Platform
A reliability layer between your financial data and the AI.
Most tools bolt a chatbot onto a spreadsheet. Rexfin builds the missing layer in the middle: a structured model that makes AI answers grounded, consistent, and traceable.
The stack
Four layers, one trustworthy answer.
Data flows up the stack; trust is built at each step. The AI only ever speaks for the model beneath it.
- 01
Connected sources
Accounting systems, banking feeds, warehouses, and uploaded statements flow in continuously. Rexfin normalizes accounts, periods, and dimensions across every source.
- 02
The reliability layer
A structured financial model where every metric is defined once and reconciles to the ledger. Revenue means the same thing on Tuesday as it did on Monday — for everyone.
- 03
Deterministic engine
Calculations run in an exact compute engine, not the language model. Totals, ratios, and rollups are reproducible and tie back to source transactions.
- 04
Grounded AI interface
The AI plans which figures to retrieve and what to compute, then answers from the model — with the assumptions and lineage attached.
Capabilities
Everything in service of one thing: the number is right.
- Reconciliation
- Every derived figure traces back to source entries and ties out to your statements.
- Definitions library
- Metrics, segments, and adjustments are defined once and reused everywhere.
- Scenario engine
- Change an assumption in language; dependent lines recompute across the model.
- Lineage & audit
- Open any number to see how it was built — defensible in diligence and audit.
- Versioned models
- Snapshots per close so historical answers stay stable over time.
- Roles & access
- Per-organization isolation with granular access to sensitive figures.
