A class action lawsuit has been filed against Duolingo (NASDAQ: DUOL) on behalf of investors that bought its Class A common stock between May 2, 2025 and February 26, 2026, law firm Kaplan Fox & Kilsheimer LLP announced. The complaint alleges Duolingo made false and misleading statements that hid the harm that more ads, subscription upsells, and AI-generated content did to daily active user growth. The stock fell 25% on November 6, 2025, 8.5% on January 12, 2026, and 14% on February 27, 2026. Those drops followed weak results showing slower user growth and the departure of the company's chief financial officer. Investors who want to seek the lead plaintiff role must move the court by December 7, 2026.
Bronstein, Gewirtz & Grossman LLC urges Duolingo, Inc. investors to act: Class Action filed alleging investor harm. NEW YORK, Oct. 18, 2026 (GLOBE NEWSWIRE) - Bronstein, Gewirtz & Grossman, LLC, a nationally recognized investor-rights law firm, announces that a class action lawsuit has been filed against Duolingo, Inc. (NASDAQ: DUOL) and certain of its officers. "Our practice focuses on restoring investor capital and ensuring corporate accountability to uphold market integrity," said Peretz Bronstein. This lawsuit seeks to recover damages against Defendants for alleged violations of the federal securities laws on behalf of all persons and entities that purchased or otherwise acquired Duolingo securities between May 2, 2025 and February 26, 2026, both dates inclusive (the "Class Period"). Such investors are encouraged to join this case by visiting the firm's site: bgandg.com/cases/duolingo-inc-duol-class_action_lawsuit. Duolingo Case Details The Complaint alleges that throughout the Class Period, Defendants failed to disclose that: (1) Daily Active User ("DAU") growth rates were being leveraged against deliberately added user friction in the form of significant increases in ad volume, subscription tier upsells, and worsened product quality, and Duolingo understood that any amount of user friction would cause users to leave the app and, ultimately, negatively impact DAU growth rates; (2) the Company's rigorous A/B testing demonstrated that increased friction in the free user experience was having negative impacts on DAU growth rates; (3) Duolingo's quickly generated AI content was worsening the quality of the Company's product offerings, negatively impacting the user experience and user trends, and threatening the sustainability of the Company's financial performance; and (4) Duolingo's constant A/B testing informed the Company that its monetization push and lower-quality, rapidly generated AI content were degrading the Duolingo product experience and the value proposition of its subscription tiers.

If you suffered a loss in Duolingo you have until December 7, 2026, to request that the Court appoint you as lead plaintiff. Your ability to share in any recovery doesn't require that you serve as lead plaintiff. No Cost to Duolingo Investors We, Bronstein, Gewirtz & Grossman LLC, represent investors in class actions on a contingency fee basis.

Corner Table Creative introduces hospitality-inspired agency model and welcomes 3 hires. Corner Table Creative welcomes Jessica Killian, Marissa Osowsky and Alexa Baldacci Editorial Series People moves, company launches, account wins and other business news. Photo credit: Ripp Photography Co. Corner Table Creative has been rolling out a new agency model inspired by its hospitality ethos, formally structuring teams into front of house and back of house roles, alongside the hiring of three new directors to support the shift. The model mirrors how high-performing hospitality groups operate: front of house teams, made up of client experience and brand strategists, focusing on client relationships, strategic oversight, and experience design, while back of house teams, creatives, designers, creators and producers concentrate on execution, content creation, and production across organic and paid social. The approach is designed to maintain the hybridity the agency is known for while clarifying responsibilities to scale output without compromising creative quality or client service, a growing challenge for social-first agencies as demand for always-on content accelerates. The new hires include: * Jessica Killian, creative director (back-of-house) * Marissa Osowsky, client experience director (front-of-house) * Alexa Baldacci, client experience director (front-of house) Killian most recently joined from ChukMedia where she worked on over 20+ different brands including Palmer's Skincare, growing their TikTok from 0-380K, Bausch + Lomb portfolio brands, developing Lumify's first Super Bowl spot, Wet Brush and Olipop. Prior to that Jessica Killian was a senior art director at Vayner Media on Olay and Chase Sapphire. Osowski joins from TBWA/Chiat/Day where she was a business director on Goldman Sachs, Carnival and Henkel, prior to that she was at Arts & Letters Creative Co. working on Google. Baldacci joins Corner Table Creative from Duolingo and NBC/Peacock where she led performance marketing strategy. The agency partnered with New Best Friend Co. for recruitment. "This structure allows us to grow intentionally while protecting what matters most: strong client partnerships and really memorable creative," said Rachel Brandt, co-founder and CEO of Corner Table Creative. "By clearly defining how teams show up, and valuing both sides of the house equally, we're building a more sustainable and effective agency model." Madeline Meade, co-founder and CCO added, "We are thrilled to bring Jess, Marissa and Alexa in to help lead our teams at this time of pivotal growth and set the tone for our new model as we enter the next chapter of Corner Table Creative." The restructure and hires are also a result of recent rapid growth for the award-winning agency. With new clients that include Match, Starbucks and OXO, the agency has grown to a 43-person team, 30 client partners, and will exceed $12M in revenue this year.

Specifically, Defendants misrepresented and/or failed to disclose that: (1) daily active user ("DAU") growth rates were being leveraged against deliberately added user friction in the form of significant increases in ad volume, subscription tier upsells, and worsened product quality, and Duolingo understood that any amount of user friction would cause users to leave the app and, ultimately, negatively impact DAU growth rates; (2) Duolingo's rigorous A/B testing demonstrated to the company that increased friction in the free user experience, including its monetization push and rapidly generated low-quality AI content, was having negative impacts on DAU growth rates; (3) Duolingo's quickly generated AI content was worsening the quality of Duolingo's product offerings, negatively impacting the user experience and user trends, and threatening the sustainability of the company's financial performance; and (4) as a result of the foregoing, Defendants' statements about the company's business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times.
