Top Security Startups in 2026

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.
