H Company is a next‑generation AI research and product company pioneering the future of autonomous, agentic AI. Founded to build intelligence that acts, H Company is creating the foundational infrastructure for autonomous AI systems that drive real‑world outcomes across industries.

Our Models team builds the foundational models that power our cutting‑edge agentic technology. We focus on training techniques to optimize model capabilities specifically for agent applications, allowing us to achieve the best performance at a given inference cost. Our work spans the development of Large Language Models (LLMs) and Vision‑Language Models (VLMs), enabling agents to perceive, understand, and act within complex environments.

We are deeply involved in enhancing these models through training methods with a focus on improved instruction following, tool use, and interaction with dynamic environments via large‑scale reinforcement learning and reward modeling. We operate at the intersection of research and product, translating cutting‑edge research into practical solutions that drive the next generation of AI. We are looking for bright, motivated individuals to join our ranks and shape the future of superintelligent AI.
