The Hidden Driver: Psychological Safety When Code Is Cheap


You don't lose innovation because you lack ideas. You lose it because people don't feel safe to say them out loud, and in Central and Eastern Europe, where questioning the boss or the client's spec often carries a cost, silence is easy to mistake for alignment. Drawing on his book Advantage: Culture and a decade coaching startups, Jaïr Halevi shows why psychological safety, not talent or tooling, decides whether teams question what they're building or just deliver it. That gap matters more now. When AI makes code cheap, building stops being the bottleneck and judgment becomes the product. A team that can't push back will simply ship the wrong thing faster. Jaïr unpacks how power distance shapes feedback, risk-taking and decision-making, and what leaders can do to make candor normal.
