Definite
Definite is a Y Combinator (S26) startup building the data layer for finance agents. It plugs read-only into a company's ERP, ledger, payroll, and payments systems and compiles everything into one clean, always-current model of the books. Finance teams can then build back-office agents in plain English on top of that model - without engineers or data pipelines. The system reads and reconciles, but never writes back and never moves money.
