The story

Stacks was founded by a team with backgrounds at Uber (Payments), Plaid, Mollie, Bunq, and Miro to build an agentic AI platform that sits on top of enterprise ERPs and automates the month-end close. It emerged from stealth in 2025 and is positioning itself against BlackLine, FloQast, and Numeric — using AI agents to reconcile transactions, post journals, prepare working papers, and draft audit-ready commentary. The company is UK/EU-headquartered (London operations, Dutch legal entity) and targets multi-entity, multi-currency enterprises.
