Mercor hit $500M Revenue Run Rate

Mercor has become one of the fastest growing startups in history, scaling from just $1M to a $500M ARR run rate in only 17 months.

Growth is accelerating rapidly: the company posted 11% week-over-week growth in July, 18% in August, and 19% in September. Mercor is positioning itself as a category-defining AI marketplace, leveraging reinforcement learning (RL) to transform the economy into a real-time environment where humans and AI agents collaborate at scale.

The company’s core innovation lies in applying reinforcement learning to knowledge work, where machines excel at optimizing benchmarks while humans define the reward structures that guide automation.

This creates a new paradigm for the future of work, in which professionals—from software engineers and doctors to lawyers, bankers, and consultants—train, guide, and refine AI agents. By combining autonomous AI with human expertise, Mercor is building a next-generation platform that enables massive productivity gains and unlocks an entirely new labor category.

Mercor’s financial momentum underscores its disruptive potential. The company now pays out over $1M per day to participants in its AI-powered marketplace, fueling rapid adoption across industries.

With ARR already at $500M, Mercor is setting a new benchmark for hypergrowth in the AI sector. Its model of integrating AI agents with domain experts not only redefines knowledge work but also positions Mercor as a foundational player in the reinforcement learning economy.
