Caprock
Caprock was founded in 1999 by Matthew Weatherbie, initially as the family office for the Weatherbie family, before opening its doors to other ultra-high-net-worth families. The firm is headquartered in Boise, Idaho, with additional offices in Seattle, Newport Beach, Park City, and San Jose. Rather than cloistering its own family capital in a separate vehicle, Caprock pools its principals' wealth alongside that of its clients, creating a co-investment alignment that blurs the line between a single-family and a multi-family office. The firm manages over $10 billion in assets across private equity, venture capital, real assets, private credit, and hedge funds (per the firm, 2025). Caprock accesses these asset classes through a mix of direct co-investments, primary fund commitments, and secondaries, with a tilt toward partnerships that offer high alignment and transparent economics. The international mandate spans North America, Europe, and select emerging markets. Known positions and fund relationships span categories including buyout, growth equity, real estate, natural resources, and distressed debt. With a lean team distributed across its five offices, Caprock operates as an outsourced investment office for families that lack the scale to build a full in-house team. Its service model includes portfolio construction, manager due diligence, direct deal access, and consolidated reporting. The firm also assist clients with mission-aligned and impact strategies, integrating ESG and values-based screens where families request them. Caprock's structural differentiator is its origin as a single-family office that commercialized itself without retreating from co-investing. The Weatherbie family's capital remains embedded in the same strategies it recommends, making Caprock's investment committee a de facto principal-facing body rather than a disinterested advisory board. This posture is echoed in its stated commitment to "impact investing" and community-rooted operations, keeping core functions in Boise rather than a traditional coastal financial center.

Frequently asked questions
Who runs investment decisions at Caprock?
Gregory Brown serves as President and Chief Investment Officer, leading the investment team and chairing the investment committee. Chairman and CEO Matthew Weatherbie, who founded the firm as his family's office in 1999, remains actively involved in strategic allocation and client relationships. The investment committee includes both internal professionals and external advisors, with the Weatherbie family's own capital participating in the same strategies it recommends to clients.
Is Caprock structured as a single family office or a multi-family office?
Caprock is legally a multi-family office and registered investment advisor (RIA), but it retains the DNA of a single-family office. Founded to manage the Weatherbie family's wealth, it opened to outside families while keeping its principals' capital co-invested alongside client portfolios. This hybrid structure gives external families the same deal access and alignment typically reserved for single-family offices.
How does Caprock source proprietary deal flow?
Caprock sources through a combination of its deep general partner relationships, its participation in co-investment syndicates with peer family offices, and its own direct origination efforts. The firm's presence in Idaho and the Pacific Northwest provides entree to family-owned businesses, real assets, and natural resource opportunities that coastal platforms often overlook. Its five offices across the Western US extend its local-sourcing reach.
Does Caprock participate in fund commitments or only direct deals?
Caprock uses a full tool kit: primary fund commitments to institutional managers, direct co-investments alongside those managers, and secondary market purchases. The mix varies by client mandate, but the firm is known for aggressively pursuing co-investment rights in its fund relationships to reduce fee drag and increase concentration in its highest-conviction names.
What investment stages does Caprock typically target?
Caprock is agnostic to stage and instead focuses on manager quality and structural alignment. Its private equity portfolio spans early-stage venture, growth equity, middle-market buyouts, and special situations. In real assets, it covers development, value-add, and core-plus strategies across real estate, farmland, timber, and infrastructure.
Does Caprock maintain philanthropic structures, and how are they separated?
Caprock advises families on aligning philanthropic capital with their investment strategies, including the creation of donor-advised funds and private foundations. The firm integrates impact and ESG investing into its core platform rather than segregating it into a separate vehicle, though it stops short of requiring impact screens on client portfolios. Structures are legally distinct and client-directed, with Caprock serving as the investment advisor.
Where does the underlying wealth come from?
The founding wealth of Caprock originated with Matthew Weatherbie's family, though the specific industries that generated the family's capital have not been publicly disclosed in detail. Since opening the platform to outside families, the client base now represents wealth from a wide array of sources, including technology, real estate, manufacturing, and financial services, primarily concentrated in the Western United States.
