The most successful (profitable) YC "products", Heroku, Dropbox and Airbnb, have very sound business models with tens of thousands of customers that are not "traditional corporations".
Is the fact that Heroku was acquired the rationale for calling it the 'product' purchased by 'traditional corporations'? If so, what threshold would you apply for when a company can be considered successful before it gets acquired? As companies of all sizes get acquired, aren't they all then 'product' that wasn't successful until a real company bought them?
