Product Market Fit isn’t static. You need to evolve, not to be disrupted by competition, changing market or consumer sentiment. Remember HipChat (Slack) or Adobe Creative Cloud (Figma)?
There isn’t an end to this process, so keeping it going it’s the most crucial one of being a Product Leader. Depending on your company situation or growth phase, it requires a unique mix of operational or strategic work. So never, ending learning, staying open and experimenting just to stay in place.
Nobody said that it would be easy.
