It also easily surpassed management's outlook for the quarter, which was guiding for 50% growth at the high end of management's forecast. Robust customer growth helped drive the top line. Twilio's active customer count grew to 240,000, up 20% year over year.

Twilio also expanded its offerings by acquiring business messaging start-up Zipwhip, setting the stage for future cross-selling opportunities. Twilio's growing ecosystem of cloud-based communications tools is second to none. While the stock will continue to be volatile, the business is doing just fine. 10 stocks we like better than TwilioWhen our award-winning analyst team has a stock tip, it can pay to listen.
