What Stacks does

Stacks is an AI-native SaaS platform that automates the enterprise financial close for CFOs, controllers, and accounting teams at mid-market and growth-stage companies. Founded in April 2024 in Amsterdam by former Uber and Plaid executive Albert Malikov and now headquartered in London, Stacks deploys a suite of AI 'accounting agents' — including a Flux AI Agent for variance analysis, a Journal Entry Assistant, an Excel Assistant, a Transaction Matching Agent, an Intercompany agent, and an AR/Cash Application agent — on top of customers' existing ERPs (primarily NetSuite, with Xero support). The platform is built on Google Cloud infrastructure (GKE Autopilot, Cloud SQL, Cloud Spanner) and runs its agentic workflows on Vertex AI with Google's Gemini models, achieving claimed transaction match rates above 95% at go-live and improving every period.

The product spans Close Management, Reconciliations, Intercompany, AR & Cash Application, Reporting & Analysis, and Compliance & Audit, replacing spreadsheet-based close checklists, manual reconciliations, and point-tool workflows with a continuously updated audit trail under enforced segregation of duties. Stacks sells via a sales-led, enterprise GTM motion with custom quote-based pricing (no public list price, no self-serve tier), no free trial, and hands-on implementations typically completed in 5 weeks; named customers include Future plc, Epidemic Sound, Volt, Bumper, Motorway, Nivoda, Cleo, Juni, and Datavant — over 30 enterprise customers in total. The company is SOC II Type II, ISO 27001:2022, and GDPR compliant with SOX-ready controls and SAML SSO.

Stacks is venture-backed, having raised approximately $35M in total disclosed funding: a roughly $12M seed round in February 2025 (General Catalyst and EQT Ventures) and a $23M Series A in February 2026 led by Lightspeed Venture Partners with participation from General Catalyst, EQT Ventures, and S16VC. The Series A was paired with the launch of the Flux AI Agent and a brand repositioning around 'Agentic Close for Enterprise,' with stated plans to scale enterprise adoption globally beyond the UK/Europe footprint. The company operates from London (HQ) and Amsterdam (engineering/R&D base) with a team in the 11–50 range.

Revenue model

1. SaaS subscription (enterprise contracts): Stacks sells its AI close platform to enterprise customers via custom, quote-based SaaS contracts. Pricing is not publicly disclosed; the company directs all prospects to a "Book a Demo" flow. Customers report that implementation is fast (hours for Volt, 5 weeks for Epidemic Sound and Nivoda), implying an enterprise land-and-expand motion in which modules (Close Management, Reconciliations, Intercompany, AR & Cash, Reporting & Analysis, Flux AI Agent) are added over time.
2. Usage / value-based pricing signals: The Google case study and product pages position the product around measurable outcomes (hours saved, close-cycle reduction, reconciliation match rate) which is consistent with enterprise subscription tiers scaled to transaction volume, entity count, or number of bank accounts (e.g., Nivoda's 130+ bank accounts across 13 entities, Epidemic Sound's 100+ bank accounts across 13 legal entities). Public price points are not disclosed.

Core offering

Stacks sells an AI-native, agentic close platform for enterprise finance teams. Its AI accounting agents sit on top of customers' existing ERPs to automate the full financial close cycle — journal entry preparation, bank and sub-ledger reconciliations, intercompany matching, accounts receivable / cash application, and variance (flux) analysis — replacing spreadsheet-based, manual close workflows with a continuous, audit-ready workflow.
