Jonathan Direnfeld


Washington, D.C. Office

Jon Direnfeld defends technology and data-driven companies against regulatory enforcement and litigation actions involving critical online and offline data management, and advertising, sales and marketing activities.

Jon’s enforcement work involves helping clients navigate the patchwork of federal and state “consumer protection” rules and defending investigations and enforcement actions brought by the Federal Trade Commission (FTC), U.S. Department of Justice (DOJ), State Attorneys General (AGs), and local District Attorneys. These matters cover a broad spectrum of B2C and B2B issues, including data privacy, cybersecurity, and so-called “unfair and deceptive” sales and marketing practices with a focus on representation of e-commerce platforms, marketplaces, gig economy, social media and fintech companies.  In connection with these enforcement matters, Jon is able to leverage his substantial experience in crisis management by helping clients devise and implement coordinated regulatory, legislative, and media responses to these high stakes incidents. 

Jon also has substantial experience in the antitrust and competition space, including class action antitrust litigation, criminal cartel investigations and enforcement actions before the DOJ and international regulators, as well as mergers and acquisitions and conduct investigations before the DOJ and FTC. In addition, Jon also provides strategic public policy counseling to clients on consumer protection and data management matters before Congress and executive branch agencies, and he has an active complex commercial litigation practice in federal and state courts across the country.
