Larry Page

Larry Page's family office Koop was converted from California and reincorporated in Delaware in late December 2025. He purchased $173.4 million in Miami real estate in January 2026. The moves came ahead of California's proposed wealth tax that would require billionaires worth over $1 billion to pay 5% of assets. Page, worth approximately $270 billion, would owe roughly $13 billion under the proposal.

Oceankind, founded by Larry Page's wife Lucinda Southworth in 2018, has spent more than $121 million funding marine science, technology, and conservation. Major grants include over $18 million to ClimateWorks for decarbonizing shipping and offshore wind, $7 million to Global Fishing Watch, $8.6 million to The Nature Conservancy, nearly $6 million to Natural Resources Defense Council, $6.4 million to Ocean Conservancy, and $4 million to Blue Ventures. The organization focuses on protecting oceans through technology and conservation.

In 2023 tax filings, the Carl Victor Page Memorial Foundation disclosed $66 million in grants to climate and environmental organizations - the first substantial direct grant disclosure in over a decade. This included two $23 million grants to the Stitching European Climate Foundation, $10 million to Brazilian Instituto Clima e Sociedad, $4 million to U.S. Energy Foundation, $3 million to Global Fishing Watch, and $1 million to Clean Slate Initiative. This marked a shift from the foundation's previous practice of routing 99.9% of grants through opaque donor-advised funds.

Between 2012 and 2022, Larry Page and Lucinda Southworth sent 99.9% of the dollars they granted from the Carl Victor Page Memorial Foundation to donor-advised funds. Over $1.2 billion was given to DAFs, making it impossible to track whether the money ever reached working charities. This was characterized as 'philanthropic sleight of hand' by critics.
