Stacks

Stacks is an AI-native financial close and accounting platform for controllers, CFOs, and accounting teams. It automates the monthly close across existing ERPs with agentic tooling for account reconciliations and transaction matching, journal-entry posting and review, close-management checklists and approvals, and AI-powered analysis, variance explanation, and reporting. Stacks connects directly to ERP systems (Microsoft Dynamics 365, NetSuite, SAP S/4HANA, Workday), data warehouses (Snowflake, Databricks, BigQuery, Redshift), file storage, and spreadsheets, and offers an Excel add-in for manual journals. A developer API for custom reconciliation logic is announced as "coming soon." Stacks is a fintech company backed by EQT Ventures, General Catalyst, Lux Capital, Union Square Ventures, and Version One Ventures. Profile enriched by the API Evangelist pipeline from public web surfaces (no public API specification is yet available).

Stacks is profiled on the APIs.io network. Tagged areas include Company, Fintech, Accounting, Financial Close, and Reconciliation.

Stacks’ developer surface includes signup flow, engineering blog, support, and 9 more developer resources.
