As answered by people managing CrewTrackr and LayerStack Arm-based Cloud Server.
CrewTrackr's answer
General contractors (the "owner"/office-staff role) who manage multiple subcontractors across active job sites, and their subcontractors (the "sub" role, who get a stripped-down view limited to their own compliance record). It's built for small-to-mid GC shops still running this on spreadsheets and text messages
CrewTrackr's answer
It bundles three things GCs normally track in separate spreadsheets/email threads into one multi-tenant tool — subcontractor compliance (COI, license, W-9 expiry tracking with alerts), weekly payroll logging by project/sub, and permit tracking by project — plus a self-service portal where subs upload their own documents instead of the office chasing them down.
CrewTrackr's answer
It exists to replace juggling spreadsheets, email threads, and text messages for tracking sub compliance/payroll/permits. It's explicitly architected multi-tenant from day one "even if you only have one org right now," anticipating the first real customer rather than reacting to one.
CrewTrackr's answer
Next.js 15.5 (App Router) + React 19 + TypeScript, Supabase (Postgres, Auth, Storage, Row Level Security) as the backend, Capacitor for the iOS/Android mobile shells
