I remember the very day that PG, Khaled, and James sat down in 2012 and defined the future of Tilt. Amazingly exciting to see how it's grown since. I love that the nicest founders in our batch are doing the best :)
A client came to me about 10 years ago and wanted me to build an app that let individuals collect money from a group. (In their case for wedding gifts). I told them they were crazy because it would get taken over by fraudsters trying to cash out on stolen credit cards and PayPal accounts.
Another lesson for me I guess for being overly cautious instead of coming up with solutions. I'm glad to see people have figured out how to make these things work. Of course at the time you had to legally offer your right arm and your first born to get a merchant account.
