Twilio, which provides APIs that enable developers to embed voice, messaging and video, raised $150 million by offering 10 million shares at $15, above the range of $12 to $14. Twilio is the year's first "unicorn" to go public, and the first IPO to price above its proposed range since December.
Twilio plans to list on the NYSE under the symbol TWLO. Goldman Sachs and J.P. Morgan acted as lead managers on the deal.
