Great point.

Interestingly, I see several tech startups of this nature started by folks having a deep understanding of a specific business problem due to their prior work experience tend to create such startups.

As a service provider for small businesses, I see many amazing bootstrapped services & products come up around the world, that serves a very specific need for a small subset of customers. These viable businesses tend to make enough for the needs of 2-3 folks for a long time. I have a strong inclination towards finding many of them as a service provider because they just tend to be some of the best customers with great ROI.
