Sang Lee

Sang Lee is the co-founder and CEO of Vibranium Labs, a New York startup building Vibe AI, billed as the first 24/7 AI site reliability engineer. A former Google and AWS engineer who lived through too many 2 a.m. outage firefights, Lee is building an agentic AI teammate that detects, triages, and resolves IT incidents before a human ever wakes up. In September 2025 the company raised $4.6M in seed funding led by Calibrate Ventures and Mirae Asset, with backing from a16z, Franklin Templeton, and others, claiming up to an 85% cut in mean time to resolution and counting Shutterstock among its clients.
