Data analytics firm IHS Inc. said Monday it has acquired Carproof Corp., a Canada-based provider of used vehicle data, for C$650 million (approximately $460 million). The deal closed over the last couple of days, according to a source familiar with the situation. London, Ontario-headquartered Carproof, founded in 2000, provides automotive vehicle history reports to dealers, auto auctions, original equipment manufacturers, lenders, insurers, governments, law enforcement agencies and consumers. The company has more than 130 employees. San Francisco private equity firm Hellman & Friedman LLC purchased a minority stake in Carproof in August 2013 for an undisclosed sum.
