Adam Haney
CTO at Bellhops

“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.”

Calvin-French Owen
CTO/Co-founder at Segment

“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.”

John Duff
Director of Engineering at Shopify

“CircleCI lets us be more agile and ship product faster. We can focus on delivering value to our customer, not maintaining CI infrastructure.”

Arthur Neves
Developer at Shopify

“One of my favorite things about CircleCI is that their team really cares about making sure their customers get maximum value out of their product.”

Ian Lotinsky
CTO at LearnZillion

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

Hemal Shah
Product Manager for Mobile Developer Tools at Fabric

“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

“The ultimate test for us is taking our code on the road. Every piece of code gets a road test before it is merged into master. CircleCI allows us to be confident in the software we build before taking it out for a drive.”

Matti Schneider
Core Team Member at beta.gouv.fr

“There are so many challenges in building working software within government that you deliver to the public in 6 months. CircleCI lets us focus on the things that matter.”
