Great venture! I think is a great idea to teach children/ teenagers about finance. You found a pain point, and it is very realistic. My concern is that most of the teenagers are not that concern about financial matters. Parents my like the idea more than the users (teenagers), would they actually use it? As for the elevator pitch, maybe you could have added a voice to your pitch? There were some text on your site that had a small font size, it was not very easy to read.
