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.
Andrew Miklas co-founded PagerDuty with two Amazon colleagues in 2009, built the original high-availability architecture as founding CTO, and shepherded the company from a Hacker News beta post to a $1.8B NYSE IPO. After a stint as an early-stage investor at s28 Capital, he returned to Y Combinator - where PagerDuty got its start in the Summer 2010 batch - as a General Partner in May 2025, fifteen years after first walking through YC's doors as a founder.
