In evaluating a B2B niche services business, what's the best way to do market research? Google searches for this service only yield large players that cater to large companies - this particular company provides services to small business in a niche sector. I have also tried to find industry associations, but no luck, I am trying to assess the competition in this seemingly fragmented market. I have a hunch that the customers may be in-sourcing this service. What's the best way to verify it?
