Cleary Gottlieb Steen & Hamilton

What Cleary Gottlieb Steen & Hamilton does

Cleary Gottlieb Steen & Hamilton is a privately-held international law firm organized as a limited liability partnership (LLP), with its primary entity domiciled in New York and affiliated entities in the UK, Italy, Brazil, and Hong Kong. The firm was founded in 1946 and operates 14 offices across the Americas, Europe, Asia Pacific, and the Middle East, employing approximately 1,100 lawyers led by 240 partners and supported by 1,200 professional staff. Cleary generated over $1.7 billion in gross revenue (Business Insider via former managing partner Michael Gerstenzang) and advises large corporations, financial institutions (banks, private equity, asset managers) and sovereign governments on cross-border M&A, capital markets, competition, restructuring, and litigation matters. Notable mandates include Uzbekistan's $2.4 billion LSE IPO, Busy Ming's $470 million Hong Kong IPO as joint sponsor advisor, and Brazil sugar/ethanol producer Raizen on liquidity crisis work. Pricing is built on the billable-hour model standard to BigLaw (specific rates not publicly disclosed), with enterprise, partner-led engagement teams as the dominant GTM motion.

The firm's core technology assets sit inside subsidiary ClearyX, a wholly-owned alternative legal and business services arm offering the CX+ platform — comprising CX+Insights for contract portfolio management and CX+Transact for M&A due diligence — with model-agnostic architecture and native document-management integrations, documented across 150+ deals with claimed 40-60% time and cost savings. Internal AI capability was seeded by the 2023 acquisition of Springbok AI (10 data scientists and engineers), and the firm also licenses Harvey AI, has rolled out Swedish legal-AI vendor Legora firmwide, co-developed AI workflow tooling with Lighthouse Global for FTC HSR second-request handling, and implemented Litera Foundation's knowledge management platform across five practice areas since 2020. CX+ products are sold via subscription with flexible licensing to in-house legal teams, positioning ClearyX partly as a hedge against AI-driven billable-hour compression. The firm has recognized Responsible AI Principles aligned with GDPR and CCPA obligations, holds multiple Chambers and FT Innovative Lawyers recognitions, and is investing in client-facing AI ecosystems through its design-partner role in Legora Portal alongside eleven other major firms.
