Gremlin, a San Jose, CA-based company that builds resilient systems through chaos engineering, raised $7.5m in Series A funding.
The round was led by Index Ventures, with participation by Amplify Partners.
Combined with the previously raised seed round, this brings the total amount raised by the company to $8.75m.
Founded by CEO Kolton Andrus and CTO Matthew Fornaciari in 2016, Gremlin builds resilient systems through chaos engineering – a new engineering philosophy that safely injects failure into systems to proactively identify and fix unknown faults.
The company’s new tool simulates how a system would react when encountering challenges, such as network latency, data center outages, etc. With nearly a dozen attacks and more launching soon, Gremlin recreates the most common failures across three categories: Resource, Network, and State. The tool is equipped with security features, including multi-factor authentication and principle of least privilege, as well as an undo button to drive safe, controlled experiments.
The company’s tool allows engineers to see how the system will behave in the face of failure, validates that defenses will work to prevent outages, minimizes the blast radius to allow for safe experimentation in production, and saves time and resources for engineering teams.
Today, the company serves Expedia, Twilio, Confluent, and Remind.
Gremlin is a subscription-based service, with pricing based on per instance or service.
