Link based selling has been around for years. 2checkout, 1shoppingcart, ejunkie etc...
I started working on Chec in late 2010/early 2011, before groad launched. (https://www.facebook.com/checkoutbyswipe, if you wanna trace down to the day that page was setup) - It's a long story between then and today.
Short Version - University in England -> AngelPad Incubator -> Raised large seed -> Founder Split -> Had to rebuild new company.
