A Selection of Projects (alphabetical)

My Wall of Projects

Over the past two decades I’ve worked with more than 600 teams — startups, SMBs and corporates — on business models, technology, financial planning and growth. Some were still looking for a model that works; many already had one and came to scale it. The wall below is a selection: the 204 companies, accelerators, incubators and universities I can show here by name, in alphabetical order.

We are very happy to work with Arndt as a jury member in our start-up pitch. He does not only have a lot of know-how about digital business models, but also broad experience and people knowledge in the start-up environment. He instinctively asks the right questions and puts his finger in the wound when things do not add up.

Working with Arndt is always fun. In his workshops for startup teams, he shares many experiences and links them to messages. He has many creative ideas based on his own ramified experiences or resulting from the manifold consultations with start-ups. His assessments are honest and constructive.

We started working with Arndt 8 years ago and have regularly sought his help ever since. He has helped us prioritise, challenge our business model (CAC vs. CLV) and refine our go-to-market strategy. Arndt has been a mentor, coach and friend. We can highly recommend him to any digital start-up.

Arndt's talk at Tech Quartier was truly enlightening! Even following the lecture from the stream, I was very excited. In just 3 hours, Arndt taught me more than I learned during an entire semester of finance in business studies. I feel empowered and equipped with new insights.
