In 2012, about 7 percent of all people aged 16 or older in the U.S. experienced identity theft, with their financial losses totaling $24.7 billion. Christopher Morton is familiar with the crime because in 2007, he had his identity stolen. Fortunately, the thieves were prevented from obtaining new credit cards, but Morton became interested in how identity verification systems work.

With co-founders John Backus and Alain Meier, Morton created BlockScore, an identity-verification startup and member of Y Combinator’s latest batch that is launching today with $2 million in funding from Battery Ventures, Khosla Ventures, Lightspeed Venture Partners, New Atlantic Ventures, Boost VC, Y Combinator, and several angels.
