What Keller Lenkner does
Keller Lenkner, operating publicly as Keller Postman LLC, is a plaintiff-side litigation firm founded in 2018 and headquartered in Chicago, Illinois. The firm represents individuals and businesses in mass tort, class action, and mass arbitration matters, with active practice areas spanning NEC/infant formula litigation, Camp Lejeune water contamination claims, pharmaceutical injury cases (Depo-Provera, acetaminophen/Tylenol, Zantac, Paragard), product liability (3M Combat Arms earplugs, hair relaxer), Roundup, and emerging social media addiction litigation. The firm claims to have represented 1.5 million clients and secured $3 billion in verdicts and settlements. Leadership includes Senior Partner Ashley Keller and Director of Strategy Nicholas Cooper.
The firm's go-to-market is direct-to-consumer: clients are acquired through the corporate website, a national phone intake line, and dedicated case-specific landing pages (nec-lawsuit.com, birthcontrol-injury.com, adsrefund.com), with marketing emphasizing free case evaluation and a no-recovery, no-fee contingency model. The firm operates four offices across Chicago, Washington D.C., and two Florida locations (Coral Gables and Lake Mary) and employs 300+ attorneys and staff, including case managers and technology personnel. Revenue is generated exclusively through contingency fees as a percentage of client recoveries, which creates a high-variance, outcome-linked revenue stream rather than recurring contracted revenue.
The firm has no proprietary technology platform disclosed, no AI/ML capability surfaced in public materials, and no external funding, parent company, or M&A activity reported. Its distribution moat rests on branded acquisition websites, earned media presence across major outlets, and a recognized brand reinforced by 2024 industry awards (Best Lawyers, U.S. News Best Law Firms, Elite Trial Lawyers, Legal 500, Super Lawyers, BBB accreditation). The business model is fundamentally a packaged-claims operation: aggregate large plaintiff pools, fund litigation against well-capitalized defendants, and monetize through percentage-of-recovery fees.
