Zach Sims, CEO and Co-Founder of Codecademy, discusses the company's purpose: To help everyone around the globe learn the technical skills they need to find jobs - at little or no cost to the students. Even though programming courses are typically free, the company just released a "Pro Suite" that will allow coders more advanced access to offerings. Early testing of the new suite has already attracted 20,000 users and $6 million in revenue.
