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.

  1. 01

    Connected sources

    Accounting systems, banking feeds, warehouses, and uploaded statements flow in continuously. Rexfin normalizes accounts, periods, and dimensions across every source.

  2. 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.

  3. 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.

  4. 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.
