AI researcher Danijar Hafner builds startup on agents that plan ahead

Danijar Hafner, known for his work on world models and reinforcement learning including the Dreamer series, has quietly founded a new startup in San Francisco. The stealth-mode company is developing AI agents designed to plan ahead for unexpected situations rather than just react.

Why it matters: Hafner's background in model-based reinforcement learning and world models puts him at the center of a push to make AI agents more robust in unpredictable, real-world settings, a persistent weakness of today's LLM-based agents that mostly react step by step. A well-known researcher launching a company around this problem suggests planning and world-modeling techniques may be moving from academic benchmarks toward commercial agent products.
