ARR, renewals, usage, debtors: every figure on every page and in every chat answer is computed once, from one set of facts, so the site, the chat and your reports agree.
The facts are built inside your own Snowflake from your systems' exports, so your data stays where it is and B-Brain works on top of the warehouse you already run.
Where the systems themselves disagree, such as invoiced ARR against the CRM, B-Brain shows the reconciliation rather than quietly picking a winner.
