- Harvey raised $550 million at a $15.5 billion valuation, co-led by Diffusion and Lightspeed Venture Partners and announced Wednesday
- Harvey's valuation climbed from $8 billion in December to $11 billion in March to $15.5 billion now, nearly doubling in about nine months
- Harvey has raised more than $1.55 billion total across at least eight priced rounds since 2023 (five since 2025), per Pitchbook; the unnamed round could be considered a Series F
- Harvey Tenet, the company's first in-house model, was built from open-weight model Kimi K3 and post-trained with legal data using inference provider Fireworks
- Harvey encourages customers to adopt and post-train their own open-weight models rather than relying on proprietary providers
- The company's strategy positions the legal industry as a sector that can use AI heavily without depending on frontier labs like OpenAI and Anthropic
Why it matters: Harvey's $15.5 billion valuation — nearly doubled in nine months — shows investors will fund a legal-AI stack deliberately built outside frontier model labs. By basing Tenet on open-weight Kimi K3 and pushing law firms to post-train their own models, Harvey is creating a vertical where OpenAI and Anthropic are not the default substrate.
