Harvey raises $550M at $15.5B valuation, tripling worth in nine months

Legal AI startup Harvey has closed a $550 million funding round valuing it at $15.5 billion, co-led by Diffusion and Lightspeed Venture Partners. The raise comes just months after an $11 billion valuation in March and an $8 billion mark last December, bringing Harvey's total funding past $1.55 billion. The deal follows the company's launch of its own in-house model, Harvey Tenet, built on an open-weight foundation with help from Fireworks.
