Summary
👤
Senior🎓
Top SchoolJohan Sellström is a seasoned serial founder and technologist with 15+ years leading startups and ventures across health tech, identity systems and internet platforms from Stockholm. He co-founded and advises multiple companies (Svipe, Infrion, Vagus Health, CareChain, Advatar and others) and has a long track record of turning conceptual missions—often described as “mission impossible”—into working products and infrastructures. His background in engineering physics and early work on high-performance visualization and CFD tools give him deep systems thinking and a preference for pragmatic, cross-environment programming. Johan also contributes to standards for personal identification (SIS/TK 448), blending entrepreneurial pragmatism with governance and interoperability concerns. Not obvious from titles: he repeatedly bridges research, industry and product by spinning incubated concepts into commercial ventures and infrastructure for managing personal health data.
