You did it for free? I think this is really cool, but... They're charging for it? Seems reasonable for you and Andrew to get a (smallish) chunk of the revenu

You did it for free? I think this is really cool, but... They're charging for it? Seems reasonable for you and Andrew to get a (smallish) chunk of the revenue or a (reasonable) chunk of the profit. Heck, if you wanted to, you could donate it to charity. But you've effectively donated something pretty valuable to Noah (who is an awesome guy, but already rolling in $ with AppSumo). :-)
