Episode description:

Lean Stein is the co-founder of Avento, a vertical marketplace for extreme sports equipment - starting with skydiving. His path to entrepreneurship is anything but linear: he dropped out of high school, did an apprenticeship in private banking in Basel, then went to the University of St. Gallen to study economics. This is where he ran into START Global - Europe's leading student initiative for new technologies and entrepreneurship.

Lean breaks down what he learned from START Global that directly translated into building a company: learning by doing - getting real responsibility early (budgets, partners, execution); building founder-grade habits like structure, prioritization, and the confidence to reach out (and handle rejection); and developing startup judgment - seeing lots of pitches and ideas to better spot what’s worth building and what isn’t.

He also opens up about his personal journey: how buying faulty secondhand skydiving gear became the trigger for Avento, the reality that early-stage building is a workload that “never stops” - but can still be fun when you’re doing it with a co-Founder, and the mindset shift that surprised him most: you can learn hard skills faster than you think - even coding - once you commit to starting.
