Disclaimer: we write recruitment software.

Virtually every recruitment tool in existence already does this. Any company that doesn't send a"sorry" email to applicants is either not using any technology at the point of screening (unusual for anyone of any size) or has a screwed up recruitment process (common in large companies).

You'll need to find other secret sauce.

Your goal could be to find a way to encourage managers/recruiters to provide more genuine feedback.

How about tiered responses, and tools to track and prompt when the tiers are not being used correctly?
