TLDR: Duolingo’s shift to an ‘AI-first’ model, which included phasing out contractors and integrating AI into content creation and hiring, initially sparked significant consumer backlash, particularly in the US. Critics raised concerns about authenticity and a perceived betrayal of the brand’s human-centric image. However, despite the initial negative sentiment, Duolingo reported strong Q2 2025 earnings, with revenue up 41% and net income up 84%, indicating that the AI-driven strategy is proving profitable and driving user growth. The company’s stock soared, and it continues to see increased paid subscribers and daily active users.
Duolingo, the popular language-learning platform, has been at the center of a significant consumer debate following its CEO’s announcement of an ‘AI-first’ operational model. This strategic pivot, which involved reducing reliance on human contractors in favor of generative AI for content development and integrating AI into hiring processes, initially triggered a wave of criticism and user backlash, particularly within the United States.
The core of the controversy stemmed from a perceived shift in Duolingo’s brand identity. For many loyal users, Duolingo had cultivated a quirky, human-centric, and engaging online persona, often characterized by its playful green owl mascot and interactive social media presence. The move to an ‘AI-first’ approach was seen by some as a cold, calculated decision that prioritized algorithms over people, leading to concerns about the authenticity of the language learning experience and a sense of betrayal among its long-time fanbase. Reports emerged of users ending their streaks and even deleting the app, with snarky remarks appearing on Duolingo’s social media platforms. Morgan Stanley noted a 10% decline in domestic daily active users (DAUs) since April, directly attributing it to the ‘AI-First’ memo and user pushback.
However, despite this initial negative sentiment, Duolingo’s financial performance tells a different story. The company reported impressive results for the second quarter of 2025, with revenue increasing by 41% year-over-year to over $252.3 million. Net income saw an even more significant jump, rising by 84% to $44.8 million. This strong performance led to a substantial increase in Duolingo’s stock price, which soared by more than 24% after hours, reaching $426.60 per share from less than $344.
Duolingo’s co-founder and CEO, Luis von Ahn, expressed satisfaction with the results, stating in a letter to shareholders, ‘I’m happy to report another quarter of great results, driven by product-led growth, a delightful learning experience, and fast iteration.’ He emphasized that user growth and engagement remain strong, and subscription performance and profitability exceeded expectations. The company’s number of paid subscribers reached 10.9 million, up from 8 million a year ago, while daily active users neared 48 million, an increase from 34 million last year. Von Ahn believes that AI is actively contributing to boosting user engagement and profitability, indicating that the controversial strategy is, for now, paying off.
The company’s ‘AI-first’ approach means that artificial intelligence is the central driving force behind its business decisions, operations, and product development. While this promises increased efficiency and a streamlined user experience, it also sparked the initial backlash. Duolingo had reportedly cut approximately 10% of its contractors in late 2023 to make way for AI-related changes in content generation. However, von Ahn has clarified that employees, not AI, are the reason for Duolingo’s success and that the company plans to retain its current staff and continue hiring.
The company has also been aggressively promoting its top-tier Max subscription plan, which leverages AI tools for personalized role-playing sessions and explanations of mistakes. While some users have voiced complaints about this ‘pushy paywall,’ Duolingo maintains that its decisions are guided by constant user testing and data. Subscriptions now account for 85% of the company’s revenue, with growth driven by higher-priced plans like Duolingo Max.
