16 UK soonicorns to watch

The UK has led the way when it comes to producing Europe's unicorns — so which startups could be next to pass the threshold?

2024 is likely to be another tough year for UK tech. 

Britain’s technology secretary Michelle Donelan told Sifted last month that the UK should aim to match US levels of VC investment as a share of GDP by 2030, which would involve pumping £5bn per year more into British startups. 

It comes amid huge incentives for British startups — and European startups more generally — to relocate to the US, where subsidies via the US Chips Act and Inflation Reduction Act, as well as the general availability of VC funding, are a lucrative carrot. 

The UK remains a strong hub for entrepreneurship, particularly in areas like fintech. But the number of new VC funds raised fell from 67 in 2022 to 46 in 2023. In France, VCs closed 29 new funds up from 26 a year earlier. 


And what about unicorns? Well, the UK minted two $1bn+ startups in 2023 — Synthesia and Quantexa, both AI companies, a far cry from the 12 in 2022 and 16 in 2021. Could 2024 be better? Below, Sifted takes a look at 16 British startups that are on track for unicorn status.
