Spieker Partners

Spieker Partners was formed in 2001 after Ned Spieker sold his Spieker Properties REIT to Equity Office Properties for $7.2 billion, generating one of the largest commercial-real-estate fortunes on the West Coast (per the firm and public record). The office operates from Atherton, California, where Ned and his family manage assets that still tilt heavily toward property — visible in the multi-thousand-unit apartment portfolio Spieker Companies controls across Silicon Valley, the Central Valley, and Southern California. His brother Tod Spieker runs the daily operations of that property arm, while Ned's son, Ned Spieker III, has taken the Managing Partner role at the main investment entity. The firm's real estate holdings are concentrated in California multifamily and senior-living developments. Properties include Stoneridge Creek in Pleasanton, Reata Glen in Rancho Mission Viejo, Wisteria at Warner Center in Woodland Hills, and Varenna at Fountaingrove in Santa Rosa (per public record). Outside California, the family owns The Village at Penn State, a student-housing property. On the venture side, Spieker Partners makes direct early-stage startup investments and has disclosed an agriculture vertical consisting of California farmland holdings. The dual mandate — institutional-quality real estate management alongside early-stage venture — is unusual for a single-family office and reflects Ned Spieker's continued hands-on involvement. Beyond direct investing, the family's influence extends through significant philanthropic commitments to the University of California system. Ned and Carol Spieker have donated more than $30 million to UC Berkeley, where they serve on the UC Berkeley Foundation board, and Tod Spieker made a landmark $50 million gift to UCLA's undergraduate business program in 2023 (per UCLA, 2023). The Spieker Family Foundation serves as the family's primary charitable vehicle, while Ned also sits on the board of the Glaucoma Research Foundation. Team size and total deployment are not publicly disclosed. What distinguishes Spieker Partners structurally is its unwillingness to separate the family's operating business from its investment activity. Unlike peers who sell a company and immediately outsource management, the Spiekers retained direct control of a substantial property portfolio — making the office a hybrid of operating company, venture investor, and traditional family office. The next generation, through Ned Spieker III, is now integrating earlier-stage technology exposure alongside the legacy real estate base.

Frequently asked questions

Who runs investment decisions at Spieker Partners?

Ned Spieker III serves as Managing Partner of the investment entity. His father, Warren E. "Ned" Spieker Jr., founded the firm and remains the ultimate decision-maker, while Richard "Tod" Spieker runs the Spieker Companies property portfolio. The firm does not publicly name additional investment committee members.

How is Spieker Partners related to Spieker Properties?

Spieker Properties was the West Coast office REIT Ned Spieker founded and took public in 1993. He sold it to Equity Office Properties Trust — controlled by Sam Zell — in a $7.2 billion deal that closed in 2001. Spieker Partners is the family investment vehicle formed with those proceeds and has no continuing relationship with the original REIT.

Does Spieker Partners invest in funds or only direct deals?

The firm's known posture emphasizes direct ownership — real estate assets through Spieker Companies and direct startup stakes in its venture practice. There is no public evidence of a fund-of-funds program or significant external GP commitments, though allocations outside real estate and venture remain undetailed.

What is Spieker Partners' agricultural exposure?

The family holds agricultural land in California, though specific acreage and crop coverage are not disclosed. This sits alongside their multifamily and senior-living real estate portfolio and represents a diversification from their urban-property roots.

Is Spieker Partners structured as a single-family office?

Yes. The firm manages capital exclusively for the Spieker family. It operates from Atherton, California, with overlapping leadership between the investment office and the operating property company, and does not solicit or accept outside capital.

How does the Spieker Family Foundation relate to the investment office?

The Spieker Family Foundation is the family's primary philanthropic vehicle, responsible for major gifts to UC Berkeley and UCLA. It is legally separate from Spieker Partners and Spieker Companies, though Ned Spieker, Tod Spieker, and their spouses serve as the primary donors and directors.

What is Spieker Partners' venture investment approach?

The firm targets early-stage startups directly, with a preference for technology and innovation companies. It has not publicized dedicated fund vehicles, instead making investments off its own balance sheet. The practice sits alongside the larger real estate portfolio as a growth-oriented sleeve.
