Duolingo, the language-learning company known for its gamified mobile app and English-proficiency tests, employs roughly 850 people worldwide. Headcount has expanded through 108 recent hires, while 59 departures have kept overall turnover modest and manageable. The figures suggest steady scaling of talent to support product development, content creation, and global market outreach.
Engineering is Duolingo’s largest team with about 342 employees, accounting for just over 40% of the workforce and underscoring the company’s technology-driven focus. Marketing and Product follows with 197 employees, reflecting the importance of user acquisition, brand partnerships, and feature design. Business Management (67) and Human Resources (57) provide core operational support, while several similarly sized groups—including Operations, Information Technology, and Finance & Administration at 31 each—ensure day-to-day continuity. Sales & Support (28), Quality (26), and an "Other" category (38) round out the structure, creating a balanced mix of technical and business functions.
Duolingo maintains a distributed footprint anchored by its Pittsburgh headquarters, which houses roughly 287 employees, or one-third of total staff. A sizable presence in New York City (186 employees) strengthens access to media, finance, and talent pools. Smaller hubs in Seattle and San Francisco host 27 employees each, supporting engineering and partnership initiatives on the West Coast. Additional clusters in Detroit, Boston, Los Angeles, Washington, D.C., and Chicago range from 9 to 14 employees apiece, while about 55 team members are spread across other remote locations, illustrating a flexible approach to workforce placement.
