NOTOS Xperts GmbH

What NOTOS Xperts GmbH does

NOTOS Xperts GmbH is a privately held German compliance consultancy headquartered at Heidelberger Straße 6, Darmstadt, with a staff of 6 employees. The firm advises B2B clients — spanning large enterprises, mid-market companies, startups, associations, and public entities — on regulatory obligations under DSGVO (GDPR), the EU AI Act, and the Whistleblower Protection Act (HinSchG). Its practice is anchored by Managing Directors Erdem Durmus and Michael Gilmour, both certified data protection officers with prior in-house corporate experience, and co-founder Jens Engelhardt, a triple Fachanwalt (IT law, intellectual property, copyright/media law) with over 25 years of experience. The firm is affiliated with the NOTOS law firm (Wirtschaftskanzlei), enabling it to deliver integrated legal-technical compliance consulting without channel friction between advisor and counsel.

The firm's service portfolio is organized around three practice areas. Datenschutz covers consulting (Datenschutzberatung), structured audits (Datenschutz-Audit), employee and executive training (Datenschutz-Schulung), and the provision of external data protection officers (Externer Datenschutzbeauftragter) for companies lacking internal DPO resources. KI Compliance offers consulting, employee training, and the development of corporate AI usage guidelines aligned with the EU AI Act and DSGVO. Whistleblowing services include the resale and implementation of Formalize whistleblowing software under an official partnership, operation of internal reporting centers (Interne Meldestelle) under HinSchG, and internal investigation support (Interne Ermittlung) with referral to specialized partner law firms for complex legal questions. The firm also uses Zeeg for executive appointment scheduling under an Art. 28 GDPR processing agreement.

NOTOS Xperts generates revenue exclusively through professional services engagements — recurring external DPO retainers, compliance audits, training programs, and project-based consulting — and does not sell proprietary technology products. Pricing is quote-based and not publicly disclosed. The firm is privately held with no disclosed funding rounds, no institutional or venture capital investors, and no parent company; senior governance has been expanded through Prokura granted to four additional executives. Operating geographies are stated as the DACH region and the broader European Union, leveraging the cross-jurisdictional applicability of GDPR and the EU AI Act.
