Appen, a global data-annotation and AI training vendor, employs about 1,600 people. Recent records show 78 hires and 176 departures, producing a net contraction in overall headcount. The company’s staffing profile highlights a blend of technical, operational, and client-facing talent that supports its crowdsourced data and machine-learning services.
Marketing & Product is the largest department with roughly 361 employees, representing a little over one-fifth of total staff. Engineering follows closely at 320 employees, underscoring the emphasis on building and maintaining data-collection platforms. Operations (194), Business Management (167), and Finance & Administration (152) form the next tier, while Consulting, Sales & Support, and an "Other" category collectively account for another 405 employees. Smaller specialist groups such as Banking & Wealth Management and Publishing make up the remainder, keeping the overall department mix diverse but weighted toward product development and delivery.
Appen’s workforce is highly distributed: approximately 1,396 employees are classified under "Other," indicating a sizable remote or globally dispersed contingent. The largest identifiable hub is Seattle with 52 employees, followed by San Francisco (31) and several Texas cities—Dallas, Houston, Austin, and San Antonio—that each host 10–25 staff members. Sydney, the company’s original headquarters, retains a modest presence of 21 employees, while New York and Chicago round out the list with small teams. This structure suggests a remote-first operating model supported by several compact regional offices.
