New York's Coolest Startup Offices

New York's booming Internet sector is spawning some workplace wonderlands. For proof, look no further than the in-office DJ booth or the rooftop lounge in this roundup of Manhattan's swankiest startup spaces, released by SecondMarket, an online marketplace for alternative investments, with headquarters in New York's financial district.

And SecondMarket isn't the only one shining a light on the recent emergence of Silicon Alley chic.

The Roger, a bi-monthly magazine that launched in February, highlights the en vogue interiors of New York's hottest startups. Mashable's Startup Spaces and BusinessInsider's Office Tours regularly peek inside young tech firms housed in Manhattan. There's even the annual Walkabout NYC, a five hour walking tour of the spaces that started during last year's Internet Week.

According to a report by real estate services company CBRE Group, the tech and media sector accounted for roughly 13 percent of New York office space leasing last year, up from 11 percent in 2005.
