A tech startup backed by $133 million in funding from Silicon Valley venture capitalists, wants to reinvent the way children learn in the United States by personalizing education. The for-profit school system called "AltSchool" now operates eight small private schools in the San Francisco Bay Area and New York - with ambitious plans to eventually license its program to public schools across the country. AltSchool's co-founder founder, a former Google executive, believes the techniques learned in the tech industry, like collecting personal data on users, can help transform education.
