Viraat Das
Viraat Das is the cofounder and CEO of Exla, a Y Combinator (Winter 2025) startup building AI infrastructure. A former Amazon machine learning engineer who finished his Purdue computer science degree in two and a half years, he first shipped an SDK that squeezes large transformer models onto edge hardware like NVIDIA Jetsons, then aimed the company at Libra, an always-on AI site reliability engineer that reads production logs, traces failures to the deploy that caused them, and opens fix pull requests while the team sleeps.
Corelayer
Corelayer is an AI-native production support platform - an 'AI on-call engineer' - built for regulated, data-heavy industries like finance, healthcare, and insurance. It continuously watches alerts, logs, infrastructure, and the underlying data itself, then uses multi-agent AI to trace anomalies to root cause and suggest fixes. Founded in 2025 by former Goldman Sachs data-infrastructure engineers Mitch Radhuber and Shipra Jha, the company is part of Y Combinator's Winter 2026 batch.
Vibranium Labs
Vibranium Labs is a New York-based AI company building Vibe AI, an agentic 'AI Site Reliability Engineer' that acts as the first responder to IT incidents. Its Vibe OnCall platform pages AI agents to detect, triage, and resolve outages before human engineers are woken up, integrating with tools like Slack, PagerDuty, Datadog, Jira, and ServiceNow. The company says its agents cut mean time to resolution by up to 85%, and positions itself as an AI-native alternative to PagerDuty and Opsgenie. Founded by Sang Lee (ex-Google, ex-AWS) with FiscalNote co-founder Tim Hwang, it raised $4.6M in seed funding in September 2025.
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.
Resolve AI
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.
