What Korein Tillery does
Korein Tillery is a plaintiffs' complex-litigation boutique law firm headquartered in St. Louis, Missouri, with additional offices in Chicago, Naples, and San Diego. The firm concentrates on high-stakes, resource-intensive litigation across six core practice areas: antitrust, securities, ERISA, commercial, whistleblower, and environmental litigation. Its client base spans federal and state governmental entities (notably the National Credit Union Administration and over 400 Missouri municipalities), certified plaintiff classes (including 13 million California Android users and minor league baseball players), pension plans and their participants, and financial institutions.
The firm operates on a contingency fee model, investing its own capital in cases and receiving payment only upon successful recovery, which aligns firm economics with client outcomes and removes upfront cost barriers for plaintiffs. Go-to-market is sales-led and relationship-driven: Korein Tillery receives hundreds of referrals annually and routinely co-counsels with leading plaintiffs' boutiques and major international corporate firms, including partnerships with Pearson Simon & Warshaw, Bartlit Beck, McManis Faulkner, and Hilgers Graben. The firm has recovered over $17 billion in verdicts and settlements over two decades, with landmark outcomes including $5.2 billion for NCUA against Wall Street banks in RMBS litigation, $185 million for minor league baseball players, and a $350 million settlement following a $314 million jury verdict in Csupo v. Google.
On the technology layer, Korein Tillery adopted RelativityOne in October 2024, an AI-powered cloud e-discovery platform used to manage complex litigation data and accelerate document review. This represents a third-party AI tooling investment rather than proprietary technology development. The firm is led by senior member Stephen Tillery and managing partner Christine Moody, with a partner roster drawn from top-tier law schools and federal clerkships and prosecution backgrounds.
