Stacks

Stacks is an agentic AI platform for enterprise finance teams. Its software connects to a customer's ERP and other finance systems and deploys AI agents across the record-to-report cycle: matching transactions across subledgers, bank feeds and the general ledger; preparing and posting journals, accruals and working papers against company policies; matching, netting and eliminating intercompany balances across entities; applying payments to open invoices and extracting remittance data; and drafting variance commentary for sign-off and board reporting. Compliance features include segregation-of-duties enforcement, anomaly detection ahead of audit findings, and a logged audit trail covering entries, exceptions and overrides.

The company positions the product for mid-size to large, multi-entity enterprises, including public companies, and states that customers can be operational in under two weeks without data migration projects because the platform integrates with existing ERP systems and tools such as Excel and Slack. Stacks reports platform-level outcomes of roughly 40% faster close cycles, 76% of reconciliations auto-matched and 15% quicker audit cycles.

In February 2026 Stacks extended the platform beyond close automation into reporting and analysis, launching AI Flux Analysis, which automates variance analysis by identifying variance drivers across transactions, pulling historical context across periods and generating account-level explanations, together with a leadership-oriented executive summary described as the first layer of a broader intelligence suite.

Founding story

Founder and CEO Albert Malikov previously served as Head of International Product at U.S. fintech Plaid and before that held a senior product role on Uber's Money team, where he observed inefficiencies in monthly finance processes. He assembled a product-centric founding team drawn from Uber, Plaid, Miro and Mollie and built the initial close product over roughly nine months before the company's February 2025 funding announcement.

Business model

Stacks sells software to enterprise finance and accounting departments, deployed by connecting to the customer's existing ERP and data sources rather than through data migration. The company describes an AI-powered workspace in which finance teams and AI agents collaborate on close workflows, with agents handling automation and staff reviewing exceptions and providing sign-off.

Traction

Within nine months of building the product, Stacks had onboarded dozens of companies and begun generating revenue, with early customers reporting a 47% reduction in close time, a 97% decrease in manual reconciliations and a 33% faster audit cycle. By February 2026 the company reported more than 30 enterprise customers globally and stated it had saved finance teams over 100,000 hours annually. Nivoda's global head of accounting reported cutting monthly close time by eight days and automating 95% of reconciliations, and Juni's CFO reported a three-and-a-half-day reduction in close time.

Latest developments

In February 2026 Stacks raised a $23m Series A led by Lightspeed, with EQT Ventures, General Catalyst and S16VC participating, and simultaneously introduced a reporting and analysis suite centred on AI Flux Analysis for automated variance analysis and account-level explanations, plus an executive summary product. Lightspeed partner Alex Schmitt joined as the firm's deal lead.
