About Jonas

I've been in the software startup scene for over ten years. I've worked as a developer, product manager, and CTO, and founded my own companies. This combination is my unique selling proposition: I understand your product, your business model, and your code — and I can cover it all in one person.

What I do for you:
  • Sharpen the product: Together, we'll transform your idea into a clear, focused product. What belongs in it, what gets cut, what's the shortest path to validation? This is exactly where my strength lies — I've already helped many founders nail their concept.
  • Development with AI: I develop with AI, meaning I consistently use modern AI tools in the development workflow. For you, this means significantly faster implementation without loss of quality.
  • Design & UX: I have an eye for what makes products feel right, so users stick around. No separate designer needed.
  • Full Stack including Deployment: From the first line of code to live operation in production — everything from a single source.
  • Sparring Partner at Eye Level: I take on the role of a temporary technical co-founder. We discuss decisions, I challenge your assumptions, and together we find the best way forward.

All of this massively reduces your communication and working effort and gets you to the point where your product has real users faster.
