They were a YC company, weren't they? Ivan and Abby?
They were. Ivan's now at Facebook, where everyone assumes he's working on Facebook Payments. Abby's probably doing something even cooler, although IDK.
BTW, Tipjoy never held the money; they were just a front-end for PayPal, so they didn't have the issues that Fundable apparently is having.
Tipjoy never held the money
That does not match with my understanding of their business model.
Look for their instructions on, e.g., cashing out.
[Edited to add: Tipjoy. I knew it was T-something but I ran through about 15 combinations of Twit-X before realizing that it was not from that naming convention.]
