Founded in 2024 in Berlin by Kai Klapal, Lennart Friedrich and Daniel Bartholomae, Fideus is building a TaxTech platform designed specifically for founder- and investor-led holding structures. The software combines conversational AI and agentic systems to automate recurring tasks such as deadline tracking, document matching and open-item reconciliation, while giving both entrepreneurs and tax firms shared, real-time access to data. In the next product stages, Fideus plans to embed tax advisors directly into the digital workflows and later add modules for asset management, real estate administration and treasury. The company is already running initial automated processes via a partner tax firm that services more than 200 customer holdings, demonstrating early market traction. By focusing on excellent user experience for entrepreneurs and structured hand-offs into advisory systems, Fideus aims to reduce manual effort and increase transparency in annual-accounts preparation. The recently secured capital will be devoted primarily to expanding the product’s AI-driven workflow engine, pattern recognition and collaboration features.
