Selling a magical pill without providing pharmacology is no different than selling snakeoil. Share your solution please, unless that part in your question is just a digression; (addendum) does not seem to be the case from the last paragraph.

To answer your question, it depends. Anecdotally, we created custom solution for analytics for our Robot, and then moved it in as a solution. You can think of it like 'internal-pivot'.

Additionally, in-house tools, if designed correctly, are usually small pieces of software that do just what a company needs. Tailored solutions, if effectively created, are sometimes better than something out of the box. It also lets the developers stay stimulated when there is not 'actual work' to be done and adds potential for features to be implemented for their product; if not providing with something they can pivot and sell separately.
