About the company

Stacks offers an AI-powered platform that helps enterprise finance teams automate and streamline the monthly financial close. It uses AI agents to perform tasks like reconciliations, journal entries, variance analysis, and reporting, all built on a data layer that connects to ERP systems (such as NetSuite) for a unified view of financial data. A standout feature, AI Flux Analysis, identifies drivers of variances, provides context, and drafts explanations, while close management keeps tasks on track for an audit-ready environment. The platform differentiates itself with rapid deployment from its data-layer integration and an agent-driven workflow that learns from user feedback, aiming to shorten close times, reduce manual work, lower risk, and support mid-to-large enterprises with customers like Volt and Epidemic Sound.

Stacks Raises $23 Million to Reinvent Finance Operations With Agentic AI - stacks.ai

Stacks raises $23M Series A led by Lightspeed to power agentic AI for enterprise finance.

Stacks Raises $23 Million to Reinvent Finance Operations With Agentic AI

Stacks raises $23 million to reinvent finance operations with agentic AI. Stacks, helping reinvent the financial close, led by Albert Malikov and the team, has raised $23M Series A led by Lightspeed, with EQT Ventures, General Catalyst, and S16VC doubling down. The round comes less than a year after Stacks' $12 million seed financing led by General Catalyst, underscoring the company's rapid traction and momentum. Finance is becoming the next major enterprise function to be rebuilt with AI, following multibillion-dollar transformations in customer support and legal. Since emerging from stealth less than a year ago, Stacks has onboarded more than 30 enterprise customers globally, saving finance teams over 100,000 hours annually by automating reconciliations, journal entries, and the month-end close. Fragmented data across ERPs, spreadsheets, data lakes, and legacy systems forces finance teams into manual reconciliation and limits real-time visibility. Stacks addresses this by building a financial data layer that connects directly to finance systems and creates a unified view, supported by deterministic machine-learning tooling for reliable enterprise-scale automation. On this foundation, the platform deploys agents that automate operational workflows, improving speed, accuracy, and leverage. According to Alex Schmitt of Lightspeed Venture Partners, the team's technical and finance background and strong traction position the company to lead AI adoption within the Office of the CFO. Stacks is delivering measurable ROI through its monthly close module and expanding into daily operational workflows. At Nivoda, the accounting team reduced monthly close time by eight days, cut journal postings from days to minutes, and automated 95% of reconciliations, according to JP. At Epidemic Sound, Jessica Lindholm reported replacing a legacy provider within weeks and benefiting from AI-driven automation across financial close and reconciliations, with further evaluation of AI agent capabilities underway. With its data foundation established, Stacks is expanding from close automation into financial intelligence. The company introduced a reporting and analysis suite designed to move teams beyond manual reporting toward automated business explanation. Its AI Flux Analysis automates variance analysis, identifies transaction-level drivers, incorporates historical context, and generates reviewable explanations, while a leadership-ready executive summary marks the first layer of a broader enterprise finance intelligence suite. Targeting both the $100 billion Office of the CFO software market and the broader labor spend behind enterprise finance, Stacks is building an AI-native platform end-to-end. The close and reconciliation segment remains dominated by incumbents such as BlackLine, HighRadius, and OneStream, whose legacy systems are often complex and costly to deploy. According to Albert Malikov, the platform began with accounting and close workflows and addressed fragmented data first by creating an AI-ready data layer, enabling AI agents to operate in finance and shifting CFO teams toward analysis and decision-making.

Lightspeed leads $23M investment in AI startup for accounting departments Stacks

Lightspeed leads $23M investment in AI startup for accounting departments Stacks. The Series A in Stacks also includes returning investors EQT Ventures, General Catalyst, and S16VC. A London-headquartered AI startup targeting accountancy departments, set up by a former Uber and Plaid executive, has raised $23 million in a Series A round, led by new investor Lightspeed. The Series A in Stacks also includes returning investors EQT Ventures, General Catalyst, and S16VC. The new round follows 12 months after its $12m seed round. It has raised $35m in total. Stacks, founded in Amsterdam but headquartered in London, is an AI platform for enterprise accounting teams. Its tech is remedying the challenge of scattered data in enterprise finance. It says that transaction-level detail is scattered across ERPs, spreadsheets, data lakes, and legacy systems, forcing teams into manual workarounds because core platforms are slow, difficult to integrate, and not built for AI. Stacks says it has built a data layer that connects directly to finance systems and creates a single, consistent financial view across them. It says it has also built machine-learning tooling required to make automation reliable at enterprise scale and is deploying agents that automate workflows across the finance stack. Its 30 clients include the publisher Future and audio firm Epidemic Sound. Stacks was set up by CEO Albert Malikov, who, before founding Stacks, held product leadership roles at Uber and Plaid, where he worked on scaling Plaid's European business. Alex Schmitt, partner at Lightspeed, said: "Stacks is uniquely positioned to tackle some of the toughest challenges in enterprise finance. The team's mix of technical and finance expertise from Uber and Plaid, along with the company's remarkable traction, gives us strong conviction that they will lead the AI shift inside the Office of the CFO."

Enterprise finance platform Stacks raises €19 million to streamline reporting and month-end workflows

Enterprise finance platform Stacks raises €19 million to streamline reporting and month-end workflows. February 19, 2026 Stacks, a British agentic platform for enterprise finance, has raised a €19 million ($23 million) Series A - introducing their new reporting and analysis suite, at the core of which sits their new offering; AI Flux Analysis. The round was led by Lightspeed, with EQT Ventures, General Catalyst, and S16VC doubling down. The round comes less than a year after Stacks' €10 million ($12 million) seed financing, as covered by EU-Startups. "We started with the most manual and foundational workflows in finance: accounting and the close," says Albert Malikov, Founder and CEO of Stacks. "From day one, we focused on solving the core problem: fragmented data. By building an AI-ready data layer, we're unlocking what's needed to bring AI agents into operational finance, shifting CFO teams from process execution to higher-value analysis and decision-making." Recent EU-Startups reporting shows continued investor appetite for enterprise AI and adjacent data infrastructure across 2025 and early 2026. Stockholm-based Agaton secured €8.4 million in Seed funding to scale its agentic AI platform focused on converting customer conversations into revenue insights, while Germany's Blockbrain raised €17.5 million in a Series A round to advance enterprise-grade AI agents that capture and operationalise organisational knowledge. In the UK, London-based SurrealDB announced a €19 million Series A extension to scale its multi-model database infrastructure for AI applications, marking additional British activity in AI-focused enterprise software. Together, these adjacent rounds amount to approximately €44.9 million in disclosed funding, rising to roughly €63.9 million when including Stacks' €19 million Series A. Collectively, the funding reflects sustained capital flowing into platforms that address fragmented data, enterprise automation and AI deployment within core business functions, situating Stacks' raise within a broader 2025-2026 enterprise AI investment cycle. "Stacks is uniquely positioned to tackle some of the toughest challenges in enterprise finance," adds Alex Schmitt, Partner at Lightspeed. "The team's mix of technical and finance expertise from Uber and Plaid, along with the company's remarkable traction, gives us strong conviction that they will lead the AI shift inside the Office of the CFO." Founded in 2024 by former leaders from Uber and Plaid, Stacks is an AI platform for enterprise accounting teams. The company uses AI agents to automate operational finance workflows, including reconciliations, journal entries, flux analysis, and the month-end close. Stacks is used by more than 30 enterprise customers globally, including Volt, Motorway, Cleo and Bloom & Wild, and reportedly reduces close cycles by as much as 50% and saves finance teams over 100,000 hours annually by automating reconciliations, journal entries, and the month-end close. "The time savings are material. We were surprised just how quickly the value showed up," says Jack Nottage, Head of Finance at Motorway, the online used car marketplace, whose finance team reconciles several thousands of payments weekly and was able to cut time spent handling reconciliation by 40 hours per month within weeks of integrating with Stacks. The company believes that fragmented data remains one of the biggest structural barriers in enterprise finance. Transaction-level detail is scattered across ERPs, spreadsheets, data lakes, and legacy systems, forcing teams into manual workarounds because core platforms are slow, difficult to integrate, and not built for AI. As a result, finance teams spend more time reconciling numbers than operating with real-time visibility. Stacks built its platform by solving this foundation first. The company developed a data layer that connects directly to finance systems and creates a single, consistent financial view across them. It has also built deterministic machine-learning tooling required to make automation reliable at enterprise scale. On top of that foundation, Stacks has deployed agents that automate operational workflows across the finance stack. "With Stacks, we're saving a noticeable amount of time on the finance close, and as a result we can produce the management accounts faster each month," said Andy Murray, Head of Finance at Cleo, the AI-native personal finance assistant, who onboarded with Stacks to improve the team's critical workflows. Cleo now reports 80% faster journal entry processing and the ability to pull data between systems to produce enhanced financial reports within seconds. The company today introduced a new reporting and analysis suite aimed at moving finance teams beyond manual reporting and toward automated business explanation. At the centre of the launch is AI Flux Analysis, a product that automates variance analysis and replaces spreadsheet-based commentary with explainable, account-level investigation. Flux identifies variance drivers across transactions, pulls historical context across periods, and generates explanations that finance teams can review and refine. Stack is also introducing a leadership-ready executive summary, which represents the first layer of a broader intelligence suite for enterprise finance. "We slashed our monthly close time by eight days," said JP, Global Head of Accounting at global jewelry trading platform, Nivoda. "Journal postings went from days to minutes, and we automated 95% of reconciliations."
