What Keller Postman does
Keller Postman LLC is a national plaintiff-side law firm founded in 2018 and headquartered in Chicago, with additional offices in Washington D.C., Coral Gables, Lake Mary, and Boston. The firm represents consumers, veterans, employees, and businesses harmed by large corporations and the federal government across more than 25 active litigation practice areas, including NEC/infant-formula claims against Abbott and Mead Johnson, Camp Lejeune water contamination, Depo-Provera, acetaminophen/Tylenol, 3M Combat Arms Earplugs, Google Ads antitrust, Roundup, hair relaxer, social media addiction, BIPA, data breach, and state-level actions on behalf of Texas. It operates on a contingency fee basis (no win, no fee) and has reported more than $3 billion in cumulative client recoveries and 1.5 million clients represented, including landmark outcomes such as a $1.4 billion Texas settlement, a $70 million Abbott NEC verdict (2026), and a $60 million Mead Johnson NEC verdict (2024).
The firm's core operating model combines a senior talent bench (co-founders Ashley Keller and Warren Postman hold Harvard credentials and U.S. Supreme Court clerkships) with a dedicated in-house Technology, Data & Analytics team (35+ staff) and 80+ case managers that enable high-volume, standardized client intake and case management. Court-appointed leadership positions in major MDLs (Camp Lejeune, Tylenol, 3M Earplugs, Social Media Addiction) function as a quasi-distribution channel that directs case inventory to the firm. The go-to-market motion is sales-led and multi-channel: free case evaluation webforms, attorney referrals, co-counsel relationships, PR-driven earned media, and case-specific landing pages (e.g., adsrefund.com, nec-lawsuit.com) feed a continuous intake funnel across case types.
Keller Postman monetizes exclusively through contingency fees and court-awarded common-fund fees on settlements and verdicts, so revenue realization is back-end-weighted and lumpy, dependent on MDL scheduling and trial outcomes. The firm has no disclosed external funding, no parent company, and no public listing; ownership rests with founding and equity partners. As of the latest data, the firm employs approximately 300+ staff, including 70+ attorneys, and continues to expand its practice areas, geographic footprint, and operational leadership team.
