Igor Vainshtein has started 20 businesses — 18 of them failed. But out of those failures came a sold company, a globally scaling golf tech app, and a move to the US to build something big.

In this episode of Flow Zone, Igor sits down with Mark to break down the real cost of entrepreneurship: the $5M business lost overnight on New Year's Eve, getting wiped out by Lehman Brothers, having a Google ad account wrongly suspended during peak season, and what each of those moments actually taught him.

From how AI and personal brand are reshaping what's possible for founders, to why Igor is betting everything on the US market again — and what happened the last time he made that move — this is one of the most honest conversations about failure, resilience, and building for the long game you'll hear all year.
