What solidaris unternehmensgruppe does

Solidaris Unternehmensgruppe is a privately held German professional services firm founded in 1930 and headquartered in Cologne, operating under a multi-entity partnership structure (Solidaris Revisions-GmbH, Solidaris Treuhand-GmbH, Solidaris Rechtsanwaltsgesellschaft mbH, and Solidaris Unternehmensberatungs-GmbH). The firm delivers an integrated 360-degree advisory offering across five service lines — Wirtschaftsprüfung (auditing), Steuerberatung (tax consulting), Rechtsberatung (legal advisory), Unternehmensberatung (management consulting), and IT-Beratung (IT consulting) — exclusively to the German healthcare and social economy (Gesundheits- und Sozialwirtschaft).

Its target segments span seven verticals: elderly care (Altenhilfe), integration assistance (Eingliederungshilfe), hospitals and health facilities (Krankenhäuser und Gesundheitseinrichtungen), child and youth welfare / education (Kinder- und Jugendhilfe/Bildung), churches and associations (Kirche und Verbände), non-profit organisations, and the public sector. The firm competes on 90+ years of accumulated sector specialisation, deep familiarity with complex German regulations (Heimrecht, SGB V–XII, BTHG, Gemeinnützigkeitsrecht, church labour law), and integrated cross-disciplinary mandates that allow clients to consolidate multiple advisory needs with a single firm. Supporting offerings include a benchmarking tool (Benchmark.Solidaris), practical work aids (Arbeitshilfen), a hospital crisis hotline for Krankenhausreform queries, recurring seminars/webinars, and a client newsletter/journal.

The technology footprint is conventional: a TYPO3 CMS website with standard marketing integrations (Google Analytics, Google Tag Manager, HubSpot, CleverReach for newsletters, LinkedIn Insight Tag, Google Marketing Platform/DoubleClick). No proprietary software platform, API, or AI/ML product is described. Distribution is entirely B2B direct — sales-led, project-based or retainer engagement, with no self-service or marketplace channels — and pricing follows German statutory fee schedules (e.g., StBVV) for tax and audit work, with bespoke fees for consulting mandates. Geographic reach is single-country (Germany) across ten offices (Cologne HQ plus Berlin, Erfurt, Freiburg, Hamburg, Mainz, Munich, Münster, Stuttgart, Würzburg).
