Brain health today is invisible and inaccessible. Over 300 million people live with untreated or misdiagnosed cognitive conditions, facing long waiting lists, fragmented specialists, and high out-of-pocket costs. Unlike physical health, there is no routine panel for the brain. Connectome solves this by making brain insights as accessible as a blood test — turning the brain into a routine, trackable part of whole-body health, and building the world’s largest longitudinal brain dataset in the process. At its core Connectome is a fast, non-invasive brain scan that produces a standardized panel of metrics. These power our predictive ML engine, and lifestyle alignment score that integrates wearables and behaviour data. Together, they make brain health measurable, optimisable, and scalable through clinics, wellness centers, and digital health partners.

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.

We advise regulated firms on the obligations attaching to the artificial intelligence systems they build, buy and deploy. We identify which of those systems will fail regulatory scrutiny, and what must change before they are examined. Our work spans the EU Artificial Intelligence Act, UK GDPR, FCA Consumer Duty, the Senior Managers and Certification Regime, PRA model risk expectations, the Money Laundering Regulations, and the Equality Act. Most firms are subject to several of these at once. Few have assessed their systems against all of them. Engagements are fixed in scope and fixed in fee. Findings are cited to the article, and to the enforcement record that shows how regulators have actually applied it. Others advise on artificial intelligence among many things. We advise on nothing else. Strathwill Ltd, London. Company No. 17133379. Regulatory compliance advice. Not legal advice.

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.
