What Tycko & Zavareei does

Tycko & Zavareei LLP is a privately held plaintiffs-side law firm founded in 2002 by Jonathan Tycko and Hassan Zavareei, both former associates at Gibson, Dunn & Crutcher LLP. Headquartered in Washington, D.C. with offices in Oakland, Los Angeles, San Diego, and Cleveland, the firm concentrates on complex litigation on behalf of consumers, workers, and whistleblowers, including class actions, qui tam False Claims Act cases, commercial disputes, and appellate advocacy before state courts, federal circuits, and the U.S. Supreme Court. The firm has recovered more than $800 million for clients across matters involving financial services (Bank of America overdraft litigation yielding $1.2 billion in injunctive relief and $66.6 million in cash and debt relief; Citizens Financial Group $137.5 million settlement), consumer products (Sharp microwave litigation, $109 million), technology (Uber spam texts, $20 million; Apple Powerbeats, $9.75 million), insurance (Allstate, $25 million), and government contracting fraud (Advanced Biohealing whistleblower case, $350 million; Booz Allen Hamilton, $377 million).

The firm operates almost exclusively on a contingency fee basis, deriving revenue from a percentage of settlements and judgments in class actions and from the relator's share in qui tam recoveries. Client acquisition is driven by a combination of direct engagement, referrals from nonprofit partners including Public Justice and the National Consumer Law Center, and a dedicated whistleblower intake channel called Fraud Fighters (fraudfighters.net). The firm also runs a two-year Public Interest Fellowship Program, launched in 2012, that recruits recent graduates from Harvard, Northwestern, UNC, and American University law schools. The practice is run by Managing Partner Andrea R. Gold alongside co-founders Zavareei and Tycko, with a partner group that is 75% women and an attorney roster that is 50% women, and the firm has received industry recognition including Chambers USA rankings (2022-2025) and Lawdragon 500 Leading Plaintiff Consumer Lawyers (2025, 2026).

There is no technology platform or proprietary AI/ML product; the firm's output is human legal representation delivered across multiple specialized practice areas including Financial Services & Economic Justice, False Advertising, Privacy and Data Breach, Product Defects, Overtime/Wage and Hour, Employment Litigation, Defamation and First Amendment, and Government Contracts. Distribution is via direct client engagement and referral partnerships, and the firm's sub-brand Fraud Fighters extends acquisition reach into the whistleblower segment.
