$150 million for Twilio IPO

Twilio, a San Francisco company that makes mobile and Web applications, raised $150 million Wednesday in its initial public offering, pricing the shares above the marketed range.

The company said it priced 10 million Class A shares at $15 each, after offering them for $12 to $14 apiece. The shares will start trading Thursday, listed on the New York Stock Exchange under the symbol TWLO.

At the IPO price, Twilio has a market value of about $1.23 billion.

Backed by Bessemer Venture Partners, Twilio is only the second venture capital-backed technology company to go public this year, and the first in the Bay Area.
