain philanthropic structures including the Susan Rasinski McCaw Foundation and The Com Family Foundation, creating a distributed architecture for their charitable giving. The foundation's structural differentiator is its integration with a family office complex that blurs the line between philanthropic mission and investment pragmatism. Rather than operating as a standalone grantmaking institution, the Craig and Susan McCaw Foundation functions as one node in a network that includes direct investments, a significant collection of hard assets — aircraft, yachts, classic cars, and extensive real estate across Washington, California, and British Columbia — and affiliations with organizations like the Council on Foreign Relations. This architecture allows the foundation to remain lean while the family's broader resources influence its capacity to fund and scale initiatives.

Frequently asked questions

What is the source of wealth behind the Craig and Susan McCaw Foundation?

The foundation's endowment derives from the telecommunications fortune Craig McCaw built through McCaw Cellular Communications, which he sold to AT&T in 1994 for $11.5 billion. Susan McCaw, a former investment banker at Robertson Stephens and later US Ambassador to Austria, co-directs the foundation's philanthropic strategy. The couple signed The Giving Pledge in 2011, publicly committing to donate the majority of their wealth.

How does the foundation's investment activity differ from the broader McCaw family office?

The foundation itself maintains a modest endowment estimated at $10 million to $50 million that supports its grantmaking programs. The broader McCaw family wealth, however, is managed through discrete family office entities that have historically invested across venture capital, distressed debt, private equity, and real estate. The foundation does not publicly disclose whether it co-invests alongside these family office vehicles, though its tax filings indicate a conventional grantmaking and mission-investment structure.

What is the foundation's geographic focus?

Grantmaking concentrates on three areas: expanding education access, international economic development, and environmental conservation. Geographically, the foundation directs resources to programs in the Pacific Northwest — where the McCaws maintain their primary residence in Hunts Point, Washington — as well as international initiatives in developing economies. The McCaws' personal real estate holdings span Washington, California, and British Columbia, reflecting a bi-national Pacific orientation.

Are Craig and Susan McCaw actively involved in the foundation's governance?

Yes. Craig and Susan McCaw serve as the foundation's directors and primary decision-makers. Susan McCaw's additional roles — Vice Chair of the Hoover Institution and member of the Council on Foreign Relations — inform the foundation's intellectual and policy orientation. Craig McCaw sits on the Hoover Board of Overseers, while both engage with allied philanthropic vehicles including The Com Family Foundation.

Does the foundation accept unsolicited grant proposals?

The foundation does not publicly invite unsolicited proposals and does not maintain a public-facing grant application portal. Grantmaking appears to follow a curated approach consistent with the McCaws' existing philanthropic and professional networks. Organizations seeking funding would likely need an introduction through the foundation's established advisory or institutional channels.

What is the relationship between the Craig and Susan McCaw Foundation and The Com Family Foundation?

The Com Family Foundation is a separate philanthropic entity affiliated with the McCaw family, adding a layer of complexity to their charitable architecture. Amit Mehta serves as Vice President of The Com Family Foundation, acting as a connective figure between the family's various philanthropic structures. The foundations appear to operate with overlapping governance but maintain distinct grantmaking programs and fiduciary responsibilities.

Has the foundation publicly reported its grantmaking totals?

The foundation files an annual Form 990-PF with the IRS, which reports grants paid, investment income, and endowment assets. Those filings are publicly accessible and detail grant recipients and amounts, though the foundation itself does not issue press releases or annual reports summarizing aggregate grantmaking figures. Researchers can retrieve these records through standard nonprofit databases.
