A search for a Keller LLC finance lawsuit can land on several different matters, because “Keller” appears in the names of multiple prominent law firms and in at least one unrelated contract case. The three firms most likely to be behind a finance-related result are Keller Postman LLC (formerly Keller Lenkner LLC), a Chicago plaintiffs’ firm known for mass arbitration and a current campaign against Google over ad pricing; Keller Rohrback LLP, a Seattle firm with a long financial-products docket including the Wells Fargo fake-accounts settlement; and Labaton Keller Sucharow LLP, a New York securities class action firm. A separate Missouri case, Intrua Financial Holdings v. Keller, involves an individual defendant named Andrew Keller rather than a law firm.
Keller Postman LLC
Keller Postman is the successor name to Keller Lenkner LLC, founded in Chicago in 2018 by Ashley Keller and Travis Lenkner. When Lenkner left in April 2022, former U.S. Chamber of Commerce chief appellate counsel Warren Postman became a name partner and the firm rebranded.1Law.com / The American Lawyer.

The firm works exclusively on alternative fee arrangements, focused on mass torts and mass arbitration. As of 2026, it reports $3 billion in total recoveries for more than 1.5 million clients.4Keller Postman. Keller Postman Homepage
The Mass Arbitration Model
Keller Lenkner’s signature strategy, launched in 2018, was to file thousands of individual arbitration demands at once against a single company. Because arbitration clauses obligate the company to pay steep upfront filing fees per claim, the aggregate bill creates settlement pressure before any case is heard on the merits.
Early targets were gig-economy employers. The firm filed 12,501 arbitration demands against Uber over driver misclassification, more than 10,000 against Postmates on wage-and-hour claims, and over 6,000 against DoorDash — 2,250 of them in a single day in May 2019. DoorDash’s initial arbitration-fee bill alone came to $9 million. When DoorDash tried to redirect the workers into a class action, a federal judge in the Northern District of California rejected the switch, noting the “poetic justice” of holding the company to its own arbitration terms.5Yale Law Journal. Mass Arbitration
The firm’s Amazon Alexa campaign filed roughly 75,000 arbitration claims over 16 months alleging the devices recorded users without consent. By May 2021, Amazon had dropped its mandatory arbitration clause entirely, restoring court access for over 140 million consumers.6Keller Postman.

The $1.4 Billion Meta Settlement and Other Class Results
Keller Postman’s largest single recovery is a $1.4 billion settlement with Meta Platforms on behalf of the State of Texas, announced in July 2024. The suit alleged violations of the Texas Capture or Use of Biometric Identifier Act and the Texas Deceptive Trade Practices Act, and the firm described it as the largest privacy-related settlement by a single state.8PR Newswire.

The firm also served as class counsel in a $17.45 million settlement with TaxAct over unauthorized data sharing. A federal judge in the Northern District of California granted final approval in December 2024, but a notice of appeal filed in January 2025 remains pending in the Ninth Circuit, so class members have not yet been paid.9ClaimDepot.

Google Ads Mass Arbitration
Keller Postman’s highest-profile active finance-adjacent matter, as of mid-2026, is a mass arbitration against Google on behalf of U.S. businesses that bought search and display advertising. The claims lean on two 2024 federal antitrust rulings and an April 2025 ruling by Judge Leonie Brinkema in the Eastern District of Virginia finding that Google “willfully acquired and maintained monopoly power” in publisher ad servers and ad exchanges.10Keller Postman. Google Ads Overcharges
Because Google’s ad contracts require arbitration instead of class actions, the firm is again using the mass-arbitration route. An economist retained by Keller Postman estimated potential total claims across search and display ads at $218 billion or more, though individual recoveries depend on each business’s ad spend. Google spokesperson Christa Muldoon called the claims “unfounded” and said the company would defend itself vigorously.11The Indiana Lawyer.

Keller Rohrback LLP
Keller Rohrback LLP is a different firm, based in Seattle, and it is the one most closely tied to traditional financial-products litigation. Its practice covers mortgage-backed securities, securities lending, interest rate manipulation, foreign currency trading, and credit default swaps.12Keller Rohrback LLP. Financial Products and Services The firm reports judgments and settlements exceeding $18 billion across all practice areas.
Its most widely covered case is the Wells Fargo fake-accounts litigation. Keller Rohrback filed the first class action in 2015 over the bank’s practice of opening unauthorized customer accounts. An initial $110 million settlement grew to $142 million after the class period was extended back to 2002. By January 2018, over 165,000 claims had been submitted, and the settlement required Wells Fargo to contact credit reporting agencies to suppress derogatory marks tied to the unauthorized accounts.13Courthouse News Service.

The firm has also represented the Federal Home Loan Banks of Boston, Chicago, and Indianapolis in private-label mortgage-backed securities litigation covering more than 200 securities with an original face value of $13 billion, against over 120 defendants.14Keller Rohrback LLP.
