About O'Sullivan Michael J.

Michael O’Sullivan serves as General Counsel of Snap Inc., the U.S.-listed parent company of Snapchat. Snap’s official leadership materials state that he has held this role since July 2017. His career path is rooted in corporate law, governance, and high-stakes advisory work for technology and growth companies. Before joining Snap, O’Sullivan spent many years in private practice, including a long tenure at Munger, Tolles & Olson LLP in Los Angeles, where he focused on corporate transactions, governance matters, and significant disputes. In that setting, he advised companies, boards of directors, and founders on issues that often required both legal precision and business judgment. That background is especially relevant in a company such as Snap, where executive legal leadership must support innovation while navigating regulatory scrutiny, intellectual property issues, commercial risk, and corporate governance demands. O’Sullivan’s role is therefore central to the company’s executive framework, even if the public record is more detailed on his legal advisory background than on individual deal-by-deal decisions. He holds a J.D. from the University of Southern California’s Gould School of Law and a B.A. from the University of Pennsylvania. Overall, his profile reflects a seasoned in-house legal leader with deep experience in corporate counsel work, board-level advising, and the management of complex legal and governance matters for a publicly traded technology company.
