You can't tell much from the numbers of a startup this young. They've generated more revenue than Google had at the same age.
Can TipJoy get big enough fast enough?
Well, that changes things. :-)
You can give far more than $0.10. That is just the default. It is really simple to give up to $10, and we might raise or remove that limit.
Also, we earn interest on money in our system. That makes the earnings closer to 6%. But we don't take a cut per tip, only on cash-out. This means that if A tips B who then tips C, each of those tips is overhead free. If C cashes out, we take a cut. The potential for a zero overhead transaction system is huge.
But that's not a really good comparison especially if Tipjoy is dealing directly in money while google was search. Having said that, maybe Tipjoy is onto something because the last micro-payment startup to do something interesting was paypal which started 10 years ago.
