DESAG Deutsche Sachverständigen Gesellschaft mbH

What DESAG Deutsche Sachverständigen Gesellschaft mbH does

DESAG Deutsche Sachverständigen Gesellschaft mbH is a privately held German professional association (Verband) organized as a GmbH and headquartered in Ratingen (with firmographic address listed in Hilden, North Rhine-Westphalia). It operates as a membership-based certification and referral body for freelance expert witnesses (Sachverständige) across Germany, connecting certified practitioners with clients (Auftraggeber) requiring professional appraisals in real estate and construction, automotive and machinery, and IT and data protection.

The association's core products are the Sachverständigen-Verzeichnis (Expert Register), a directory of certified members, and the Gutachter-Vermittlung (Expert Referral Service), which matches clients with suitable experts. Around these, DESAG bundles a member benefits package including professional ID cards, uniform expert seals, certificates, a download area, member discount programs, and personal seal usage on member websites. The association also runs the Sachverständiger Ausbildung (training program) and Weiterbildung (continuing education), with specializations for Kfz-Gutachter (automotive) and Baugutachter (construction). Underlying technology is limited to a website portal functioning as both marketing surface and service directory; no proprietary platform, app, or API is disclosed.

DESAG monetizes primarily through recurring membership fees from certified expert witnesses, supplemented by training and referral-related services. Its go-to-market is community-led, driven by member acquisition and referrals, with client acquisition handled via the website portal, contact forms, phone, email, and WhatsApp. The association holds a core strategic partnership with BSG e.V. (Bundesverband der Sachverständigen), through which it offers members free group membership in BSG e.V. and joint expert seals, and operates a small set of utility partnerships (brutto-netto.de, stempelservice.de, onlineplotten.de, stempel.shop) for member discounts. With only 5 disclosed employees and no disclosed funding, the operation is lean and member-network-scaled rather than capital-intensive.
