Stefan Knop is a Hamburg-based founder and product-minded software engineer with five years of focused startup leadership, currently running rubberduck studio and building kwizkid while freelancing as a web developer and interface designer. He founded asap.industries (acquired by XING and relaunched as HalloFreelancer), demonstrating an ability to take B2B marketplace ideas from concept to successful exit. Combining UI/UX design training from HTK Hamburg with hands-on development, he ships pragmatic, user-centered web products. Stefan blends creative design instincts with founder-level product strategy, and quietly prefers building lean, revenue-focused tools over flashy tech for its own sake.
