Amsterdam-based Stacks, which builds AI software to automate accounting workflows, raised a $23M Series A led by Lightspeed, after a €10M seed in 2025
Stacks, which builds AI software to automate accounting workflows, raised $23 million in Series A funding, CEO Albert Malikov tells Axios exclusively.
Context & Ripple Effects
Stacks’ Series A follows its €10M seed in 2025, giving the company a larger financing base to pursue AI-driven accounting workflow automation.
The raise sits within a growing cluster of finance-operations automation startups: Copenhagen’s Light previously raised a $30M Series A for AI accounting and bookkeeping software, while Stuut raised a Series A for accounts-receivable automation.
First-order effects
- Stacks gains $23M in new capital, led by Lightspeed, to build and commercialize its accounting-workflow software.
- Accounting teams evaluating automation have another funded vendor targeting work that is traditionally handled through manual finance processes.
Second-order effects
- Rival finance-automation vendors face stronger pressure to prove that their products can connect to existing systems and deliver reliable workflow execution, not merely AI-assisted features.
- As vendors target adjacent finance tasks—from bookkeeping to receivables—buyers may increasingly compare tools by the breadth of workflows they can automate across the finance function.
Third-order effects
- If financing and adoption continue, AI software could shift competition in accounting from point tools toward workflow platforms that capture more of the operational layer around finance teams.
- That shift could reshape entry-level professional-services work by moving routine processing toward software while increasing the value of review, exception handling, and system oversight.
The trend: AI investment is moving from general-purpose assistants toward specialized software that automates discrete, high-volume professional workflows.
