Warren Postman is a legal pioneer, using the strategy of “mass arbitrations” to help consumers assert their rights en masse. Warren met his co-founding partner Ashley Keller nearly 15 years ago while clerking for Justices David Souter and Anthony Kennedy, respectively. Over the past few years they have created new techniques in class action and arbitration to enforce rights for consumers who have signed contracts waiving rights to civil trials. Warren has turned the tables on companies that draft arbitration clauses in click-wrap and other asymmetrical contracts, bringing large-scale arbitrations more akin to a class-action lawsuit. His firm has won precedent-setting victories against Intuit, Postmates, and DoorDash, among others. In less than a year in practice, his firm has achieved settlements and litigation victories for more than 500,000 consumers, and his firm is currently pursuing high-stakes antitrust and consumer-rights cases against tech giants such as Google, Amazon, Facebook, and LinkedIn.
