New York City’s Silicon Alley continues to hold its own against California’s Silicon Valley. In fact, according to CBRE’s recent Scoring Tech Talent report, the overall pool of tech talent is larger in New York than it is in Silicon Valley, and second overall in the United States.

Rent for office property in New York is pricey, though—the average asking rent in 2014 was $67.05 per square foot, the highest in the U.S., according to CBRE. While New York may not be the easiest place for tech companies to build sprawling campuses, the office properties in the city do offer an opportunity to transform workspaces into unique hubs where collaboration and ingenuity can thrive.

In 2014, CBRE partnered with Internet Week New York (IWNY) to create Tech Digs: NYC Edition, a four-part video series that offers an insider’s look into the most innovative tech offices in the city.
