“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. ”
