The Top 10 Unicorns in the United Kingdom The United Kingdom has always been a hotbed for tech innovation, birthing over 100 tech unicorns over the years.

Today, the UK is home to 87 active privately held startups, each valued at over US $1 billion allowing each to reach the coveted "unicorn" status. These unicorns operate in a broad range of sectors, from cleantech to crypto, from healthtech to gaming, and proptech to fintech; each are applying disruptive technologies or business models to disrupt existing sectors or creating brand new ones.

Fintech is by far the most common industry amongst the list of UK tech unicorns, with 18 currently operating in the space. These include six of the country's leading challenger banks, including OakNorth Bank, Revolut, Starling Bank, and Monzo. This dominance comes as no surprise, given that fintech consistently ranks as the UK's top-performing high-growth industry, attracting more equity investment than any other startup sector.

As of 2023, Artificial Intelligence (AI) companies have become the biggest recipients of equity investments, knocking fintechs off the coveted top position. Nine of the companies listed in the 2024 unicorn report feature artificial intelligence in their products, but AI is still in its early-adoption stage. The question isn't will we see AI firms take-over the global unicorn list, but when we should expect to see this happen.

Here is a list of the top 10 unicorns in the UK according to Dealroom data analyzed by Lucidity Insights' research team.
