Josh Cho is a founder and software engineer based in Palo Alto with a decade of experience building systems and AI-driven applications. Currently leading Fren, he focuses on shipping LLM apps and experiments that explore practical uses of large language models. A Stanford-trained computer scientist specializing in systems and AI, he blends academic grounding with hands-on product development. Josh is an active open-source practitioner—his GitHub brands him as "a spawning pool of llm apps" and surfaces frequent exploratory projects rather than a single flagship repo. He brings an entrepreneur’s bias for iteration and rapid prototyping, often turning research ideas into usable developer tooling. Outside work, his online presence on GitHub and X highlights a steady stream of experiments that reveal an appetite for unconventional approaches to LLM engineering.
