Updated June 15, 2026Scale AI is the leading AI data infrastructure company founded in 2016, providing data annotation, model evaluation (SEAL benchmarks), and enterprise AI deployment services. With $2 billion in 2025 revenue (130% YoY growth) and a $29 billion valuation, Scale serves frontier AI labs, enterprises, and the US Department of Defense.
In June 2025, Meta invested $14.3 billion for a 49% non-voting stake, triggering major changes: founder/CEO Alexandr Wang (formerly the youngest self-made billionaire) left to become Meta's Chief AI Officer, and Jason Droege became interim CEO. OpenAI, Google, and xAI reduced engagements over data confidentiality concerns tied to Meta's ownership. Scale laid off 200 employees (14% of workforce) in July 2025.
Scale's SEAL leaderboards have become the industry standard for independent AI model evaluation. The company holds $200+ million in US defense contracts including a $100 million Pentagon OTA for Top Secret/SCI AI deployment. Scale operates Remotasks and Outlier platforms with 240,000+ gig workers for data annotation.
