Top Artificial Intelligence Startups in United Kingdom

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.

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. Founding Team: - Max Ahrens (Founder & CEO):** ML PhD + Postdoc (Oxford University); led AI research projects with the Alan Turing Institute and UK Ministry of Defence; ex-McKinsey. - Simon White (Founding Software Engineer):** former YC startup founder/CTO; ex-defence systems engineer. - Joel Kang (Founding Product Engineer):** former AI startup founder/CTO; ex-LinkedIn; product-minded engineer focused on shipping end-to-end systems.

We’re an end-to-end solution for launching, upskilling, or switching into a career in AI & data. We deliver an immersive programme that launches careers in Ai & Data at supersonic speed. Over 18 weeks, users log into the AiCore Portal, which gives them access to a sandbox cloud environment where they find everything that they would encounter in industry (data, running code, and other stuff) and are challenged to build and deploy production-grade systems, learning under the mentorship of industry experts. These systems are created using blueprints from leading companies such as Facebook, Airbnb, Pinterest and more, developed in collaboration with the engineers who built them. 'It's like a flight simulator for working environments' 97 million roles in AI & data will be created by 2025. There is no single path to one of those 97 million roles. But, there is a proven path - the AiCore programme. Hundreds of learners commit to the programme to launch their careers every year. You will play a vital role in scaling this to 3000 this year. We’ve been growing at +92% each quarter for over a year now. To keep up this pace, we need more ambitious individuals to join our high performing team and take on vital responsibilities.

Established in 2018, we are a London-based company started by deep learning veterans with huge ambitions. V7's goal is to develop a single platform to develop the sense of sight for any visual task, from microscopy identification, to manufacturing, or robotic picking. We believe neural networks and learnt approaches will replace hand-coded software as we know it. Our goal is to power the intelligence of 1 billion devices by 2030.
