Harvey's $11B Bet: Can Law Survive Without Billable Hours?

Opening

Dear reader, there’s a startup that began in a San Francisco apartment in 2022. A former lawyer and a former DeepMind researcher built a GPT-3 prototype for landlord-tenant dispute legal advice, then sent a cold email to Sam Altman. Three and a half years later, this company is valued at $11 billion (~₩16 trillion).

This is the story of Harvey, the legal AI startup. It recently raised $200 million in a round co-led by GIC and Sequoia Capital, crossing into decacorn territory (private companies valued at $10 billion or more). Total funding raised has now surpassed $1 billion.

But what I’m focused on isn’t these numbers. It’s not Harvey’s growth speed itself, but the structural conditions in the industry that made this growth possible.

🚀 Decacorn in Three Years: Harvey’s Trajectory

Looking at Harvey’s valuation changes chronologically, what’s striking isn’t just growth — it’s the acceleration itself.

• December 2023: Series B, valued at $715 million
• July 2024: Series C, $1.5 billion
• February 2025: Series D, $3 billion
• June 2025: Series E, $5 billion
• December 2025: Series F, $8 billion
• March 2026: Series G, $11 billion

In just over two years, the valuation jumped 15x. Annual recurring revenue (ARR) tells the same story. From $10 million at the end of 2023, to $50 million at the end of 2024, crossing $100 million in August 2025, and reaching $190 million as of January 2026. Revenue nearly quadrupled in a year and a half.

The customer roster is equally impressive. More than half of the AmLaw 100 (America’s top 100 law firms), over 500 in-house legal teams, and 50 asset managers across 60 countries are using Harvey. More than 100,000 lawyers across 1,300 organizations now work on the platform. Names like HSBC, NBCUniversal, and DLA Piper have recently joined the customer list. Sequoia Capital partner Pat Grady’s assessment of Harvey: in the AI transition, Harvey is playing the role Salesforce played during the cloud transition. The fact that Sequoia has led Harvey’s rounds three times is, in VC terms, a fairly strong statement of conviction.
