Wolf Popper

What Wolf Popper does

Wolf Popper LLP is a privately held New York-based litigation law firm founded in 1945 by Benedict Wolf and Martin Popper, structured as a limited liability partnership and led by Managing Partner Emily Madoff. The firm represents institutional investors, consumers, and businesses in complex matters spanning securities litigation, consumer fraud class actions, corporate transactional and derivative litigation, commercial litigation and arbitration, health care litigation, cryptocurrency/NFT/digital assets litigation, environmental litigation, international litigation and arbitration, whistleblower/False Claims Act litigation, and a Latin American practice. Wolf Popper pioneered securities litigation work beginning in 1957 with the landmark case Bauer v. Servel, Inc., and has been consistently ranked among the Top 50 North American plaintiff law firms for securities-related class action settlements by ISS's Securities Class Action Services (SCAS).

The firm delivers services through a network of offices in New York (headquarters), San Francisco, McLean (DC metro), Newton (Boston), Houston, Chicago, Springfield, Larchmont, and San Juan, Puerto Rico, with no proprietary technology product or platform. Revenue is generated through three professional-services streams: traditional hourly billing for complex litigation, contingency fee representation for class action and consumer fraud matters, and alternative fee arrangements that allow flexible billing structures for appropriate matters. The firm's Portfolio Monitoring Services product for institutional investors functions as a recurring case-origination pipeline and a differentiating capability versus peer plaintiff shops.

Wolf Popper's GTM motion is sales-led and reputation-driven: clients are acquired through industry recognition, judicial commendation, referral networks, and the firm's own investigations into potential class actions. The firm markets itself through its website, professional publications, earned media, social channels (LinkedIn, X/Twitter, Facebook), and newsletter subscriptions, and is currently expanding its California practice. As a private partnership with no disclosed funding rounds, no parent company, and no equity-backed structure, growth is funded organically from partner capital and case recoveries.
