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.
Resolve AI builds an agentic AI Production Engineer that handles alerts, investigates incidents, and performs root cause analysis on production systems - reducing on-call toil for engineering teams at companies like DoorDash, Coinbase, and Snowflake.
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.
