We get asked occasionally why we incorporated in the UK rather than Delaware. Three reasons.
Data residency. Building a product where customer data sits in EU/UK regions by default is much easier when the company itself is UK-based. We considered Ireland; we picked Bournemouth's graduates and London's lawyers.
Attitude towards research. UK academic AI has a long quiet tradition of symbolic and hybrid approaches — including some of the work this engine descends from. Recruiting from that tradition is easier when we're physically nearby and the conversation is in person.
Boring infrastructure. UK Companies House is fast and cheap. HMRC is fine. The visa rules for hiring research engineers are slightly less hostile than they were two years ago. London has more NHS-trained AI ethicists per capita than anywhere else we considered.
It's not a strategic move; it's a pragmatic one. Calm software benefits from calm infrastructure. The UK isn't perfect, but for what we're doing it's the right place.
