The model layer
your stack is missing.
You've automated the rest — AP, AR, the close — with Claude Code, MCP, and your ERP's API. The financial model is the last thing still living in a spreadsheet. Flatland is the typed, recomputable, audit-trailed layer that fixes that: assumptions with names and types, a real dependency graph, institutional-grade exports your board, investors, diligence partner, or auditor expect.

Your compile runs on our servers and is saved so you can share it. It also feeds the live heartbeat: counts, timing, and a coarse region — never the model itself.
