The Top 50 AI Companies in the UK | 2021 Ranking

| John Davis

Artificial intelligence (AI) is consistently a top-performing sector, with  1,412 high-growth AI companies currently operating in the United Kingdom. These startups and scaleups have collectively raised £19.6b of equity investment across 6,123 funding rounds, employ an estimated 23.8k people and generate £1.62b in reported turnover. 61% of UK AI businesses are based in London

Artificial Intelligence is about applying deep learning and machine learning—specifically through algorithms—to build machinery and software capable of completing complex tasks. For instance, tasks that require emotion, ‘human-like’ contextual problem-solving, or the use of real-time neural network analysis.

And it doesn’t exist in a vacuum. Instead, AI solutions span almost every discipline and sector that we track— from fintech companies, to mobile apps and chatbots, healthcare and self-driving cars. The leading sector crossover for artificial intelligence companies is with Software-as-a-Service (SaaS).

We’ve profiled the top 50 AI companies driving growth in the UK, which have each attracted at least £20m in investment—providing jobs, generating turnover, and creating innovative technology along the way.

Roborace organises motor racing championship for self-driving cars, all of which are electric and utilise artificial intelligence software. In December 2020 the company held its Season One Beta at Thruxton in the UK, live-streamed through popular platforms such as Twitch. Teams that raced in the tournament included Arrival Racing—powered by UK unicorn Arrival—MIT Driverless, and Carnegie-Mellon University. The hardware for each car is standardised, meaning that the only differentiator is the AI technology developed by each team.

The cars operate physically on the racing track, but also within a mixed ‘computer reality’, where obstacles and rewards are overlaid on the track virtually. The algorithms driving the cars must react to virtual obstacles and go out of their way to collect items—such as coins—which will either add penalties or reduce their overall racing time. This ensures variety in the races, as the AI algorithms developed by each team calculate the ‘cost’ of routes in real-time, working out the path of least resistance. 

Roborace is operating in stealth mode, raising all of its £72.7m funding from unannounced sources.
