Scale marked its tenth anniversary, reporting more than 700 customers served, 15 billion human decisions applied to model development, work across 150 languages and locales, and over $1 billion paid to contributors.

Scale reported that 2025 was its strongest financial year, with more than $1 billion in new business, profitable data operations, and accelerating applications and government work.

Scale announced expansion across New York, London, Washington, D.C., Doha, and St. Louis to support enterprise, government, and international growth.

Scale updated its mission to developing reliable AI systems for the world’s most important decisions, reflecting its expansion from data infrastructure into applications and evaluation.

Scale reduced approximately 200 employee roles and contractor assignments after determining it had expanded its generative-AI capacity too quickly, while prioritizing enterprise, government, and international growth.

Scale provided evaluation infrastructure for the White House-supported Generative Red Team Challenge at DEF CON 31, testing frontier models with thousands of participants.

Scale announced a restructuring that reduced its employee workforce by roughly 20 percent after expanding too quickly during the prior growth cycle.

Scale established a dedicated St. Louis operations center to develop skilled U.S. data and evaluation workforces for government programs.

Alexandr Wang and Lucy Guo founded Scale in San Francisco and entered Y Combinator to build an API for routing human work, which evolved into AI data infrastructure.
