What Fideus does

Fideus GmbH is a Berlin-based TaxTech company that provides automated annual financial statement preparation and tax advisory services exclusively for German holding companies (GmbH and UG legal forms). The platform combines a self-serve web application at app.fideus.de with licensed tax advisory delivered through a strategic partnership with TechTax Steuerberatungsgesellschaft mbH (50+ staff, 7+ tax advisors). Fideus's own team of 5, including three co-founders — Daniel Bartholomae (Product/Tech), Kai Klapal (Managing Director, Growth), and Lennart Friedrich (Tax Operations) — operates primarily remotely and focuses on product development and customer acquisition, while TechTax executes the regulated tax filings, authority communications, and Bundesanzeiger disclosures.

The core product is the Fideus platform, which provides automated bookkeeping with transaction categorization, multi-holding dashboards, digital document management, e-balance sheet preparation, and tracking of deadlines and tax authority correspondence. Services are sold as fixed-price annual subscriptions: Holding Lite at €600/year covers up to 3 holdings, 40 bookkeeping transactions, balance sheets up to €150,000, corporate and trade tax returns, and authority communication; Holding Pro at €1,500/year adds VAT annual returns and advance notifications for active holdings. Add-ons for additional transactions, holdings, higher balance sheets, consulting, and dividends are priced on request, with multi-year contracts available for the add-on bundle.

Fideus serves founders, serial entrepreneurs, and business angels in the DACH region, with 500+ holdings reportedly under management and customer ratings of 4.8/5 on Google and 4.7/5 on Trustpilot. Distribution combines a product-led self-serve flow (quote generation in under 2 minutes) with a Calendly-based sales-assisted motion for larger holding structures. Marketing relies on SEO, an educational 'Wissen' content section, LinkedIn, and earned media coverage in Startbase, Manager Magazin, Finance Forward, and Deutsche Startups. The company is GDPR-compliant, registered as Fideus GmbH in Berlin, and operates without disclosed external funding.
