Top Tech Startups in London, United Kingdom in 2026

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waste hundreds of hours each month on fragmented tools, spreadsheets, and DMs,struggling with messy creator outreach, outdated briefs, slow sample fulfilment, and scattered performance data.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.

Billions of people want to move countries, but when they do they are locked out or overcharged for the financial products most people take for granted. Since 2017 we've set out to change that. We've since insured over 1 million people, and are one of the fastest-growing companies in Europe doing over half a billion of annual revenue. And, we've only just got started - we have so many more products to build & customers to service. We believe to be continually successful we need to attract the best people. So far we have 600+ people across 3 countries, and we are always on the look-out for more brilliant people. People who are ambitious, smart, collaborative, and attracted to getting things done.

Ivo was founded by a contract attorney and built by a team of lawyers, technologists, and operators with deep experience in contract work. We've experienced firsthand how manual, fragmented contract workflows slow down business, introduce risk, and drain legal teams. That perspective informed our flagship product: an AI-powered redlining tool that helps teams move faster—without compromising legal judgment. Since then, Ivo has grown into a broader platform, serving not just in-house legal teams, but also procurement, sales, and other key business functions. In addition to AI redlining, our suite includes a smart repository for organizing and managing contracts, and a powerful agentic assistant that helps teams get answers fast—always backed by source-grounded context. Originally founded in New Zealand and now headquartered in San Francisco, Ivo is backed by top-tier investors and trusted by global enterprises and fast-growing startups. We’re proud to support some of the most innovative teams in the world at companies like Pinterest, Quora, and Canva—and we’d love to support yours, too.

Trellis is an early-stage EdTech startup on a mission to streamline admin and support learning. Our AI-powered platform tackles one of the biggest drivers of teacher burnout: support planning meetings and related paperwork for learners with Additional Support Needs (SEND in England). We are backed by the Scottish Government’s innovation programme, CivTech, and Learning Directorate. Our approach is rooted in Human-in-Command. We use secure AI as a background assistant to transcribe meetings, draft Child’s Plans compliant with government frameworks, and generate meeting minutes. We have already returned several hundred hours to staff so they can focus on what matters most: spending time with children and families. Having just wrapped up a successful pilot across 7 Scottish local authorities – scaling to 78 schools, saving teachers an average of 57 minutes per meeting write-up, and cutting document distribution times from 12 days to 5 – we are now preparing for national scale-up.
