CircleCI, the leader in Continuous Integration and Continuous Delivery, today announced it has closed a $6 million round of funding round led by DFJ.

Continuous Delivery is the modern development practice, used by companies such as Amazon, Google, and Facebook, that speeds up development teams by allowing software development teams to deliver features to their customers in minutes rather weeks.

'CircleCI makes developers more productive,' said Paul Biggar, cofounder and CEO of CircleCI. 'Development speed is critical in today's competitive development landscape, and maintaining this speed is difficult as apps grow larger and more complex. This investment allows us to continue to deliver the features developers need to continuously integrate and deliver software faster and far more easily on a global scale.'

Automating and accelerating software delivery using CircleCI lets developers speed time-to-deploy, boost developer productivity, and improve software quality. CircleCI's fast, scalable Continuous Integration and Continuous Delivery service frees developers from building and maintaining their own agile infrastructure and allows them to focus on their core product.

'In a mobile world where customers' expectations are high, there's excitement around developer tools. These tools empower developers to focus on building core product rather than the infrastructure around it. With CircleCI, the company's unique focus on making their customers -- software developers -- makes for a timely offering,' said Bubba Murarka, who led the investment for DFJ and joins CircleCI's board. 'The market has welcomed CircleCI, and the demand for these tools is reflected in the durable traction the company achieved prior to funding, having grown over 25x since their initial seed round. Today, CircleCI boasts over 1,000 customers worldwide. Customers love their product, and all of us at DFJ are thrilled to work with them.'

CircleCI previously raised a seed round of $1.5 million in February 2012 led by the founders of Heroku, Baseline Ventures and Harrison Metal. Notable angel investors included Heroku and Heavybit founder James Lindenbaum and renowned Continuous Delivery pioneer Eric Ries.

This transaction represents the single largest round of funding in the Company's history. In conjunction with this financing, DFJ's Murarka will join CircleCI's Board.
