1stdibs, an online marketplace for luxury goods, has hired David Rosenblatt as CEO. The 10-year-old marketplace site sells high-end antiques, art, vintage jewelry and fashion via a network of dealers around the world.

Rosenblatt was CEO for online ad firm DoubleClick prior to its acquisition by Google Inc. in 2008. After the acquisition, Rosenblatt led Google’s global display advertising team before leaving the company in 2009.

He is chairman of Group Commerce, a group buying ad platform, a position 1stdibs says Rosenblatt will retain as CEO of the marketplace. Rosenblatt also serves on the boards of Twitter and InterActive Corp., which owns ShoeBuy.com, No. 87 in Internet Retailer’s Top 500 Guide, and the Ask.com search engine.

“David’s expertise in building technology-based businesses, along with Benchmark’s track record in backing entrepreneurs who are determined to transform markets, is virtually unmatched,” says Michael Bruno, 1stdibs’ founder.

1stdibs.com also announced it has received new investment from Benchmark Capital but did not disclose the amount. Benchmark Capital partner Matt Cohler joins 1stdibs.com’s board of directors.

The marketplace says it will use the capital to expand its products and its global presence. It also plans to hire more executives. The marketplace  says it  sells more than 6,000 items per month and works with more than 1,200 dealers.
