-Harvey AI, a fast-growing legal startup, is in advanced talks to raise over $250 million in a new round of funding at a valuation of $5 billion, sources familiar with the matter told Reuters.

The funding round, led by venture capital firms Kleiner Perkins and Coatue, would mark a significant leap in Harvey's valuation from $3 billion in just a few months. Sequoia Capital, an existing backer, is also expected to increase its investment in this round.
