I think this is awesome in terms of a product. Could be interesting to expand to other types of recalls (just go through the Ralph Nader list). Most of this information is publicly available, but in such shitty databases that it's not even worth pursuing. If I was a parent, I'd definitely sign up and probably pay a low amount.

Also, if you want some free help tracking your subscription metrics for Stripe, feel free to check out profitwell.com (completely free). Would love your feedback on that as well, if you don't mind. :)
