What it does
Turning office small talk into a competitive sport. It's prediction markets, but for the stuff that you actually care about - at least not crypto or politics. Just you, your coworkers, and the eternal question: will someone say 'circle back' in today's meeting? Turn your team's daily interactions into a competition.
