What Stollfuß Medien does

Stollfuß Medien is a German professional publisher specializing in tax law and adjacent legal areas, operating as a branch (Zweigniederlassung) of Lefebvre GmbH under the Lefebvre Group (formerly Lefebvre Sarrut) umbrella. The company curates and distributes a comprehensive portfolio of expert-authored legal content — including tax law commentaries on the Einkommensteuergesetz, Körperschaftsteuergesetz, Umsatzsteuergesetz, Abgabenordnung, Erbschaftsteuergesetz, Zollrecht, and Umwandlungsrecht — alongside professional journals (Deutsche Steuer-Zeitung, Die Steuerberatung, EFG, HFR, B+P, UVR, ZfZ, ZKF), loose-leaf reference works (Loseblattwerke), handbooks, and practice aids. Its primary customer base comprises German tax advisors and auditors, with secondary segments including lawyers/notaries, payroll offices, financial accountants, corporate tax departments, and public institutions.

The technology stack overlays this curated content corpus with proprietary AI: GenIA-L Steuer-KI, marketed with the PromptPerfection® prompting methodology, provides AI-augmented answers to tax law questions and is offered at €99 for a 3-month trial subscription. Stollfuß also distributes the juris KI-Suite, an integrated AI-assisted legal research suite, through its own storefront and via the juris.de portal under the juris Allianzwiderstrebend partnership. AI capabilities focus on text-based knowledge retrieval and generation over German tax and legal content.

The business model is subscription-led and recurring: most revenue comes from annual subscriptions covering tax law commentaries, loose-leaf works, journals, and online database access (Fachportale/Fachmodule), typically on 12-month minimum terms with 6-week cancellation notice. One-time book sales occur through the e-commerce storefront under German book price binding law (Buchpreisbindungsgesetz), and enterprise online-database access is sold via quote-based named-user licensing with a 98% annual uptime guarantee. Go-to-market is sales-led, combining direct e-commerce (stollfuss.de), inside sales via phone and email, distribution through German trade bookshops and barsortiment wholesale, and the juris.de marketplace. Marketing relies on SEO-optimized content, newsletters, XING/LinkedIn presence, ESG whitepapers, and events targeting professional tax and legal practitioners in the DACH region.
