Well, revenue is a beautiful thing, certainly. You can define product/market fit however you like-- but by that definition, most consumer apps don't have it.

Well, revenue is a beautiful thing, certainly. You can define product/market fit however you like-- but by that definition, most consumer apps don't have it. A customer can "buy" a product with money or their time/attention. I'd say both YouTube and Facebook have found a great product/market fit. And Gmail. Andreessen found a great product/market fit with the Netscape browser, but monetization of it really only came in the form of a few bizdev deals (which didn't cover costs, I don't think). Money, in many of these iconic companies, was NOT piling up. Regarding my company, we focused initially on a non-paying market (individual lifehackers), as that was easiest to build for and launch a rough beta for. They "pay" in blog posts, tweets, word of mouth-- they've driven every single business lead we've gotten. Now we've got a new market (teams) that we have to find a "fit" for. Wish us luck!
