Harvey, the legal AI startup, announced Wednesday it has raised another $550 million in funding, pushing its valuation to $15.5 billion. This round was co-led by Diffusion and Lightspeed Venture Partners.
This latest capital follows a $200 million round announced in March, which valued the company at $11 billion. Before that, a December round saw an $8 billion valuation. With this new money, Harvey has now raised more than $1.55 billion in total and has nearly doubled its valuation in about nine months.
What is Driving Harvey’s Rapid Growth and Valuation?
The company, similar to Databricks, did not name this latest funding round. PitchBook estimates Harvey has completed at least eight priced rounds since 2023, with five of those occurring since 2025. This latest one could be considered a Series F.
The new funds arrive a couple of weeks after Harvey revealed its first in-house model, Harvey Tenet. This model was built from the open-weight Kimi K3 model and then refined with legal data, with assistance from inference provider Fireworks. Harvey not only offers its own model but also promotes its customers to use and further train their own open-weight models. This approach positions Harvey as a company showing how an entire sector, like law, can use AI extensively without relying on proprietary frontier AI labs such as OpenAI and Anthropic.
