A seed-stage, venture-backed startup building an AI operating system for the finance and CFO function — deploying audit-ready AI agents that connect to a company's existing finance stack (ERPs, banks, billing, payroll, CRM, contracts, email) to automate the work behind close, revenue recognition, reporting, cash management, and audit readiness.

• Architect the financial data platform: ingestion, normalization, reconciliation, and the canonical ledger model that turns data from ERPs, banks, billing, payroll, CRMs, and email into a trustworthy source of truth.
• Design the durable execution layer for long-running AI workflows and the exactly-once, audit-ready write-back path to ERPs and systems of r...
