AI Law Firm Crosby Bids to Acquire Assets of Weil Gotshal
Crosby has submitted a bid to acquire select assets of dissolving Weil Gotshal & Manges.
Why it matters: This acquisition could reshape legal market strategies by blending AI-driven service models with established BigLaw brands. Legal operations and in-house teams should watch how this may affect law firm capabilities, client service, and innovation adoption.
- Crosby, founded in 2025, integrates proprietary AI directly into its legal services, differing from typical AI vendors.
- Weil Gotshal & Manges, established in 1931 with about 1,200 lawyers, is dissolving after leadership turmoil and partner losses.
- Crosby raised roughly $85 million, including a $60 million Series B round in March 2026 led by Lux Capital and Index Ventures.
- Weil Gotshal fell from ninth in global deal advising rankings in 2022 to outside the top 25 by 2025, reflecting its decline.
Crosby, an AI-centric law firm launched in 2025, has officially bid to acquire key assets of Weil Gotshal & Manges as Weil prepares to dissolve following internal leadership challenges and partner departures (TechCrunch).
Weil Gotshal, a nearly century-old firm with about 1,200 lawyers, experienced a sharp market decline. Once ranked ninth globally for deal advising in 2022, the firm dropped below the top 25 by 2025 amid failed merger talks and strategic setbacks (Axios).
Unlike traditional tech vendors who sell AI tools to firms, Crosby embeds its proprietary AI directly into legal workflows, operating as a full-service firm. This positions AI as a fundamental service component rather than an add-on technology.
Crosby’s bid reportedly covers Weil Gotshal’s trademarks, brand, and internal data. Details on how Crosby plans to integrate Weil’s lawyers, practice groups, or client portfolios remain confidential. The outcome could affect lawyers’ careers and ongoing client matters.
This move underscores a shifting BigLaw business model: AI-native firms acquiring parts of legacy firms to combine recognized brands with innovative technology. For in-house and legal operations leaders, this could signal evolving options in law firm partnerships and service delivery models.
As AI firms like Crosby gain footholds through acquisitions, legal tech adoption could accelerate, changing how firms organize and deliver legal services.
By the numbers:
- 2025 — Year Crosby was founded
- $85M — Crosby’s total funding raised as of 2026, including $60M Series B
- 95 years — Weil Gotshal’s legacy before dissolution begins
Yes, but: While Crosby’s innovative model promises change, details on integration and client impact remain unclear, posing risks for affected lawyers and clients.
