Toshimasa Ishibashi | Co-founder and CTO at Kaizen Platform

“I set up CI/CD for #ReactNative app this week, I used #CircleCI #Fastlane and connected it to #Firebase Distribution! It works well! Now all tests, builds and code signing are done automatically! #IOS #Android #mobile #ContinuousIntegration #DevOps #FirebaseDistribution”

Iryna Kreichmann | @Lucky_girl_____ at Twitter

“Waking up to a PR sure beats spending the day investigating.”

Sodai Kitamura | Data Science and Engineering at LINE

“CircleCI helps us identify the areas that need improvements and quickly address them — developers only have to worry about building the product.”

Thomas Groutars | Staff Software Engineer at Maze

“We strive to have at least an 80 percent success rate on all of our projects and CircleCI helps us maintain this average — from conception to delivery, we got the changes out in three days.”

Jon Anderson | Senior Software Engineer at Outreach

“There were so many of our customers that were already using orbs … it was so easy that it gave them access to that feature without having to do any additional work.”

Cory Virok | Co-founder and CTO at Rollbar

Anthony Carr-Smith | Software Development Manager at i2

“Switching to CircleCI has allowed our engineers to build and release mobile and web projects with far greater simplicity, speed and performance.”

Matt Wise | Senior Systems Architect at Nextdoor

“The rise of GenAI is putting pressure on developers to test more frequently because every single application needs to be up and running at 100%, making effective CI/CD essential.”

Xavier Portilla Edo | Infrastructure Team Lead at Voiceflow

Valentin Ranshakov | QA Lead at Klara

“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.”

Hemal Shah | Product Manager at fastlane

“Before CircleCI, it would take us an hour and 40 minutes to deploy — currently, it takes us 10 minutes.”

Fergus McDonald | Senior Site Reliability Engineer at Procurify

“The previous CI/CD tool required manual deployments [which] inevitably lead to mistakes, so there were rare cases where the results of testing and design were not implemented; after implementing CircleCI, such omissions have become zero.”

Seiichi Sato | Lead Engineer at Bandai Namco Studios

“We’ve reduced the time needed to manage CI/CD infrastructure, while we deliver new projects with high confidence.”

Austin Brown | DevOps Engineer at Ground X

“CircleCI has significantly simplified setup and maintenance of our test environment and this allows us to run and maintain a stable test suite increasing the team’s confidence in the test results.”

Jason Bosco | VP of Engineering at Dollar Shave Club
