Leandro Utz is the founder of VibeWin (vibewin.app), a tool that scores live giveaways and sweepstakes on your real odds of winning, prize value, and entry effort. He built it on his own and has analyzed thousands of live giveaways, so he can speak to how sweepstakes odds really work, how to estimate a prize's real value, how to spot fake or scam giveaways, and whether entering is actually worth your time. He can also talk about building a product solo, from data collection to launch.
