Track 00 — SaaS / Subscription

The Hub Suite — three operational systems of record.

Three independent multi-tenant SaaS platforms, each a defensible system of record for a regulated industry. Use one, two, or all three — they don't depend on each other. Same RLS-first architecture, same audit-by-default principles, different regulatory regimes.

Compliance Hub — UK facilities compliance (LOLER, PUWER, RIDDOR, RAMS, Fire, L8, CDM…). FM Control Hub — multi-territory estate ops with Contractor Portal. Care Hub — CQC-regulated care homes with eMAR, NEWS2, HACCP, L8, COSHH. Every tier is hosted, supported, and live today.
