DSIT named seven companies in the Sovereign AI Unit's first cohort on 16 April: Callosum took an equity investment, while Prima Mente, Cosine, Cursive, Doubleword, Twig Bio, and Odyssey each received up to one million GPU hours plus ten fast-tracked visas.
Every selected firm sits at the infrastructure or model layer, with no consumer AI companies chosen. This turns the £500m policy announcement into named bets for the first time, anchoring founder expectations on sector mix and compute allocation.
