Top Artificial Intelligence Startups in London, United Kingdom

At Maihem, our mission is to empower every manufacturer, no matter their scale, to invent and build anything using intelligent robots. We are witnessing the start of a new industrial revolution—an era of rapid innovation and advanced manufacturing powered by AI and robotics. We aim to lead this shift by putting these tools into the hands of every manufacturer, ensuring the power to invent and build at scale isn’t a privilege of the few. But this era of abundance depends on solving a systemic labor crisis. For any economy to advance its industry and secure its supply chains, it must address the work that no longer attracts a human workforce. We are building AI to handle the dull, dirty, and dangerous. By offloading the hazardous and the mundane to intelligent machines, we empower manufacturers to compete globally while driving prosperity locally. In doing so, we enable the creation of new, purposeful jobs—ensuring that the future of innovation remains human-centric, boundless, and accessible to all. We are: - Backed by Y Combinator and founders of PayPal, Affirm, Slack – with a $6M seed round. Scout investments by Sequoia, a16z, Accel, and Kleiner Perkins. - Founding team of AI PhDs and previous startup CTOs** – everyone has a founder/CTO background. - Building with real industry partners from the start** – focused on shipping robotic solutions for real-world deployment in record time.

Quality AI will help healthcare providers save more lives through better, faster screening and detection. Aival bridges the gap between clinicians and AI vendors, allowing an AI system to be properly analysed and monitored, and to give healthcare professionals the confidence needed to know it will work at a local site and for their patients. Using Aival's software, clinicians and decision makers can evaluate different AI products quickly, and choose the ones which offer greatest clinical benefit for their patients. We were formed in 2020 and are funded by Antler, The British Robotics Seed Fund and Innovate UK.

We're here to change the way people use insurance - safely, compliantly, and on their terms. AI is increasingly where people turn to handle things like insurance. They’re complex products, with real life relevancy, and they’re often not explained well by their providers. That’s great in principle, but it creates real problems for insurers, customers, and regulators - a lot of the machinery that exists around agents today is simply not built for regulated products. Marrow is building the platform that fixes that: the compliance-grade infrastructure that every AI insurance agent runs on. We're live with Aviva, one of the UK's largest carriers, and building a pipeline across the UK and Europe. We’re on the path to regulated status in our own right, are VC-backed, and have a small team that's moved faster than most companies ten times our size. Off the back of a recent fundraise, we’re hiring a small number of high-leverage roles to help us move forward in leaps and bounds.

Vestico combines AI & user-generated content to show shoppers how clothes fit before they buy & collect actionable data throughout their shopping journey. Most of us don't look like the models we see online, so it's difficult to make the right decisions about size and fit. Returns in fashion e-commerce can go as high as 60% and cost retailers over $500B every year in the US alone. Far more importantly, e-commerce returns are having a devastating impact on our planet due to emissions, repackaging, restocking, and waste, with over six billion pounds of returned clothes ending up in landfill in 2019. Vestico solves the returns problem for retailers by showing shoppers how products look on people just like them. We give shoppers the confidence to buy and the information to buy intelligently, reducing returns and boosting conversion. By combining the authenticity of user-generated content with sizing AI, Vestico supports diverse representation at scale while solving the online fashion shopper's biggest pain point.
