incident.io

incident.io operates a software platform that helps engineering teams declare, coordinate, and resolve technical incidents such as outages and service degradations. The company was founded in 2021 in London by Stephen Whitworth, Pete Hamilton, and Chris Evans, three engineers who had previously built internal incident-response tooling at the digital bank Monzo. It is headquartered in London, with a North American office in New York opened in 2022.

The platform is built around Slack and Microsoft Teams workflows and spans on-call scheduling and paging, incident response automation, post-incident learning, and public status pages, with more recent additions of AI features for triage and investigation. incident.io counts Etsy, monday.com, and Skyscanner among its customers and competes with established alerting and incident tools including PagerDuty, Opsgenie, and FireHydrant.

The company raised a $5.5 million seed round in late 2021 with participation from several Monzo founders, followed by a $28.7 million Series A in 2022. In April 2025 it raised a $62 million Series B led by Insight Partners at a valuation of about $400 million, bringing total funding to roughly $95 million. incident.io employed around 200 people as of 2026.
