Opera Software is becoming more of a Silicon Valley company.
It has expanded its US operations, tripling its office space to 60,000 square feet through a new office and its acquisition of Skyfire, the company said Thursday.
"Silicon Valley has become one of Opera's most strategic locations to do business and grow our talent base," said Opera Chief Executive Lars Boilesen in a statement. "We will continue our expansion in this region by hiring people in all areas and generating more revenue than ever."
The maker of the Opera browser is based in Oslo, Norway, but its staff of 950 is spread among several offices around the globe. About 200 employees work in three offices in California -- San Francisco, San Mateo, and Mountain View -- and Opera plans to expand that to 300 in 2014.
Although it's best known to consumers as a browser maker, Opera is becoming an online advertising company, too, with operations under its Opera Mediaworks brand. That includes an ad delivery platform, which can be used to host ads online, and three ad networks that link together those with ads to sell with online publishers that have a place to show them.
Opera Mediaworks revenue doubled in the second quarter of 2013 compared to the year-earlier quarter, Opera said.
At the same time, the company dropped much of its own programming work by shifting from its own Presto browser engine to Google's Blink, the WebKit-derived foundation of Chromium.
