WePay started with a simple idea: an app that made it easy for friends to pool money for shared expenses like ski trips and club activities. Yet that simple idea wasn’t so simple to execute. It was 2008, and no payments system could easily and safely pool money from groups of people to pay out to others. So we built one. The team spent nearly two years negotiating contracts, dealing with regulators, and wrestling with bank integrations. We developed easy sign-up and frictionless checkout experiences. We also built one of the most advanced fraud detections systems around so we wouldn’t lose our shirts.
