Scale AI

Scale AI is a data infrastructure company that provides high-quality training data, evaluation, and AI testing services for companies building AI models and applications. Founded by Alexandr Wang, Scale AI specializes in data labeling, annotation, and curation at the quality levels required for training frontier AI models.

Scale has evolved beyond data labeling into a broader AI platform: Scale's SEAL (Safety, Evaluations, and Alignment Lab) benchmarks assess AI model capabilities, its Donovan platform serves government and defense AI applications, and its enterprise platform helps organizations prepare proprietary data for AI use.

In the agentic economy, Scale AI provides the data quality infrastructure that determines how capable AI agents can become — because the quality of training data directly bounds the quality of AI model outputs and agent behavior.
