Light vs cfo.ai
cfo.ai, formerly Runway, is an AI financial planning platform: Ari, its AI CFO, reads your ledger, banking and payroll, builds the model and the scenarios, plans headcount and drafts the board pack, refreshing actuals overnight. It is not a general ledger: it never writes back to your books and does not close them. Light is the agentic ERP where budget, forecast and variance run on the posted ledger itself, so the plan is measured against the books rather than against a copy of them.
