BrowserStack, a startup that does website testing for DevOps teams, said today that it raised $200 million in new funding at a $4 billion valuation.

The Series B round was led by Bond Capital, Mary Meeker’s investment capital firm, and was joined by Insight Partners and existing investor Accel.

BrowserStack’s platform is a software-as-a-service platform for DevOps teams to test web pages across different devices, especially new classes of devices such as Smart TVs and wearables, and new mobile devices and operating systems. As the combinations of devices, operating systems and browsers become more complex, so does the potential nature of the bugs that can crop up.

Founded in 2011, BrowserStack automates device testing by giving teams access to real devices in the cloud and run their software against them by allowing them to test more and test fast. This increases the likelihood that DevOps teams discover bugs or issues before they become a problem in the field.

BrowserStack’s first version helped developers test their websites on Internet Explorer 11. Now that has expanded to thousands of combinations of modern devices, browsers and operating systems. This allows DevOps teams to access it through the cloud and eschew the necessity of impossible to scale in-house testing apparatus and instead use its easy-to-access cloud-based infrastructure.

“Our global footprint of 15 data centers allows us to serve every developer from a location as close as possible to them,” said Nakul Aggarwal, co-founder and chief technology officer of BrowserStack. “This reduces latency, which saves developers time, and helps them release fast. We will continue to invest in our platform to ensure every developer has an amazing experience.”

The company’s customers include companies such as Google LLC, Amazon Inc., Microsoft Corp., Twitter Inc., Tesco Plc, Ikea and Spotify AB.

BrowserStack intends to use this new investment to continue to develop its product offerings, support strategic acquisitions and continue to grow its operations. One recent acquisition was visual testing and review firm Percy. With Percy, developers can run visual automated functional tests of their software on BrowserStack’s cloud platform.

“We are going to double down on solving new developer problems in the space of DevOps testing,” said Ritesh Arora, co-founder and chief executive of BrowserStack. “Our recent acquisition of Percy, a visual testing platform, was just the start. We will accelerate the rate at which we take new products to market through acquisitions and investment in our product and engineering teams.”
