Omnicom Group’s Goodby Silverstein & Partners continues to add clients and ramp up staff at its fledgling New York operation.

The shop, which handles YouTube, recently picked up a new piece of business from parent company Google but is apparently under a gag order not to say more about it.

It has also added a startup to its client roster, Pledge Music, a crowd-funding website where fans can help finance albums and get incentives in return like tickets to live shows.

Meanwhile, the agency has added two creative leads, naming Scott Hayes as senior copywriter and Jamie Carreiro as director of innovation.

Hayes was previously with Wieden + Kennedy, where he worked on both ESPN and Nike assignments. Carreiro, with a background in computer science and filmmaking was previously a producer/director at Essence TV, a unit of Essence magazine.

GSP, based in San Francisco, opened its New York office in January. It was initially co-led by executive creative director Christian Haas and Managing Director Nancy Reyes, two GSP west coast transplants. In March Tom Morton joined the effort as head of strategy and as a third co-leader. Morton was previously Chief Strategy Officer at Havas Worldwide New York. A month later it brought on Steve Wakelam and Nick Pringle as creative directors. The duo had served in similar roles at DDB Sydney.

In addition to Google and YouTube, Comcast is a charter client.

The New York operation, with a staff of 13 is now working out of temporary facilities while new offices are being readied on Varick Street in the city’s downtown area. That move is set for later this year.

In separate news outside of New York, GSP confirmed Friday that it has been tapped by Princess Cruises to create a new ad campaign that will bow in early 2014.
