An AI Legal Startup Just Bid for the Corpse of Weil Gotshal, the Two Billion Dollar Law Firm That Died in Weeks

The law firm best known for managing the collapse of Lehman Brothers has now become its own cautionary tale, and an artificial intelligence startup wants a piece of what is left behind. Crosby, a legal AI company less than two years old, has submitted a letter of intent to acquire portions of the assets of Weil, Gotshal and Manges, the New York firm that announced this week it would dissolve after 95 years in business, according to a report by The Information on October 29.

Weil was legal aristocracy. The firm generated more than $2 billion in annual revenue with profits per partner above $5 million, and its name was attached to some of the most consequential matters in corporate history: the Lehman Brothers bankruptcy in 2008, the Enron proceedings in the early 2000s, Microsoft's defense of its Activision Blizzard acquisition, and Apple's trade secret lawsuit against OpenAI. None of that financial strength could stop what happened next.

The end came with astonishing speed. In September, star M&A partner Michael Aiello led a team out the door to Cravath, Swaine and Moore, removing one of the firm's largest revenue streams. The departure triggered a chain reaction in which partners, worried about their own earnings from a shrinking profit pool, accepted offers from rival firms. The Australian Financial Review called it the biggest law firm failure in modern history. Weil has hired Davis Polk as an adviser on the wind-down, according to The Wall Street Journal.

What Crosby wants is telling. The letter of intent covers internal data, trademarks and the brand, rather than client relationships, which dissolve with the partners who hold them. For an AI company, the internal data is the real prize: years of accumulated M&A agreement templates and negotiation-stage contract playbooks, structured legal documents that are not specific to any client and can be used for fine-tuning legal models. Crosby also hopes to recruit lawyers from Weil's roughly 1,200-strong bench. Terms were not disclosed, and it is unclear whether other bidders will emerge.

Crosby itself is a product of the current funding cycle. Founded by a lawyer and a former engineering manager at payments startup Ramp, the company has raised more than $80 million from Lux Capital, Index Ventures, Sequoia Capital and Bain Capital Ventures, reaching a $400 million valuation. It keeps more than 50 practicing lawyers on staff to review AI-assisted output and supervise negotiations, with its agents running on models from OpenAI, Anthropic and Google.

The bid fits an emerging pattern in which AI companies treat the data of failed or struggling firms as an acquisition target. Google and AI training startups Mercor and Micro1 have reportedly bid for the internal data and software code of bankrupt budget airline Spirit Airlines, down to mundane items like emails and IT tickets. In each case the buyer is not purchasing a business so much as the raw material to train one.

The episode also underlines how fragile the law firm partnership remains in the age of mobile capital. Harvard law professor John Morley once wrote that law firms die with extreme ease and astonishing speed, and Weil proved the point within weeks of its first senior defection. The AI industry's lesson is different: when a century of institutional knowledge becomes training data, the buyers are already waiting.
