An investment of $130 million has boosted the total capital of cloud communication innovator Twilio to more than $233 million. The Series E round was led by T. Rowe Price and Fidelity Investments, and included participation from Salesforce Ventures, Draper Fisher Jurvetson (DFJ), Arrowpoint Partners, Amazon.com, and Altimeter Capital.

Twilio CEO Jeff Lawson praised the way Fidelity and T. Rowe Price understood his company’s “developer-first, platform business model.” Twilio plans to use the new capital to speed up its product roadmap, particularly its Real-time Communications Suite; pursue new markets internationally; and expand its presence in the enterprise.

Twilio provides developers with APIs that make it easier to add voice, messaging, and video functionality into their mobile and web apps. The company launched its Programmable Voice solution in 2008, and now gives builders access to SMS, MMS, VoIP, authentication, video, and IP messaging. Twilio will make its FinDEVr debut at FinDEVr 2015 in San Francisco in September.

Recent headlines for Twilio include the launch of Twilio IP Messaging in May, and Twilio Video in April. In February, Twilio made its first acquisition, purchasing authentication specialist, Authy, for an undisclosed sum. Twilio counts among its customers companies as diverse as Home Depot and Uber, Box and Coca-Cola.

In May, Twilio announced a $50 million development fund. In partnership with Bessemer Venture Partners, Redpoint Ventures, and DFJ, the fund will kickstart companies that have built solutions based on Twilio’s technology. The first company to be funded was conference calling app, Speakeasy, to the tune of $5 million.

Twilio is headquartered in San Francisco, and has offices in New York, London, Estonia, Columbia, Germany, Hong Kong, and Ireland. Join them at FinDEVr 2015 San Francisco next month.
