Its the one thing that really needs to be true. I've met many entrepreneurs and although chaos is usually something that impedes a company it's not always true. I know people with decades old multi million dollar profit companies and you see behind the curtain and its literally a mess. I know companies that do zero advertisement and are doing year over year growth. I see companies that are extremely unfriendly to their customers but deliver a product that they cant get somewhere else... The only real thing that connects all these companies is that they are selling something people want.

I tend to agree - just look at large parts of the Venture Capital / Start-Up scene. Chasing the coveted product/market-fit is a purpose in itself there (at least in the early stages). I guess it depends on what you define as "successful"...
