Harvey sells to Big Law, hires 22 of its lawyers, signs Iberdrola for 300 seats
Of the 46 Am Law 200 lawyers who left for AI companies in the first half of 2026, Harvey hired 22, weeks after closing $550 million at $15.5 billion. The talent tracker behind the count asks the question the round now poses: whether law firms' software suppliers are becoming competitors for their people.

The associates walked out, and someone counted
Forty-six lawyers left Am Law 200 firms for AI companies in the United States in the first half of 2026, and 40 of them were associates 1. Fifteen took the "legal engineer" title, a job Harvey itself began certifying in August 1. The tally is Firm Prospects', published on 1 October by Non-Billable.
The mark that pays for the hiring
On 9 September Harvey raised $550 million at a $15.5 billion valuation, up from $8 billion in December 47. Teachers' Venture Growth, the Ontario pension's venture arm, added $50 million on 24 September, extending the round to $600 million 8. Retirement savings now carry a mark near 39 times Harvey's roughly $400 million of revenue, on 1,500 employees 3.

The supplier is also the recruiter
Firm Prospects chief executive Adam Braveman names the fight: whether law firms' technology suppliers are becoming competitors for their people 1. Harvey says it is used by 80% of the 100 highest-grossing US firms 6. It also hired 22 of the 46 1.

The billable hour pays for both sides of the trade
The model under pressure is the one doing the paying. Firms bill associate hours; Harvey sells software that does associate work, recruits the associates to build it, and increasingly stations paid legal engineers inside client firms 14. The buyers who benefit are in-house teams such as Iberdrola's, trading seats for partner time 2. The listed incumbent most exposed is Thomson Reuters, Reuters' parent, whose CoCounsel tied agentic workflows to its Westlaw library in August 46.
Around the firms, into the client
Iberdrola is extending Harvey across legal and tax teams in dozens of jurisdictions, more than 300 professionals, with implementation by ECIJA, the Spanish firm Harvey named its Latin America strategic partner in May 2. The Boston office announced on 1 October, with at least 40 hires, will serve in-house teams at DraftKings, athenahealth and Toast alongside law firm customers 3. From the buyers' side, ILTA's 2026 survey shows 41% of firms naming cost and ROI a top concern, the first time it made the list 4.
Small numbers, no track record
Against nearly 16,000 moves into and out of Am Law 200 firms in the period, 46 is a rounding error 1. Harvey says the round helps firms "build and own their intelligence at scale" 6. Whether the leavers stay in technology is untested; the role is too new 1. The data does not say whether the firms that lost lawyers are Harvey customers, only that most large firms are 16.
What to watch next
Legora lists nearly 50 open legal-engineering positions, enough to keep the drain running into 2027 1. OpenAI's Astra for Law arrived in September 1. CMS and Dentons sold their Noxtua stakes last week as rented platforms spread 5. The next reading is Firm Prospects' full-year count. The AI invoice and the associate resignation now come from the same address.
