What Gross Rechtsanwaltsges. Mbh does

GROSS Rechtsanwaltsgesellschaft mbH is a privately held German law firm (Rechtsanwaltsgesellschaft mbH) headquartered in Berlin and operating exclusively on the landlord and property-owner side of the German real-estate legal market. The firm is structured as a founder-led private limited company under managing director Steffen Groß, with 25 total staff including twelve specialist lawyers (Fachanwälte für Miet- und Wohnungseigentumsrecht). Practice coverage spans residential tenancy law (Wohnraummietrecht), commercial tenancy law (Gewerbemietrecht), condominium property law (Wohnungseigentumsrecht / WEG), and data protection (Datenschutz), serving property owners, landlords, asset managers, residential and commercial property managers, and WEG administrators nationwide across Germany with 130,000+ property units under service and 25,000+ cumulative mandates handled.

The firm operates a documented technology stack built around standardization of high-volume legal work: the app.gross.team online mandate portal enables ~5-minute digital intake with encrypted document submission and electronic signature; Online-Rechtsakte (via e-consult-ag.de) provides clients 24/7 access to electronic case files with automated document distribution; standardized Excel-format legal reports deliver process transparency; and an AI/NLP-driven Mandatschatbot handles initial case categorization and routing. The LEWENTO sub-brand (www.lewento.de) extends the firm into a digital content and training platform offering over 100 MaBV-certified training videos, 200+ legal templates, webinars, and an expert chat. Integration relationships with property-management software vendors (DOMUS, Immoware24), Germany's leading property portal ImmoScout24, the VDIV industry association, and DKB bank drive referral-based client acquisition.

The revenue model is straightforward professional-services hourly billing, explicitly not based on RVG statutory fee scales, with disclosed standardized rates of €238.00/hour (Wohnraummietrecht), €285.60/hour (WEG-Recht), and €345.10/hour (Sonstiges Mietrecht / Datenschutz), all including VAT, supplemented by individual multi-year arrangements for high-volume clients. Add-on revenue streams include debt collection (Forderungsmanagement / Mietinkasso), training seminars, and the LEWENTO knowledge subscription. No revenue, funding, or external investor disclosures are present in the source material.
