Justin Fry is a serial founder and engineering leader with 11 years of experience scaling AI-driven products and organizations, now serving as CTO in Chicago. He has led teams of 250+ engineers, driven multiple exits, and is the primary inventor on six patents spanning LLMs, vocoders, and speech synthesis. Justin has architected and shipped 40+ applications used by Fortune 500 clients, collectively exceeding one billion downloads, and developed foundational LLM work that contributed to major products at Google. He combines deep research proficiency—building low-latency transformer TTS and neural codec backbones—with rigorous operational impact, including dramatic opex and COGS reductions at Mobile Insight. Known for solving “impossible” technical problems, he also built one of the first agentic LLM telephony services that scaled to millions of calls and led to an acquisition. His background in math, physics, and CS underpins a pragmatic, product-first approach to industrializing cutting-edge AI.
