Cloud-based communications provider Twilio announced Wednesday the close of a $130 million Series E investment round -- placing its valuation at just over $1 billion.
Fidelity and T. Rowe Price led the round, along with new investors Altimeter Capital Management and Arrowpoint Partners, as well as Amazon.com and Salesforce Ventures.
"We're excited to work with Amazon.com and Salesforce Ventures -- true pioneers in cloud, software and infrastructure as a service," Twilio CEO Jeff Lawson said in a statement. 'We can't wait to see what our customers build next."
Twilio plans to put the new capital toward further enterprise expansion, as well to help implement the security technology Twilio acquired in February when it purchased Authy.
At the time, Twilio said it planned to use Authy's API to offer embeddable two-factor authentication and phone verification to applications running Twilio's cloud-based communications services. In May, Twilio updated the API to gives users the ability to approve a login request from a push notification.
Since its launch in 2008, Twilio has built a suite of services designed to bring telephone capabilities to mobile apps, where developers can tap into its bevy of APIs for SMS, MMS and text message communication. The company launched video calling services in March, a move seen as a key addition to its communications platform.
Twilio also operates an comprehensive telephony network of its own that's used to connect its customers' apps to global telephone networks. Twilio counts companies such as Uber, The Home Depot, Salesforce, Intuit and Coca-Cola as customers.
