What many were anticipating would be one of Internet Week New York's banner events will not get off the ground.

Dozens of startups had been invited to pitch their ideas on May 22 to an array of veteran entrepreneurs and investors, elevator-pitch style, while literally riding in elevators. And not just any elevators: These would be some of the newest and fastest elevators in New York City, in the Manhattan skyline's most iconic not-yet-open-to-the-public skyscraper--One World Trade Center.

This week, as the adjacent 9/11 museum opened its doors to a great deal of media and the public, the pitch contest was abruptly postponed until November 20. 

A publicist for the event, which is part of a series called the International Startup Festival's Elevator World Tour, said after conversations with the building's managers, the decision was made to postpone the pitch competition until construction on One World Trade Center is complete.

"Unfortunately, such an iconic location carries certain risks, and after lengthy discussion with the One World Trade Center management team, we have decided to postpone the event due to issues regarding the security of the building," the publicist wrote in an email.

The publicist did not respond to a request for further details.
