Hillclimber

Hillclimb develops a virtual laboratory platform for AI models to continuously experiment and learn, aspiring to become autonomous research scientists. It creates infrastructure for production-grade reinforcement learning environments, enabling AI agents to rigorously test hypotheses and refine research abilities. This delivers sophisticated training data crucial for advancing frontier AI.

Founded in 2025 by Jun Park and Ibrakhim Ustelbay, hillclimb responds to the escalating demand for sophisticated AI training data. Park, a former DeepMind research engineer, and Ustelbay, founder of Headstarter, observed that advanced AI systems critically rely on curated, intellectual data from human superintelligence. This insight propelled the company's inception.

Hillclimb partners with frontier AI laboratories, supplying specialized training data pipelines capturing problem-solving intelligence from elite human experts, particularly in mathematics. Its vision accelerates AGI by fostering environments where AI can autonomously extend scientific frontiers. This transforms how advanced AI models are trained and developed.
