What makes us a team

Hands-on occupational safety

With Kim, an occupational safety specialist is part of the founding team. Requirements from everyday operations flow straight into product development.

Software experience for web and mobile

Frank and Lukas bring experience from development at SAP and as a solution architect in the Sparkassen-Finanzgruppe – for the web app and mobile app from a single source.

Strategy & solid funding

Benjamin is responsible for strategy and finance. AMS Go is backed by Start-up BW Pre-Seed funding and business angel Dr. Friedrich Hoepfner.

Dr. Friedrich Hoepfner – entrepreneur, start-up promoter and business angel

With Dr. Friedrich Georg Hoepfner, we have one of Karlsruhe's best-known entrepreneurs and investors on our side. For decades, he ran the Hoepfner private brewery in the sixth generation, and with CyberForum he founded a platform for start-ups, entrepreneurs, IT providers and research institutions that has supported thousands of founders.

What he has achieved

  1. DecadesRan the Hoepfner private brewery in Karlsruhe in the sixth generation
  2. CyberForumFounder of CyberForum and partner of the IT accelerator CyberLab, the Digital Hub network and “KI-Transfer BW”
  3. 2008Founded the Hoepfner Foundation, which supports young entrepreneurs as well as art and culture
  4. 2010Named “Business Angel of the Year” by the Business Angels Network Germany (BAND)
  5. 2022Officer's Cross of the Order of Merit of the Federal Republic of Germany, presented by Minister President Winfried Kretschmann
  6. 2026Invested in AMS Go GmbH as a business angel

Why he is the right business angel for us

Dr. Hoepfner knows both worlds that AMS Go brings together: as the long-time head of a family-owned manufacturing business, he knows how small and mid-sized companies work – and as the founder of CyberForum, he has been driving digital innovation in the region for many years. He supports start-ups not only with capital, but as a sparring partner on strategy, sales and financing, and with his network.

Through Hoepfner HI-TECH Beteiligungs GmbH, he is also the co-investor in our financing under L-Bank's Start-up BW Pre-Seed program. In this early-stage program of the state of Baden-Württemberg, a private co-investor complements the state's funding. This is how public funding, private capital and entrepreneurial experience come together for us.
