LinkedIn is seeking a new premises in Dublin to base its international headquarters as the company expands its overseas operations, two people with knowledge of the matter said.

According to news agency Bloomberg the people, who asked not to be identified, said IDA Ireland was working with the professional social network on a plan to lease as much as 15,000sqm in Dublin.

Richard George, a spokesman for the Mountain View, California-based company, declined to comment.

LinkedIn, whose shares have more than tripled since the company’s 2011 initial public offering, is aiming to grow its international membership as part of an attempt to expand its revenue base.

The company, which first opened a Dublin office in 2010, now employs more than 450 people here, Mr George said.

“Dublin is now host to a major global tech cluster and IDA works continuously with a wide range of companies on potential opportunities available to their operations in Dublin,” IDA Ireland said in an e-mail. It declined to comment specifically on LinkedIn’s possible expansion.

Ireland’s corporate tax rate and tax credits for research-and-development investments has attracted companies like LinkedIn, Facebook and Google to the country.

LinkedIn’s international sale rose 54% to $176.1m in the fiscal fourth quarter and accounted for 39% of the company’s total take, 1% more than a year earlier.
