Be wary of the hype (cycle)
Every product goes through multiple stages, they are sometimes called the Gartner Hype Cycle. While it might not be scientifically proven to be true, it has its worth as a handy metaphor.
The diagram incapsulates neatly different stages of product and technology awareness: how at first, almost nobody even knows about the product, and by the end of the timeline it is usually a given that the product exists and proven to work.
The tricky part is in the left side of the diagram. Firstly, when there is not enough data, it is hard to reliably predict whether the product will get traction at all. This is sort of a trial by fire for the new entrepreneurs. Those who survive this come to the second part.
If the product has proven to work, now is the time to build it out and scale. This is where it is tempting to succumb to the hype, rake in as much money as you can while it lasts. However, this is not a sustainable way to grow.
At this stage it is easy to go off the path and sabotage yourself and the business, ruining the reputation by over-promising and under-delivering.
One such success story is the game No Man's Sky, where it was hyped beyond the studios capability and resources, which resulted in a hit towards reputation.
Not all was lost, however. And that studio managed to recover. What they did is to admit their mistake, they went silent and kept working, ironing out their mistakes. It took a while and the hype has been long gone, but they managed to recover and stabilise.
Looking at the chart above, the "trough of disillusionment" for them has grand.
So, in my opinion, we shall strive to find the middle ground between overhyping and underperforming. We shall strive towards the "plateau of productivity".
