Let me explain this with an example. An inventor faces a problem, he decides to develop a solution for it. Initially, he is the main target audience for his invention.
I was wondering if there was an single word to describe this, a word that would mean "to solve your own problem" as a verb or "as a solution to his own problem".
I was thinking at a compound word with the prefix auto perhaps? http://dictionary.reference.com/browse/auto-
EDIT: Example usage: "The developer of the app said it started out as an (...) application (to solve his own problem). Now his company succeeds to target a more broad target audience." Is there one word that can replace the text in brackets?
