- Duolingo, Inc. is a leading mobile learning platform that offers free language education and has become the world's most popular way to learn languages, surpassing 50 million daily active users and generating over $1 billion in bookings for the first time in 2025.
- In February 2026, Duolingo announced a $400 million share repurchase program and outlined a strategic focus on user growth and enhancing the free learner experience, despite a projected slowdown in bookings growth to 10-12% for 2026.
- The company has a diverse user base, including individuals and educational institutions, and is expanding its offerings to include learning in chess, math, and music, aiming to reach 100 million daily active users in the medium term.
- Duolingo's ideal buyers are educational institutions and individual learners seeking effective, engaging, and accessible language learning solutions, particularly in light of increasing competition from AI-powered educational tools.
Engineering is Duolingo’s largest department at 347 employees, accounting for just over 40 % of total headcount and underscoring the product-centric nature of the business. Marketing and Product follows with 198 employees, reflecting the need to promote the brand and continuously refine the learning experience. Business Management, Human Resources, Operations, IT, Finance & Administration, Sales & Support, and Quality collectively comprise the remaining workforce, each ranging between two and eight percent of overall staff. Company-wide hiring outpaced attrition, resulting in a modest increase across most teams.
Duolingo’s headquarters in Pittsburgh houses the single largest concentration of employees at 289, while New York hosts 187 team members and serves as a key East Coast hub. Additional U.S. offices in Seattle, San Francisco, Los Angeles, Detroit, Boston, and Philadelphia contribute smaller but strategic groups that support engineering, design, and business operations. An international presence is anchored by a Berlin office, complemented by distributed talent classified under “Other,” which totals 279 employees and highlights the company’s flexibility toward remote and hybrid work arrangements.
