Market leader in AI training data and model evaluation, serving top-tier AI labs, tech giants, and U.S. government agencies

Scale AI is a data infrastructure company founded in 2016 that specializes in generating, annotating, and evaluating the training data needed to build and improve artificial intelligence models. The company offers a platform that combines human labelers with automated tooling to produce high-quality labeled datasets across modalities including text, images, video, audio, and 3D sensor data. Scale serves as critical infrastructure for AI development, enabling companies to move from prototype to production-grade AI systems at scale. Scale AI's customer base spans some of the most prominent names in AI and technology, including OpenAI, Meta, Microsoft, and various U.S. government agencies. The company has expanded beyond traditional data labeling into model evaluation and red-teaming services, helping organizations assess the safety, accuracy, and alignment of large language models. Its Reinforcement Learning from Human Feedback (RLHF) capabilities have become particularly valuable as generative AI has surged in prominence. It plays an increasingly relevant role in the broader AI ecosystem that underpins modern advertising technology. AI-driven ad targeting, creative generation, and audience modeling all depend on the kind of high-quality training data and model evaluation that Scale provides. The company has achieved unicorn status with a valuation exceeding $13 billion and is widely considered one of the most strategically important AI infrastructure companies in the world.
