What Cassini Consulting AG does

Cassini Consulting AG is a privately held German management and technology consulting firm headquartered in Dortmund, founded in 2006. It operates as an independent consultancy — explicitly without vendor or product affiliations — and delivers digital transformation, IT security, and organizational change advisory to three primary client segments: the German Mittelstand, large corporations (including DAX-listed firms), and the public sector (federal ministries, state chancelleries, and municipalities). Service coverage spans strategy formulation through implementation, including IT strategy and governance, agile transformation, cloud strategy (Cloud-Kompass), cybersecurity (with dedicated NIS-2 and ISO 27001-backed practices), supply chain due diligence under the LkSG, data science and AI advisory, sustainability management, commerce excellence, digital marketing and sales, and project/process management.

The firm is organized around a partner-led delivery model, with senior partners and domain leads publicly listed alongside service pages. It maintains eight physical offices across Dortmund, Düsseldorf, Berlin, Hamburg, Köln, Frankfurt am Main, Stuttgart, and München, enabling national field-sales coverage of German clients. The company holds ISO 9001, ISO 14001, and ISO 27001 certifications, is consistently ranked in the Lünendonk Top 20 Managementberatungen and Top 15 eGovernment-Berater lists, and has been recognized by BrandEins, kununu, Fair Company, and Top Consultant. Public-sector clients include the Bundesministerium des Innern (BMI), the Auswärtiges Amt, the BDBOS, the Staatskanzleien of Schleswig-Holstein and Brandenburg, the NRW Ministry for Economic Affairs, Landeshauptstadt München, and Stadt Wetzlar, among others.

Cassini generates revenue exclusively through professional services engagements — typically project- or retainer-based — sold via direct, consultative enterprise field sales and a free initial consultation (kostenlose Erstberatung). Public-sector work is additionally accessed through framework agreements including the BVA 3-Partner-Modell / Kaufhaus des Bundes and equivalents with NRW, Bayern, and Sachsen. The firm has no disclosed parent company, no external institutional investment, no subsidiaries, and no M&A activity in the source material. Management is provided by a four-member Vorstand (Piet Affeldt, Jan-Lars Bey, Dr. André Stebens, Dr. Oliver van Laak) plus a COO (Michael Seipel); the founder, Sven Wiedenhofer, continues in a Senior Partner role. The company explicitly discloses no proprietary technology platform, software, or algorithmic IP — competitive advantage derives from consulting methodology, regulatory expertise, partner bench, and brand reputation rather than from technology assets.
