Harvey hits $15.5B valuation, months after reaching $11B

Harvey secured $550 million at a $15.5 billion valuation, raising total funding to $1.55 billion. The round was co-led by Diffusion and Lightspeed Venture Partners. Earlier $200 million rounds increased the valuation from $8 billion to $11 billion. The funding follows the launch of Harvey Tenet, an in-house model based on Kimi K3 fine-tuned on legal data with Fireworks. Harvey now encourages customers to post-train their own open-weight models.
