Senior🎓
Top SchoolAlexander Lang is a seasoned technology leader and co-founder with 17 years of experience building products and communities from Berlin, currently serving as CTO of Cobot where he helps coworking and flex spaces streamline operations worldwide. He combines hands-on engineering roots—evidenced by contributions to well-known projects like mustache.js test suites—with strategic product leadership that grew Cobot from consultancy origins into a focused SaaS product. A persistent builder of community infrastructure, he also co-founded co.up, a Kreuzberg hotspot that seeded local initiatives like Rails Girls and Open Tech School. Pragmatic and people-focused, he bridges technical debt reduction, test automation, and product-driven roadmaps while staying involved in code and QA work. Outside work he’s an offbeat maker—building a sailboat, commuting by cargobike, and openly disliking the home office—bringing a candid, humorous leadership style that keeps teams grounded.
