AI law firm Crosby bids on Weil Gotshal assets
AI-first law firm Crosby has submitted a bid to acquire certain assets of the disintegrating Wall Street firm Weil, Gotshal & Manges, including its trademark, brand, and unspecified internal data. The startup is also seeking to hire some of Weil's 1,200 lawyers. Weil Gotshal confirmed it is preparing to vote on dissolution after its presumed leadership heir declined the role, top lawyers departed, and a merger with Willkie Farr & Gallagher fell through. Crosby, which raised about $85 million including a $60 million Series B in March led by Lux and Index, aims to revolutionize legal services with its proprietary AI, offering unprecedented speed. The terms of the bid are undisclosed, and there is no guarantee Crosby will prevail, but if successful, Weil Gotshal's legacy could be transformed under an AI-first model.
AWS Invests $1B in Forward-Deployed AI Engineering Unit
Amazon Web Services announced a new internal Forward-Deployed Engineering (FDE) organization backed by $1 billion of internal resources to embed AI-focused engineers inside customer companies. The team will deploy purpose-built, agentic systems in customers’ own AWS environments with an emphasis on short engagements and customer self-sufficiency, and AWS says clients will leave with lasting engineering capabilities. The move follows similar FDE initiatives launched recently by OpenAI and Anthropic (valued at $4 billion and $1.5 billion respectively) and follows a model pioneered by Palantir. The signal duplicates an earlier report that AWS planned to staff the unit at scale and work alongside customers and third-party FDE partners while competing with other model labs.
Anthropic and OpenAI Push Enterprise AI Services
Silicon Valley AI labs are moving aggressively into enterprise services and infrastructure. Anthropic announced a joint venture with Blackstone, Hellman & Friedman and Goldman Sachs backed by roughly $1.5B of funding, while OpenAI launched a private‑equity‑backed Deployment Company that has raised about $4B at a reported $10B pre‑money valuation. Concurrently, OpenAI rolled out GPT‑5.5 Instant (gpt-5.5-chat-latest) as ChatGPT’s default with stronger personalization and real‑time/voice infra updates, and Google released Gemma 4 multi‑token prediction (MTP) drafters promising multi× decoding speedups. The report also highlights large infra financings (RadixArk $100M seed for SGLang/Miles), growing enterprise vertical products (finance, medical), and technical themes around agent harnesses, coding benchmarks (ProgramBench), and inference economics.
