“Can an AI-native collaboration layer on top of DATEV become the default operating system for German tax firms?”
milia.io is a vertical SaaS collaboration + AI-assistant platform purpose-built for German DATEV tax advisory firms (Steuerkanzleien). Founded 2021 in Cologne, the product orients around DATEV integration (DMS, Unternehmen Online, Rechnungswesen, Meine Steuern, Personalakte) rather than being accounting software itself — it explicitly leaves the tax/bookkeeping work to DATEV and automates workflow, client collaboration, document exchange, and routine processes around it. In 2025 the company was acquired by Visma, placing it inside Europe's largest accounting/business-software group alongside Visma's broader DACH tax tech portfolio.
milia.io integrates with DATEV.
milia.io was founded by Michel Menk and Tilman Walch and is founded in 2021, headquartered in Cologne, Germany.
