One alumni told me that YC was all about picking billion dollar, not million dollar businesses. In that case, could you say juniper would scale to the billion dollar market? Could your users track their usage with a recurring Google calendar entry? (I know women that do). Why not scale to include other high usage products - toothpaste, toilet paper, etc? (I know of one startup in stealth mode doing this, so it's probably a feasible plan). Sorry for playing devil's advocate - really like what you got so far though.
