Byung-Gon Chun

Byung-Gon Chun is co-founder and CEO of FriendliAI, an inference platform for serving large models efficiently. A systems researcher turned founder, he builds runtimes aimed at production LLM serving rather than training clusters alone.

Research systems into a company

Chun's personal site and company materials emphasize systems work on large-scale AI serving. FriendliAI grew out of that research instinct: make inference faster and cheaper with a dedicated engine and cloud offering.

Seed extension and inference focus

In 2025 FriendliAI announced a $20M seed extension led by Capstone Partners after an earlier Series A in Korea. Public posts describe redefining AI inference for enterprises that feel GPU bills and latency SLOs at once.

On serving as the product

He talks about inference - not another foundation model - as the product layer where most companies will spend. That positioning keeps FriendliAI in AIR's runtime and hosting conversations beside larger US clouds.
