The Globe and Mail reports in its Thursday edition that Ontario Teachers' Pension Plan has placed a bet in the crowded fast-growing artificial-intelligence-powered legal software space, investing $50-million in Harvey AI Corp., one of the leading platforms selling smart digital tools to lawyers (all figures U.S.). The Globe's Sean Silcoff and Joe Castaldo write that the investment by Teachers' Venture Growth is an extension of a financing the San Francisco company announced earlier this month. At the time, Harvey had raised $550-million at a valuation of $15.5-billion (U.S.). Harvey is one of the largest AI-powered software vendors globally, recently topping $400-million in annualized revenues just four years after it was co-founded by chief executive officer Winston Weinberg, a 31-year-old securities and antitrust litigator. The 1,400-person company serves 20 per cent of the Fortune 500 and has more than 3,000 customers in 70 countries. Its 100-plus customers in Canada include law firms Davies Ward Phillips, Dentons and Gowling. With the large language model giants and a surfeit of other players competing in the legal AI technology space, including Thomson Reuters, it's too early to know how the market will shake out.
