About Us

PayByGroup is a proud member of 500 Startups investment family and is based in sunny Mountain View, CA.

We started PayByGroup to scratch our own itch. We’re group organizers. We throw the parties, we plan the ski trips, we lead the rec league sports team.

We understand the hassle of collecting money, the awkwardness of harassing friends to commit, and the all-too-frequent sting of never getting paid back. So we decided to do something about it and help the millions of other people out there in our shoes.
