What Thamm does
Thamm (legally André Thamm (Dipl.-Psych.), sole proprietorship, VAT ID DE292804551) is a psychologically-grounded management consultancy headquartered at Liebigstraße 29, 49074 Osnabrück, Germany. Founded in 2002 by Diplom-Psychologe André Thamm and in regular operations since 2005, the firm delivers organizational and personnel development services to companies, executives, and individuals across Germany, operating both in-person and online nationwide.
The core offering is organized into four service lines: Organisationsentwicklung (organizational development and change management), Seminare & Workshops (leadership, communication, team, stress, and New Work training), Individuelles Coaching (one-on-one coaching), and Diagnostik & Personalauswahl (assessment centers, development centers, and psychometric testing). All services are delivered by psychologists and certified coaches using scientifically-grounded methods, with content tailored to each client's culture and needs. A separate sub-brand, //thamm campus (thammcampus.de), packages adapted seminars for university students and staff. There is no proprietary technology platform; delivery relies on standard digital meeting tools for online formats and conventional in-person facilitation.
Thamm is a bootstrapped, founder-owned sole proprietorship with 11–50 employees, no external investors, and no parent entity. Go-to-market is sales-led and consultative, driven primarily by inbound inquiries through the company website, direct contact via phone and email, and organic social channels (LinkedIn, Instagram, Facebook) maintained since November 2023. Pricing is not publicly disclosed; engagements are individually scoped after a needs assessment conversation. Revenue is not reported in available sources.
