What Digistore24 says aboutworking with Sebastian.
This personal account was recorded at the Digistore24 MVP event2025 in Singapore. In the video, you'll hear directly from Sven.
“I see a lot of AI ideas. What's different about Sebastian is that he thinks them through all the way to the product, the customer result and the business model.”That's rare. And it's becoming more valuable all the time.

Munich · 2026An earlier live format
A look back
At some point, the idea has to become something a customer can try.
At Firestarter Munich, entrepreneurs turned their expertise into their first personal AI products. That format is no longer the main focus. Its core lives on in the Golden Ticket: first clarify the result and demand, then build something people can experience with CoachWunder.
Customer stories
What working togetherchanged for people.
„Sebastian came into our lives and helped us really move from self-employment to being business owners and building a team. To delegate work and outsource processes, and simply build a system.“
„Why did I choose Sebastian? Because I trust him deeply, and he gave me the guidance and structure I had been missing. Before that, I couldn't see the forest for the trees.“
„That really inspired me and showed me just HOW extensively you can and should now bring AI into your business!“
„Honestly, I'm so excited I can barely sleep. These tools are incredible, and I'm realizing how many projects I've had in my head for so long I can finally bring to life, with a fraction of the effort they used to take.“
„The workshop really showed me the potential of artificial intelligence in everyday business. As an entrepreneur, I was especially fascinated by the vision of waking up with an idea and letting AI handle the entire process of bringing it to life, right through to the first sales that evening.“
„The AI coach is getting a great response: just 1 hour after opening, we already have over 120 interested people on the waiting list.“
