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.
