Harvey, which builds generative AI tools for law firms, raised a $21M Series A led by Sequoia with participation from the OpenAI Startup Fund and others

Context & Ripple Effects
This $21M round is the opening move in one of legal tech's fastest value climbs on record. Within eight months, Harvey had converted the momentum into an $80M Series B co-led by Elad Gil and Kleiner Perkins at a $715M valuation, built on tools that run on OpenAI's technology — which explains the strategic logic of the OpenAI Startup Fund taking a seat at this table so early.
Sequoia's lead here proved to be a conviction position, not a one-off: the firm came back to lead Harvey's $300M Series D at a $3B valuation by early 2025, by which point CEO Winston Weinberg disclosed ARR above $50M. The intermediate stretch showed the volatility underneath — reported talks to raise $600M at $2B+ collapsed into a smaller ~$100M raise at a $1.5B valuation.
First-order effects
- Harvey gets runway to scale its law-firm deployments while staying tightly coupled to OpenAI's models, with the Startup Fund's check aligning supplier and customer-side interests.
- Sequoia locks in an early position at a modest entry price that subsequent rounds would reprice dramatically upward.
Second-order effects
- The rapid jump from $21M to a $715M valuation in under a year reset pricing expectations across vertical AI, feeding the inflated mid-2024 talk tracks around $600M raises that markets then corrected downward.
- Law-firm incumbents' existing research vendors face pressure as Harvey's funding enables bundling AI workflow tooling into the same budget lines.
Third-order effects
- If the pattern holds, application-layer AI companies built on third-party foundation models must graduate to owning proprietary assets — Harvey's later moves toward its own in-house legal model and a contemplated purchase of legal-research firm vLex point exactly there.
- Vertical AI consolidates around a few heavily capitalized winners per industry, with elite-tier VCs like Sequoia doubling down rather than diversifying across many bets.
The trend: Legal AI is following the arc from thin wrappers on OpenAI's models toward vertically integrated platforms with proprietary models and acquired data assets, financed by rapidly escalating venture rounds.
