Last year we made a seed stage investment (through BulletTime) in Twilio. Now with our investment in SevenLayer we have doubled down on the unified communications space. Six months after the original seed stage investment in Twilio the company received an additional $3.7 in their series A from Union Square Ventures and The Founders Fund. The company was founded by Jeff Lawson, formerly of Amazon Web Services (AWS), with the goal of marrying the world of voice to the world of web applications. Today Twilio is supported by 6,000 developers, who have built 1,000 applications using their API. Clients include Sony, Intuit, Heineken, Salesforce.com, Cheetos, Tumblr and 37Signals.
