What Wilson Sonsini Goodrich & Rosati does

Wilson Sonsini Goodrich & Rosati is a full-service law firm founded in 1961 and headquartered in Palo Alto, California, providing legal services to technology, life sciences, and growth enterprises worldwide. The firm operates across five core practice areas—Corporate, Intellectual Property, Litigation, Patents and Innovations, and Regulatory—with sub-practices spanning venture financing, M&A, capital markets, securities litigation, FDA regulatory, antitrust, data privacy, and technology transactions. It maintains 17 offices in the United States, Europe, and Asia and is structured as a private partnership.

The firm monetizes through professional services billing—predominantly billable hour arrangements typical of AmLaw 100 firms, with selective use of alternative fee arrangements—delivered via direct client engagement rather than channel partners. It leverages the proprietary Neuron client platform for service delivery and has integrated Harvey AI for contract review and document automation, reporting 10-40% increases in matter capacity per attorney. It serves approximately 300 public companies and 3,000 private companies, with deep concentration in technology and life sciences verticals and active expansion into AI infrastructure, energy and climate solutions, and cross-border Asian markets.

Wilson Sonsini reported $1.4 billion in revenue in 2025, up from $549 million in 2012 under Managing Partner Doug Clark, who will be succeeded by Caz Hashemi and Megan Baier in August 2026. In 2025 alone, the firm advised on more than 150 M&A deals with aggregate disclosed value of $100 billion, was ranked No. 1 globally for company-side venture financing rounds per LSEG, and handled 770+ U.S. and 2,400+ foreign patent issuances on behalf of clients, underscoring its scale and dominance in technology and life sciences advisory work.
