1010 Holdings

Kent Thiry and his wife Denise O'Leary founded 1010 Holdings in 2012, following his nearly two-decade run as CEO and Chairman of DaVita. Thiry took the company from near-bankruptcy to a Fortune 500 leader in kidney care, generating the core wealth the family office now manages. The firm's roots sit firmly in the operational rigor Thiry applied at DaVita — 1010 does not function as a passive allocator spreading capital across outside funds, but as a direct investment engine targeting businesses where Thiry's governance and operating playbook can compound value over decades. The portfolio spans venture, growth equity and buyout positions, concentrated in healthcare services, enterprise software, and fintech. 1010 has backed companies at the intersection of technology and regulated industries — a lane that maps directly to Thiry's experience scaling a Medicare-dependent, compliance-heavy business. Known investments include Collective Health, the employer health-benefits platform, and Guild Education, the workforce-education marketplace that reached a $4.4 billion valuation in 2022 (per Bloomberg, 2022). The firm invests nationally from its Colorado base, with an additional presence in Menlo Park to maintain proximity to Bay Area venture and talent networks. The firm operates with a lean team built around Thiry as investment decision-maker. O'Leary, a former Medtronic board member and venture investor, brings independent healthcare and technology governance experience to the portfolio. The office does not market itself, does not publish deployment figures, and does not solicit third-party capital — a posture consistent with a single-family office that prizes permanence over scale. Its philanthropic work, conducted through the Thiry-O'Leary Foundation, channels resources into education and civic initiatives, including a $5 million election-integrity grant program launched in 2022 (per the foundation's public filings). 1010's structural distinction rests on a founder-operator model uncommon among family offices of comparable wealth tier. Thiry did not hand the keys to an outside CIO or to a platform of fund relationships — he runs the investment process directly, applying the same capital-allocation discipline and stakeholder-governance framework he wrote into DaVita's operating manual. That operating DNA, combined with indefinite holding periods, positions 1010 as a competitor to growth-stage institutional firms while retaining the patience and decision velocity of a single-family balance sheet.

Frequently asked questions

Who makes investment decisions at 1010 Holdings?

Kent Thiry serves as the central decision-maker for 1010 Holdings, bringing the same operator-first lens he used as CEO of DaVita. His wife and co-founder, Denise O'Leary, contributes her own healthcare governance and venture experience but does not run the day-to-day investment process. The firm does not delegate portfolio construction to an external CIO or investment committee of hired managers.

How does 1010 Holdings source its deals?

The firm sources through Thiry's deep network across healthcare services, enterprise technology and corporate governance circles. Thiry's tenure on boards such as McKesson and his public-company CEO track record open doors to founder-led businesses in regulated industries. 1010 does not operate a scouting platform or rely on intermediaries for primary deal flow.

Is 1010 Holdings a venture capital firm or a family office?

1010 Holdings is a single-family office, not a venture capital firm. It deploys Kent Thiry's personal capital, not third-party limited partner funds, and does not operate with a fixed fund lifecycle or a mandate to return capital on a standard venture-fund timeline. Its willingness to hold assets indefinitely — including control positions — distinguishes it from institutional venture firms.

Does 1010 participate in fund commitments or only direct deals?

1010 is overwhelmingly a direct investor, consistent with Thiry's preference for control and direct governance influence. While the firm could make selective fund commitments to access specific managers or geographies, public record indicates its primary mode is direct equity — growth-stage, buyout and venture positions on its own balance sheet.

What is 1010's relationship with DaVita?

1010 Holdings is entirely separate from DaVita Inc. The wealth originated from Kent Thiry's tenure as CEO and Chairman of DaVita, but the family office is a distinct entity with no structural or investment ties to the public company. Thiry stepped down as DaVita's Executive Chairman in 2023 and is not involved in the company's day-to-day management.

How is philanthropic activity structured at 1010 Holdings?

Philanthropy is conducted through the Thiry-O'Leary Foundation, a separate legal entity from the investment office. The foundation focuses on education, civic engagement and election integrity. It maintains its own governance and grant-making processes, ensuring clear separation from the family-office balance sheet and investment operations.

What is 1010's known posture on co-investments with external managers?

1010 does not actively publicize co-investment activity, but as a single-family office it can participate opportunistically alongside like-minded long-duration capital partners. The firm's control-oriented mindset and permanent capital likely make it a selective co-investor that prefers situations where its operational input adds measurable value rather than passive syndicated rounds.
