IPO window is open right now. Lets see how long it goes.
Rubicon, which raised $81.3 million in its IPO and saw its stock jump 33 percent in its first day of trading Wednesday, is a so-called supply side ad tech company. It provides an automated platform for publishers to sell its inventory to a network of ad buyers. Its public offering was a successful sequel to the September IPO of Rocket Fuel and the October IPO of Criteo, both of which are so-called demand-side firms that offer tools and services to advertisers.
