Outlier

Outlier is a Scale AI-operated platform that connects vetted subject-matter experts and freelance knowledge workers with AI companies that need human feedback, data labelling and model evaluation for large language models. The platform handles onboarding, identity verification, task allocation, workflow execution, quality control and contributor payments, making it a structured human-in-the-loop operations layer for AI development teams. The company generates revenue through enterprise contracts with AI companies, research labs and other organisations building or refining models. Commercially, it operates as a managed marketplace and workflow platform: clients pay for completed tasks, evaluation work and specialist expertise, while contributors are paid for their labour. Outlier captures value through service fees and margin between client billing and contractor payouts, with premium economics for scarce expert domains such as coding, maths and science.
