I believe that high-growth companies have a natural biorhythm.
Initial phases of dithering, followed by establishing product/market fit, followed (ideally) by rapid expansion, arriving at some kind of relevant role in the market, however large or small that market may be.
Then followed by an exit or, if you should be so lucky, essentially a restart where the company builds a bigger portfolio for the market or crosses into new markets. All that in a finite amount of time.
Most people and organisations cannot really sustain the level of intensity and attention that is required for this journey for more than 6-7 years. There are exceptions, of course, but less that you think.
Founders, managers, investors would be well advised to remain aware of where they are in the lifecycle in order to gauge accurately how much life energy remains in the corporate batteries.
