As a kid, he says he would peruse the sites and ask for help where he needed it, only to be met with constant criticism from members of the community.

"People would say, 'You don't know how to do that? What are you like 10 years old?' and I was like 'Yeah. I am,'" Klein remembers.

Klein never felt that there was an easy entry point for a curious kid to get involved in technology, and so, last year, he decided to create one himself. He launched Kano, a kid-focused computer company that not only teaches young people to code but also how to build their own computers. Kano launched on Kickstarter in 2013 and has since sold 40,000 kits to users around the world. Last week, Klein announced the company had raised $15 million in venture funding.
