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.

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.
