This sounds like one of those words that have been used by marketers to massage their ego for a really long time.
Unfortunately, innovators, entrepreneurs, and creators have failed to see how this “pRoDucT mArkEt fiT” can trap them into thinking there’s a market they need to fit their product or service into.
