Agentic AI for Financial Close & Accounting Automation
Stacks is an enterprise agentic AI platform that automates the financial close process for finance and accounting teams, handling reconciliations, journal entries, intercompany eliminations, AR/cash application, and variance reporting. It connects directly to ERPs like NetSuite, SAP, and Microsoft Dynamics and posts audit-ready work with a full audit trail, rather than only tracking tasks like traditional close-management software. It serves finance teams at growth-stage and enterprise companies.

At its Series A announcement it had onboarded 30+ enterprise customers (including Cleo, Epidemic Sound, Motorway, and Bumper) and reported saving finance teams over 100,000 hours annually.
