Even if there isn't a cut-off for adding features to software, there's probably a cut-off for where adding features is the best occupation for the founder. Either the software fails, and its moot, or it takes off, and if it takes off, there is probably a point at which it makes more sense for the founder to leave and work on a new project--one where the hard problems still have to be solved.
