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.

Same IR always produces same outputs. Audit-defensible against any skeptical board.

A sensitivity sweep across 50 drivers counts as ONE billable compile. Templated multi-client work compounds cleanly inside the metered tier.
metered pricing →<50/ month
Average client model fits in the free tier. Metered overage only on the heavy ones.

One typed model, four cuts, one afternoon — whether that's four clients, four business units, or four scenarios. The two in signal-orange flagged assertions you'd otherwise hunt by hand. Each cut still gets its own 100/100 Excel and its own audit trail. The leverage is throughput; the moat is that nothing ships unaudited.
