“If I received a nickel for every time someone asked me, “How is LinkedIn going to make money?” during those days I probably wouldn’t have needed another revenue model! But I knew that we should ignore that fire, because (1) the lack of revenue wasn’t going to be the proximate cause of death unless it prevented us from raising money and (2) the product fire was far more urgent and required our focused attention. If we couldn’t find the distribution to acquire a critical mass of at least a million users, and build a product they found compelling enough to become regular users of the service (or at least respond to LinkedIn requests), the revenue model would be irrelevant.”
