In 2012, PivotDesk helped kick off the trend of online marketplaces for short-term office rentals, a development that caused a shift in how companies lease. With "online dating platforms" and "Ubers" for office space coming out of the woodwork, Bisnow went to PivotDesk's NYC office space for the inaugural edition of our series "Inside A Startup." We poked behind the graffiti-riddled doors of PivotDesk's New York HQs to see where the magic happens.

PivotDesk actually works out of space listed on its online co-working marketplace by Skillshare, NYC general manager Carly Chase (pictured, bottom left) says.

Here's a snap of the co-working space that PivotDesk rents out...through its own platform.

Skillshare took out a lease on the space with the plan to grow into the massive office. But it only occupies the top floor right now, subleasing the downstairs to five separate companies. They've filled it out nicely, as you can see.

Here's Kevin Dempsey, PivotDesk's new business strategist—the cold-caller of the startup's NYC crew—hard at work trying to snag some new clients.

To Kevin's left is Adam, PivotDesk's account executive, who manages existing clients.

PivotDesk's in-office neighbor, Unique Sound, is an online marketplace connecting music composers with content creators.

In true co-working fashion the companies' proximity let PivotDesk help the French startup develop its own web platform, and jump some legal hurdles that PivotDesk itself faced.

PivotDesk's NYC team tries to move every three months to a new PivotDesk space (test-driving the products).

The sweet roof setup drew the NYC team to this pad.

Not to mention the view.
