Senior🎓
Top SchoolLukas Klein is a founder and CTO with 14 years of experience building connected-device platforms and product companies from idea to market. As co-founder of Datacake he leads engineering on IoT connectivity and device integration, bringing hands-on full-stack experience honed since early web developer roles and internships at DataSift and SAP. He pairs technical leadership with product-minded execution through Product Gang, helping visionaries turn concepts into investor-ready, live products.

Based in Münster, Germany, he favors pragmatic, real-time architectures and has deep familiarity with Node.js, websockets, and data-driven visualisations from his early projects.
