"I'm more interested in how this person got celebrities and billionaires interested in the product early on. Seems odd."
Ding ding ding! That's my real issue with stories like this. They don't explain how these young geniuses got capitol to build their ideas or how they were able to market them to people with influence or how they are able to convince influencers like Marissa Meyer to fork over $30 million.
Not hating on the kid, but without proper explanation of those three aforementioned things, there's no real story here.
