Luis von Ahn

Luis von Ahn founded Duolingo in 2011 with the revolutionary vision of solving two massive global problems simultaneously: the lack of accessible language education and the need to translate the internet. His background in computer science and human computation, pioneered through the creation of reCAPTCHA, led him to design a platform that gamified the translation process, turning education into a crowdsourced utility before pivoting entirely to pure education when neural machine translation rendered the original model obsolete.

Luis von Ahn, born in 1978 in Guatemala City, Guatemala, is a Guatemalan-born entrepreneur and computer science professor at Carnegie Mellon University (CMU) who is widely recognized as a pioneer in the field of 'human computation' and 'CAPTCHA' technology. Before founding Duolingo, von Ahn invented the original CAPTCHA system while a PhD student at Carnegie Mellon, and later founded reCAPTCHA, which was acquired by Google in 2009 and used to digitize millions of books and newspapers. Von Ahn's academic research focused on how human brains could be leveraged to solve problems that computers could not, a concept that became the foundation for Duolingo's original business model. Under his leadership as CEO, Duolingo has grown from a small startup in Pittsburgh to the most downloaded education app in the world, with over 116 million monthly active users and a valuation of over $13 billion. Von Ahn is a strong advocate for free education and has consistently maintained that Duolingo's core mission is to develop the best education in the world and make it universally available. He is known for his data-driven approach to product development, his focus on gamification and behavioral psychology, and his commitment to maintaining a strong, unique corporate culture in Pittsburgh rather than relocating to Silicon Valley. Von Ahn holds a PhD in Computer Science from Carnegie Mellon University and a Bachelor's degree in Mathematics from Duke University.
