It’s not easy finding a short answer to the question. A company could offer general ITs solutions to all of its target industries but claims to ‘specialize them’ for its ‘unique requirements.’ Likewise, a specialist company could in fact be offering a general solution that is just ‘exclusive’ for a particular industry.
But before you start going insane from figuring this out, stay calm. There is a reason why having a variety of IT leads can be a good thing, regardless of how you go about appealing to each different buyer personas.
