Builder

Alexandros Riggenbach

I love everything about hackathons and working in an AI-nat · Zurich

I co-founded sprintd, a Swiss innovation sprint engine. We run sprints where companies bring real problems and mixed teams ship working products in a single weekend. Before that I ran START Hack 2026 as Managing Director: 10th edition, 600 builders, a team of 12. At sprintd I own product and ops, and I build our platform myself. Business student at the University of St. Gallen. I see myself as an enabler. We win when the people around us do.
