€1.8m · Other round · AI · Milan, Italy
Milan-based Rulen, formerly LexSA, has raised €1.8m in its first funding round to develop its AI platform for tax and accounting work and expand commercially. VC Partners led the round, with Growth Engine, AME Ventures, Zest through its Magic Mind vehicle, Alpha Venture and sector business angels participating. According to the participating-investor announcement, Rulen plans to add about 10 people by the end of 2026 across sales, marketing, product and tax expertise.
Moving from tax answers to completed workflows
Rulen is designed for accountants, tax lawyers, in-house tax teams and professional-services groups whose work crosses regulations, client documents and several existing software systems. Its product combines a proprietary tax knowledge base with customer-controlled documents and workflow templates, then links those materials to tasks such as research, calculations, reconciliations, document drafting and review.
The company says the platform integrates with Italy's Cassetto Fiscale as well as Excel, OneDrive, email and Word. That matters because a tax assistant that only produces an answer still leaves a professional to move data between systems, check the source, prepare the document and record the decision. Rulen's commercial proposition is to automate more of that chain while keeping verification and final judgement with the practitioner.
Embedding the product inside the tools a firm already uses can reduce adoption friction and make each automated workflow more valuable than a standalone chat interface. It also raises the execution bar. Tax rules change, client data is sensitive and an error can carry legal or financial consequences. Rulen therefore has to show that integrations, source traceability and approval points remain dependable as its agents take on more operational steps.
Domain expertise has to scale with the software
The funding coincides with the rebrand from LexSA, which the company presents as a shift from research assistant to operating platform. Zest reports that Rulen quintupled its customer count over the preceding three and a half months and now processes thousands of tasks daily, with use across law and tax firms, professional-practice consolidators and multinational groups. These are company and investor claims, but they indicate the breadth of workflows the new team will need to support.
Hiring tax specialists alongside engineers is central to that expansion. Domain experts can encode workflows, review regulatory changes and define where human approval remains necessary; engineers can turn those patterns into repeatable product features. The commercial test is whether Rulen can reuse that work across customers without becoming a bespoke consulting service for every firm.
If it succeeds, the platform can help practices serve more clients without adding staff in direct proportion to workload. The constraint is equally specific: automation creates leverage only when the tax knowledge, customer context and system integrations stay current enough that professionals trust the output. The round gives Rulen room to build both sides of that product, rather than treating domain review as an afterthought.
