Scale
Data-labeling incumbent extending into agent evals and RL environments
Scale AI is the original data-labeling powerhouse for AI labs and enterprises, now building RL environments and agent evaluation products under its agents and RL environments group. After Meta's 2025 investment and the departure of CEO Alexandr Wang, it lost some lab customers but continues to push into environments.
