Nine years after he left a Harrogate sixth form college two days into his A-levels, 25-year-old James Dacombe holds a stake in a British chip company that publicly filed shareholding data valued at about £946M ($1.27B).

The estimate follows a $312M (£232M) Series B round for Olix, the London inference chip designer he founded in 2024. Olix announced the financing on 3 August at a valuation of $3.3B (£2.5B). That is roughly triple the $1B mark set in February by a $220M (£163M) Series A.
