Investors' worst nightmare is if you just make enough money to keep going, but you don't grow ("lifestyle business" as they use it is a derogatory term).
That's because they prefer a sudden death where they can write down the investment and deduct their loss from taxes than an investment where they never see any money again.
And then there are "acquisitions" that are really "acui-hires" dressed up as acquisitions to get the people (more common) or to buy an asset in a limited shell package (less common) after things did/may have (but people were to tempted to take the offer) or did not pan/panned out. Some people consider anything <$50m as a "failure", because that's roughly the sum that many corporations can spend without calling the bigshots for a board meeting to decide.
