Top Artificial Intelligence Startups in United Kingdom

Early-stage startup.

Mickai builds MICKAI, a Sovereign Intelligence Operating System (SIOS): AI that regulated organisations own and run inside their own walls, offline, on hardware they control. Where mainstream AI rents you someone else's model, on someone else's cloud, under someone else's rules, we move all three inside your perimeter. We have built it. Instead of one monolithic model, a cooperative substrate of specialist brains that reach consensus before any sensitive action. Every action is written to a tamper-evident, cryptographically signed, post-quantum Open Audit Record you can verify offline for years. Sensitive actions are voice-biometric gated and reversible, keyed to hardware the operator holds. On top of it we have built the everyday tools a business runs on, email, CRM, help desk, collaboration, finance and more, as 87 studios of private, on-device AI. We launch with ten; the rest follow in sequence. The architecture is protected by 104 filed UK patent applications across 2,340 claims, owned outright. We serve defence, finance, government, healthcare and other regulated sectors that cannot send their data to the public cloud. We are a small, fast, deeply technical team, hiring the people who will help us define the category.

Splitsense is building an AI agent that does conversion optimization the way a senior CRO specialist would, end to end and continuously. The problem we're solving is one every founder and growth team knows. You have analytics, heatmaps, session recordings and dashboards, but none of them tell you what to actually do. Turning that data into insight takes hours of digging. Turning insight into an experiment takes developer time most teams don't have. So most websites never get optimized at all, and the ones that do run a handful of tests a year instead of a steady stream. That's a hard problem because good CRO isn't one skill, it's a pipeline of them: reading funnels and spotting where users drop off, forming hypotheses worth testing, writing copy that converts, building variants without breaking the site, running the statistics honestly, and knowing what to test next. We're encoding that entire pipeline into autonomous agents. Splitsense crawls your site, learns your brand and audience, analyzes real visitor behavior through its own analytics and session replay, finds the leaks, then writes, launches and measures A/B tests on its own. Multi-armed bandits shift traffic to winners while tests run, so learning turns into revenue faster. The result: the kind of continuous experimentation program that used to require a CRO consultant, a copywriter, an analyst and an engineer, now available to a solo founder for the price of a SaaS subscription. We're a small, senior, fully remote team that ships fast and uses our own product on our own funnel every day. If you want your work to compound, everything we learn makes the agent smarter for every customer.

We’re building Lumo, the first AI-native operating system for TikTok Shop. Our mission is simple: replace the manual chaos of affiliate marketing with a fully autonomous growth engine. Today, brands and agencies waste hundreds of hours each month on fragmented tools, spreadsheets, and DMs,struggling with messy creator outreach, outdated briefs, slow sample fulfilment, and scattered performance data. Even when campaigns work, momentum stalls because there’s no system to recycle what’s winning. Lumo solves this by acting as a performance brain for social commerce. Our OS automates every step of the affiliate lifecycle: Creator Radar finds and qualifies high-GMV creators from a 3M+ profile database, enriched with live TikTok data. AI Outreach Hub sends personalised DMs and emails at scale, automating follow-ups and boosting creator response rates. Smart Brief Generator turns SKU inputs into trend-informed, compliance-checked content briefs aligned to TikTok’s fast-moving formats. Pearformance Tracker centralises GMV, CTR, ROAS, and other data,scoring campaign health in real time. Creator Flywheel recycles top campaigns, creators, and briefs into ongoing growth loops instead of one-off wins. AI Autopilot continuously optimises budgets, commissions etc, making real-time decisions like a strategist would,only faster. We’re building this because TikTok Shop is exploding ($20B+ GMV in 2024, doubling again by 2026), yet native tools are lagging. Competitors like Reacher and Euka prove demand (Reacher hit $2M ARR in year one), but they’re focused on point solutions. Lumo is different: it’s the full-stack OS, fusing automation with intelligence. Our edge comes from being both a TikTok Shop Partner agency (running £500K+ monthly GMV for brands) and a product company. That means our models are trained on ground-truth campaign data, giving us operational resilience and predictive accuracy no outside tool can match.
