“Whether I’m consulting for other businesses or starting a new project myself CircleCI is always on my checklist for setting up the engineering team’s testing infrastructure.”

Adam Haney
CTO at Bellhops

“CircleCI has saved us a ton of time from maintaining our own CI, and we love the ability to both dynamically scale the number of containers and debug manually via SSH when first setting up a project. It’s a great tool.”

Calvin-French Owen
CTO/Co-founder at Segment

“CircleCI makes our products better by allowing us to spend more energy testing them and less time managing a home-grown testing infrastructure.”

Ian Lotinsky
CTO at LearnZillion

“fastlane is built around the principle of continuous deployment. Having a partner like CircleCI that is consistent and reliable enables us to not only deliver the best value to our customers, but deliver it with total confidence.”

Adrian Macneil
Director of Infrastructure Engineering at Cruise
