Product/market fit can be weak… or strong… or in between.
It also changes over time.

Take the example of BlackBerry.

BlackBerry phones achieved initial product/market fit in the early 2000s. The ability to send and receive emails without a PC was incredible. BlackBerry was the only tool allowing people to do this, which created a lot of value.

BlackBerry’s product/market fit was strongest in the corporate segment. Who more than executives and managers needed to be able to communicate by email anytime, anywhere?

Over the years BlackBerry kept improving the product by introducing new features and strengthening existing ones. Product/market fit was getting stronger and market share was growing.

Everything changed in 2007. iPhone and Android phones burst onto the scene.

The new generation of smartphones was clearly more effective than BlackBerry at most tasks, including email.

With every update to iOS and Android, BlackBerry’s product/market fit got weaker and weaker — first on the consumer market, then on the corporate one. BlackBerry’s added value slid into freefall.

In a few years BlackBerry was so far behind that it had nothing to offer anymore. Product/market fit was gone.

BlackBerry serves as a cautionary tale of how product/market fit changes and can even disappear entirely.

BlackBerry’s product/market fit was strongest in the corporate segment. Who more than executives and managers needed to be able to communicate by email anytime, anywhere?
