Legal artificial intelligence (AI) startup Harvey is in talks to raise $500 million at a $15.5 billion valuation, including the investment, The Information reported Friday (Aug. 7), citing an unnamed source. The reported valuation would be up from the $11 billion valuation Harvey achieved in a March funding round in which it raised $200 million. Harvey’s annualized revenue has leapt more than 80% since January, from $190 million to more than $350 million, according to the report. Harvey announced July 28 that Growth Equity at Goldman Sachs Alternatives and J.P. Morgan Growth Equity Partners completed an investment in the company. Legora, a legal AI firm, announced in April that it secured a $50 million extension of its previously announced Series D financing.
