Scale AI Expands Data-Labeling Dominance Globally

Scale AI, founded by Alexandr Wang in 2016, has expanded into a data-labeling powerhouse valued over $20 billion by 2025, employing more than 10,000 people worldwide. This year it secured a U.S. Department of Defense Thunderforge contract, launched the Scale Evaluation benchmarking platform in April 2025, and attracted scrutiny after Meta’s June 2025 49% stake.
