Productivity without vendor lock-in

• Data sovereignty concerns — Your corporate data lives on someone else's servers, in jurisdictions you don't control
• Per-user costs add up — $12-20/user/month becomes significant at scale
• Vendor lock-in — Migrating away from Google or Microsoft is painful and expensive
• Compliance complexity — Meeting data residency and industry regulations with SaaS is challenging

A self-hosted productivity suite that you own, deployed and managed by us.
