Accel led the round, with participation from Lightspeed Venture Partners and Sway Ventures -- bringing Split's total venture funding to $9.8 million. Accel partners Ping Li and Steve Loughlin will join the board, along with Lightspeed's Arif Janmohamed.

Pioneering the 'controlled rollout,' Split enables companies to deliver exceptional user experiences by providing a simple, secure way to target features to customers. Through a combination of Split's own feature flags and language-specific SDKs, engineering teams can safely test new ideas on defined audiences. An easy-to-use interface lets anyone in the company handle the rollout process and kill features that aren't working with a single click -- right from the browser. For businesses already focused on continuous integration and continuous delivery, Split helps them finally realize the promise of DevOps (speed, frequency and safety) without compromising quality.

In today's market, companies are continuously investing in new software, and customers expect increasingly seamless digital experiences. Yet too often, businesses release massive updates only to be met with embarrassing bugs, emergency fixes -- and customer churn. By allowing features to be securely tested at any time, Split eliminates this risk.

'For today's software-driven businesses, experience is everything; a continuous make-or-break moment with the customer. With Split, any company building software can get access to the same strategies that industry leaders like LinkedIn, Facebook and Netflix are using to test and deliver new features to their users thousands of times a day,' said Patricio Echague, co-founder and chief technology officer of Split.

Along with transforming the way companies manage feature releases, Split also provides critical new sources of insight: which features are being seen, who they're being seen by, and when feature-level rollout events are happening. Paired with extensive integrations with DevOps and collaboration tools (like Atlassian JIRA, Datadog, Sumo Logic and Slack) these new data streams let business understand exactly how customers are engaging with products. Now, companies can measure the impact of unique software changes on customer growth, experience and retention -- and make better choices, faster. Teams at companies like Segment, WePay and thredUP already use Split to deliver new features, and make stronger, data-driven business choices.

'We see Split not just as a new capability for engineering teams, but a strategy for the whole business,' said Ping Li, a partner at Accel. 'It gives companies both feature-level control over the release process, and new insight into actual customer experiences. By releasing discrete features and targeting them to the right customers, today's companies can become much more agile, responsive, and ultimately, competitive with Split.'

Split is proud to have Accel (an early advocate of the platform) join the board, along with Lightspeed. Arif Janmohamed, partner at Lightspeed, says, 'At LSVP we have a front row seat to the continuous integration and continuous delivery market through our CloudBees investment, and we see Split as the vanguard of the post-CI/CD frontier.'

'With the support of our venture partners, we're poised to continue to help fast-growing companies deliver new experiences to their users at any scale,' said Split co-founder and chief executive officer Adil Aijaz. 'We're looking forward to investing in new hires to continue to build the Split platform, expanding to new languages, and building new integrations and capabilities.'
