Fan-Yun Sun

I'm Fan-Yun, CEO of Moonlake AI, where we're building AI systems that reason and plan.

Our work sits at the intersection of reinforcement learning, agents, and long-horizon decision-making. The goal is making AI systems that can do more than respond.

I'm also finishing my CS PhD at Stanford. Before Moonlake, I was a research scientist at NVIDIA and spent time at Mila researching RL systems. I studied CS at National Taiwan University before moving to Stanford.

We're hiring!
