Why this exists
Most kids get told to wait until they're older to build something real.
Younger kids come up with some of the best and most creative ideas all the time, then get handed a worksheet about entrepreneurship instead of an actual shot at building one. Somewhere between "that's a great idea!" and being taken seriously, most kids get the message that big thinking is for later.
Sandbox Studios exists because that gap is fixable right now, not someday. Give a kid ten days, a few people to test their idea on, and a room that isn't obligated to clap for them, and they'll build something that actually works. Not a pretend version of entrepreneurship.
The mission isn't to make every kid start a company. It's to prove to them, early, while it's still cheap to fail, that their big ideas are allowed to leave their notebook.
