British Business Bank commits £10M to Odyssey Ventures to back UK AI and deeptech founders

The British Business Bank has decided to back Odyssey Ventures with a £10 million commitment, funneled through its Regional Angels Programme and made alongside Odyssey's own early-stage vehicle, Odyssey Discovery I. It's a targeted move, not a scattershot one — the money is meant to plug a very specific hole in the UK startup pipeline: the gap between brilliant early ideas and the capital needed to compete globally.

That gap is not small. Europe's funding shortfall relative to the US topped $375 billion between 2015 and 2024, according to figures cited alongside the announcement, and UK and European early-stage companies routinely get valued well below their American counterparts. So even when the UK produces strong AI and deeptech founders — and the country is described as leading Europe on this front — those founders often find themselves outgunned financially before they've had a real shot at scaling.

Odyssey Discovery I is the fund attempting to change that math. It's a $50 million seed and pre-seed vehicle focused squarely on UK founders working across applied AI and automation, energy and sustainable industry, and human and planetary health. The fund is currently 50% closed, with Thema among the backers alongside other institutional investors, and a final close is expected after summer.

What makes Odyssey's pitch distinct is less about the cash itself and more about the scaffolding around it — seed capital paired with access to the US market and hands-on operational help, delivered through what the firm frames as strong San Francisco connections. Mark Barry of the British Business Bank described it as converting UK innovation into globally competitive businesses, while Odyssey's Ali Mitchell called this a once-in-a-generation moment for UK founders to build category-defining companies rather than losing ground before they've had the chance to compete.
