Welcome to Shibo's home on the Internet.
Hello, my name is Shibo Zhou. I am a computer programmer and make a living by writing code at Exa, where I work on the knowledge engine. More specifically, I work on continuously synthesizing information from across the web and beyond into one of the world’s largest open-domain knowledge graphs, with hundreds of billions of evidence-backed claims. I research and build the construction pipelines and retrieval engines that decide what to trust and how best to search this knowledge. Our goal is to give agents answers to any factual question about the world with unprecedented precision and completeness. Previously, I graduated from Carnegie Mellon University with a degree in Computer Science with a concentration in Robotics.
Before joining Exa, I co-founded a space robotics startup, General Astronautics, backed by Y Combinator (W26) and an angel investment from Paul Graham.
It can retrieve papers from natural language descriptions even when the query is vague or inaccurate. We’ve found that its search performs significantly better than Google Scholar and other major AI powered search engines, such as Perplexity and Parallel.
