Tod Cohen is one of the technology industry’s foremost experts on Internet law and policy. He draws upon more than two decades of experience in-house with some of the world’s best-known internet and e-commerce companies to provide tech clients with practical, strategic advice on critical evolving issues in data privacy, payments, antitrust and competition law, and content moderation.

Prior to Twitter, Tod was General Counsel of StubHub, where he directed the company’s legal and policy team overseeing payments regulation, mergers and acquisitions, strategic partnerships, antitrust law, privacy and data protection, and global public policy. Before that, he served as Deputy General Counsel of eBay, responsible for global public policy for eBay, PayPal, Skype, eBay Classified Group, and StubHub as well as eBay’s Global Asset Protection Team and the company’s offensive and defensive antitrust work.
