Arnold Ventures
The Laura and John Arnold Foundation was founded in 2008 by John D. Arnold, former Centaurus Energy principal, and Laura Arnold. It restructured in 2019 as Arnold Ventures LLC while retaining its philanthropic mandate. The Arnolds signed the Giving Pledge in 2010. Arnold Ventures targets direct holdings and limited partner commitments in energy infrastructure, healthcare delivery, and education technology. Confirmed positions include Grid United LLC, Civica Rx, Fervo Energy, and Copper. The firm operates across the United States with emphasis on domestic policy outcomes and maintains a Washington, DC office for advocacy work. Asset classes span operating businesses, venture-stage companies, and select public equities such as Meta Platforms. The organization employs 189 professionals. Additional vehicles include the Action Now Initiative, a 501(c)(4) entity established in 2011 for policy advocacy. John Arnold joined the Meta Platforms board in 2024. Kelli Rhee has led as President and CEO since 2017. Arnold Ventures uses an LLC structure that permits both grant-making and direct investment in operating entities, distinct from traditional private foundations. This architecture supports ownership of Grid United at 100 percent through Centaurus Capital LP alongside philanthropic disbursements exceeding $2 billion since inception.
