Brian Yoo is Chief Business Officer at FriendliAI, an AI inference platform that helps enterprises deploy and scale large language models faster and cheaper. Before joining FriendliAI in April 2026, he spent nearly a decade as COO at Moloco, where he scaled the AI-driven advertising company from 10 employees to 600+ and grew revenue over 500x to $250M+, helping it reach a ~$4 billion valuation. A Cornell-trained operations research engineer turned business operator, Yoo brings deep expertise in scaling AI-native companies through go-to-market strategy, financial operations, and global team building.
Byung-Gon Chun is the CEO and Co-founder of FriendliAI, and a professor of Computer Science and Engineering at Seoul National University currently on leave. A systems researcher turned founder, he is best known for inventing continuous batching - the scheduling technique that became the default standard in every major LLM inference engine, from vLLM to TensorRT-LLM. His lab published the foundational ORCA paper at OSDI 2022, and he then turned that academic insight into FriendliAI, an enterprise AI inference platform that raised $26.7M and supports over 550,000 models from Hugging Face. With a career spanning Intel, Yahoo!, Microsoft, and Facebook, Chun brings rare depth across both research and production AI infrastructure.
