Case Study: i2 Group reduces build times from 24 hours to 1 hour with CircleCI

CircleCI helps i2 Group reduce maintenance and costs

i2 Group, a Cambridge, UK company that builds intelligence analysis software, was struggling with slow, costly CI/CD processes on self-hosted Jenkins infrastructure. The team wanted to move from a few releases per year to continuous delivery, but build maintenance, executor reliability, and long automated test times were holding them back.

CircleCI helped i2 Group modernize its CI/CD pipeline by replacing Jenkins and optimizing Web and Server builds with parallelism, caching, orbs, and premium support. With CircleCI, some processes dropped from nearly 24 hours to 1 hour, automated test suites fell from 18–24 hours to 1 hour, and executors began spinning up in seconds, reducing maintenance and improving build reliability.
