Founded in 2005, Bezos Expeditions is Jeff Bezos's family office, managing an estimated $12bn in direct investments and personal holdings separate from his Amazon stake and separate from Blue Origin, the space company he funds directly. It has backed more than 90 companies since inception, with 15 unicorns and 13 IPOs among its exits, including early stakes in Google, Airbnb and Uber.
Its CuspAI stake, first reported in June when Bezos Expeditions signed a term sheet alongside Kleiner Perkins , closed as part of the Cambridge company's $450m Series B on 20 July 2026, when CuspAI also unveiled a 45-partner AI Materials Foundry coalition . The firm's broader portfolio spans deep technology globally, including Physical Intelligence in robotics, Anduril Industries in defence and Synchron in brain-computer interfaces.
CuspAI is one of a small number of UK-founded deep-tech companies the family office has chosen to back directly rather than through a fund manager, a structure that means any future dividends or exit proceeds from the Cambridge company flow to a US private vehicle rather than to British capital.
