Top B2B Startups in London, United Kingdom

Polaron is a startup specializing in AI-driven materials design. The company focuses on accelerating the development of advanced materials for applications such as batteries, wind turbines, and other climate-critical technologies. Its machine learning algorithms leverage image data to characterize and optimize materials faster and more accurately than ever before. Polaron's platform employs generative AI algorithms trained on microstructural image data to model the intricate relationships between manufacturing processes, material structures, and performance outcomes.

Scoutly is a casting operating system for agencies. We replace the mess of WhatsApp, emails, PDF decks and spreadsheets with one connected workflow: briefs, shortlists, holds, client approvals, bookings and invoice tracking. The goal is to give agencies a client-ready control room so decisions stay organized and nothing slips through the cracks.

We focus on solving the hardest, most overlooked problems for the enterprises that depend on them. Supply chains have always been volatile, but the last few years have shattered any illusion of stability. Three ‘once-in-a-lifetime’ supply chain shocks—COVID-19, war in Europe, and tariffs—have tested even the most resilient operations. Most enterprises have hundreds of employees dealing with suppliers at different operational levels. Making analysts sift through siloed data and thousands of contracts is neither feasible nor economically viable. Companies must act fast to seize value to stay competitive. Humans alone simply can’t keep pace. Our first wave of Mages focuses on just this. Mages join teams as employees, executing work end-to-end to deliver savings on the back of the data transformation work that companies have worked hard on.

The security industry has spent years making detection faster. Better scanners. Smarter alerts. More automation. Now AI can find and fix vulnerabilities in minutes. Yet the same classes of weakness continue to appear in audits, pentests, and incidents. The problem is not speed. The problem is that nobody is looking at the architecture. Software systems are not understood, they are assumed. Engineers inherit codebases. Services accumulate. Trust boundaries emerge across teams, clouds, and CI/CD pipelines. Over time, nobody has a complete picture of how the system actually works. Veriom changes that. We build a unified structural model across code, cloud, CI/CD, and production environments, helping organisations understand how their systems are actually structured and where architectural weaknesses create risk before they become vulnerabilities. We are venture-backed, have paying customers, and were selected by the UK Government to represent British cybersecurity innovation at RSA Conference 2026 in San Francisco. We are a small team with a systems engineering mindset, a love for hard technical problems, and a genuine belief that software systems should be understandable. If that sounds like a problem worth solving, we'd love to meet you.
