John Jae Woo Lee
I build products millions of people use — from AAA games at Riot to blockchain infrastructure securing $50B+ at Chainlink. Now I help founders in iGaming, prediction markets, and consumer marketplaces ship faster and scale smarter.
Based in San Francisco, working with companies globally.
Track Record
I've spent two decades operating at the intersection of breakthrough technology and high-stakes execution. My career began at Amazon, building early AI and language model foundations within Alexa and the devices ecosystem — years before LLMs captured mainstream attention. That experience forged a conviction I still carry: the real leverage in any technology wave lies in the infrastructure layer, not the application layer. From Amazon, I joined Caffeine.tv as a founding engineer — a social live-streaming platform advised by Ben Horowitz — before leading engineering at Tally, redesigning how consumers eliminate credit card debt.
At Riot Games, I delivered two AAA titles, scaling engineering teams and systems to serve a globally distributed player base of millions. At Chainlink Labs, I led 85+ engineers across a critical slice of Web3 infrastructure — delivering 80+ blockchain integrations and supporting protocols with over $50B+ in total value locked. Most recently, as VP of Product & Engineering at Sky Mavis, I directed a 90-person global organization, shaping the company's AI roadmap, tokenomics architecture, and game labs strategy while tripling monthly active developers.
This experience maps directly to modern sportsbooks, prediction markets, and consumer marketplaces: real-time systems that can't fail, economic models that drive engagement, and consumer trust at scale. At Sky Mavis, I designed tokenomics for platforms where users make real-money decisions daily. At Chainlink, I built the oracle infrastructure that prediction markets depend on for tamper-proof data feeds.
Beyond operating roles, I'm a competitive gamer myself — reaching the top 0.05% in World of Warcraft and Immortal rank in Dota 2. I understand the psychology of stakes, risk, and what makes people engage with high-reward systems. Today I run Supercharged, bringing this experience directly to founders building the next generation of iGaming, prediction markets, and consumer platforms.
