Scale AI

AI data infrastructure and enterprise software company originally focused on data labeling and now spanning RLHF, model evaluation, and a GenAI Platform for deploying custom enterprise and government AI applications. Operates labeling subsidiaries Remotasks (computer vision, autonomous vehicles) and Outlier (LLM annotation), and runs the Safety, Evaluation and Alignment Lab — expanded in March 2026 into Scale Labs — which co-created benchmarks including Humanity's Last Exam. Holds contracts with the US Department of Defense and the US AI Safety Institute. Founded in 2016 by Alexandr Wang and Lucy Guo; in June 2025, Meta invested $14.3B for a 49% non-voting stake at a $29B valuation and Wang departed to lead Meta Superintelligence Labs, with Chief Strategy Officer Jason Droege serving as interim CEO until former Google Cloud COO Francis deSouza was appointed chief executive in July 2026. Scale laid off approximately 14% of staff in July 2025 after major AI lab customers including OpenAI, Google, and xAI paused or reduced engagements over data confidentiality concerns. Scale remains an independent company.
