CircleCI, the world's leading continuous integration and delivery platform, today announced it has closed a $31 million Series C round of funding led by Top Tier Capital Partners alongside Industry Ventures and Heavybit, who join existing investors Scale Venture Partners, Baseline Ventures, Harrison Metal, and DFJ Ventures. Prior to this round, the company had raised a total of $28 million.

"In a few short years, we have become one of the largest build systems on the planet," said Jim Rose, CEO of CircleCI. "With this latest round of funding, we can now harness the incredible data and insights we've collected to invest in prediction and intelligent automation, helping all users of CircleCI build better software, faster. Our mission is to give everyone the ability to build and deliver software at the speed of imagination."

CircleCI delivers scale and speed that is unmatched in the software development industry. With over 7 million builds processed every month, CircleCI is one of the fastest-growing developer tools in the world. Successful companies of all sizes trust CircleCI to build, test, and deploy their software including Spotify, Facebook, Lyft, Autodesk, Adobe, Instacart, Shopify, Percolate, Blue Apron, Kickstarter, Stitch Fix, Coinbase, Zenefits, Heroku, Udemy, Docker, and many others. CircleCI plans to use the new investment to radically reduce the time from idea to delivery via automation and machine learning.

Due to strategic new hires in 2017, CircleCI brought the company's total workforce to more than 120 employees. 2017 also saw a complete replatforming of CircleCI's infrastructure. CircleCI 2.0 has delivered dramatically reduced build times and increased flexibility for customers. Among other signs of momentum, CircleCI logged the following milestones:
