You should succeed or fail based on the viability of your business model. You should excel if you have generated product/market fit and product/channel fit. If revenue soars, you should not eventually fail because your technology infrastructure cannot cope with the increased traffic and usage that comes with high growth.
This is why establishing a scalable technology infrastructure is one of the five building blocks characterizing a solid FastScaling foundation.
In simple terms, your tech has to be able to handle ten customers, a thousand customers, and a million customers, if you expect to ever get to a million customers.
