London AI Startups
AI startups build products around machine learning, from tools that help people write, search and analyse information to systems designed for specialist jobs in law, finance, health or engineering. The label covers very different businesses, so the one-line description on each listing is the best place to start.
London has a long history in artificial intelligence research, with leading university labs and research teams in the city. That talent pool, together with customers across almost every industry, makes London a natural home for companies building with AI.
This page lists the AI companies on London Startup Map that have a London office, grouped by the funding stage recorded on each listing. Open a company to read what it does, see its office location, its founders, its investors and any events it is linked to, or switch to the map to see where AI teams cluster across the city. A listing is not a judgement of how good a company’s technology is; for current products and open roles, visit the company’s own website.
