Duolingo’s $1B AI-Driven Pivot Sparks Growth Despite User Backlash
In April 2025, Duolingo, the popular language-learning app, announced a bold shift to an “AI-first” strategy, sparking both controversy and a remarkable financial surge.
CEO Luis von Ahn revealed plans to prioritize artificial intelligence over human contractors, using AI to shape hiring, performance reviews, and content creation.
This move enabled Duolingo to launch 148 new language courses in under a year—a process that previously took over a decade—expanding access to languages like Spanish, Japanese, and Navajo.
However, the announcement triggered a swift backlash from users who felt the app’s human-crafted charm was at risk. Long-time learners deleted years-long streaks, and social media platforms buzzed with criticism, with some calling the shift “tone-deaf” and others fearing a loss of cultural nuance in lessons.
Despite the user revolt, Duolingo’s financial performance soared. In Q2 2025, the company reported a 41% revenue increase to $252.3 million, driven by 10.9 million paid subscribers and 48 million daily active users. Investors, undeterred by the controversy, pushed the company’s market value up by nearly $1 billion, with shares jumping nearly 30% after the earnings report.
Duolingo also raised its 2025 revenue forecast to over $1 billion, signaling confidence in its AI-driven growth. The company’s ability to convert free users to paid subscribers and boost engagement through AI features, like personalized learning and video-call practice, outweighed concerns about declining trust among some users.
The significance of this shift lies in its demonstration of AI’s potential to scale educational platforms rapidly while highlighting the risks of alienating users.
Research, including a 2025 NIH-funded review, suggests AI can enhance content delivery but may not consistently improve long-term learning outcomes without human oversight.
For users, the expanded course offerings mean greater access, but there’s a risk of shallow or inaccurate lessons, especially in less-common languages. For businesses, Duolingo’s success underscores the importance of balancing innovation with transparent communication to maintain user trust.
The company’s journey reflects a broader tension in edtech: prioritizing efficiency and scale can drive profits but may challenge the human connection that defines a brand’s identity.
