Last year, the UK produced 11 unicorns — more than any other country in Europe and accounting for 23% of the 47 total unicorns "born" on the continent in 2022. That was nothing compared to the heady days of 2021 though, when the country produced 38 billion-dollar businesses, 55% of Europe’s herd that year.

Where once becoming a unicorn was many a startup’s dream, recently the magic has faded for some: plenty of billion-dollar businesses have lost the title — UK climate tech Britishvolt collapsed into administration this year and now publicly listed used car platform Cazoo and digital doctor Babylon are valued at far less than $1bn. 

Despite the doubts, reaching the horned status is still quite a feat and retains some of its sparkle for much of Europe’s startup scene. So, who could be next to make it past the mark? Here are 12 UK-based startups that are well on their way to that $1bn+ valuation, according to Dealroom data.
