Legal AI startup Harvey announced it has raised an additional $550 million in funding. This latest investment round was co-led by Diffusion and Lightspeed Venture Partners. This brings the company's valuation to $15.5 billion.
This funding follows a $200 million round in March at an $11 billion valuation, and an $8 billion valuation from a December round. Harvey has nearly doubled its valuation in approximately nine months, accumulating over $1.55 billion in total funding across at least eight priced rounds since 2023.
The new capital comes shortly after Harvey introduced its first in-house model, Harvey Tenet. This model was built from the open-weight model Kimi K3 and post-trained with legal data, with assistance from inference provider Fireworks.
Harvey encourages its customers to adopt and post-train their own open-weight models. This approach positions Harvey as an example of how the legal industry can utilize AI without exclusive reliance on proprietary frontier AI labs like OpenAI and Anthropic.
