When his appointment as chair of the Sovereign AI Unit was announced on 21 November 2025, James Wise set out how he would handle his other job. "It will not change my role at Balderton, although any possible conflicts will be published well in advance on the Department's website," he wrote1. Wise is a partner at the venture firm Balderton Capital, and has chaired the Unit since it launched on 16 April 2026. The Unit can commit up to £500 million in equity, and took a position in CuspAI in July.
That undertaking was checked at source on 21 September rather than through a search engine. The Unit's own site carries no governance material. The gov.uk organisation pages for the Department for Business and Trade, the Department for Business, Innovation, Science and Trade and the Department for Science, Innovation and Technology, including that department's own governance page, name neither the Unit nor its chair. The DSIT Annual Report and Accounts 2025-26 runs two conflicts-of-interest sections and Wise appears in neither2. The Unit was delivered by a department abolished in July 2026, a machinery change this topic leaves to its own story, which may explain where such a page would now sit.
One distinction decides how much any of that weighs. Wise is not a senior civil servant and he does not sit on a departmental board, so neither of those two registers is one he was required to appear in. No rule obliged him to publish anything. He gave an undertaking, and the public record does not yet show it discharged. An undertaking outstanding and a duty breached are different things, and a reader should hold them apart.
Nothing here alleges wrongdoing by Wise or by the Sovereign AI Unit. Dame Chi Onwurah has asked government to explain the conflict-of-interest standard applied at a state research funder. Whether the same standard applies to a state investor writing equity cheques into the sector its chair invests in professionally has not been put to anyone.
