Does RunDeck keep a log of every response? With Commando.io you can flip back through previous executions and see a snapshot of which servers got which recipe, and what the results were.
It definitely does: when I launch a job in RunDeck, I can see the live output (essentially a form of tail -f in the RunDeck web interface) and I can see the output of every previous job as well.
I don't want to seem rude, but I really am amazed that you've got to the point of asking people for money without bothering to research existing potential competitors.
I'm not saying your product doesn't have differences to things like Rundeck that might set it apart; but, as a potential backer, the lack of research is a bad smell IMO.
