incident.io is a software reliability platform for investigating, responding to, and preventing incidents. It ties on-call, response, and status pages together from the first alert to the final fix, with AI assistance throughout.

On-call - alert routing, schedules, and escalation with AI filtering of noise.
Investigations - agentic root-cause analysis that scans signals and proposes hypotheses during the incident.
Response - run incidents from Slack or Teams with roles, workflows, call transcription, and automation.
Status pages - internal and external pages updated automatically as the incident progresses.
Nexus - a model of the production environment built from incidents, systems, and team data.
Workflows, policies, and insights - consistent response processes plus learning across incidents.

It is used by engineering and SRE teams at companies such as Netflix, Etsy, Zendesk, and Airbnb that need coordinated response when production breaks.
