IEX TO MOVE NEW YORK OFFICE TO 4 WORLD TRADE CENTER
NEW YORK, Nov. 19, 2014 – Silverstein Properties announced today that IEX, a start-up stock market
dedicated to institutionalizing fairness through technology, and the subject of Michael Lewis’ book, Flash
Boys, has signed a 7-year, 13,000 square foot (1,208 square meter) lease at 4 World Trade Center. The
company expects to move to the 44th floor of 4 World Trade Center in April 2015.
“I am delighted to welcome IEX to 4 World Trade Center, and I look forward to watching this dynamic
young company as it continues to transform itself into a major national exchange” said Larry A.
Silverstein, Chairman of Silverstein Properties. “The new World Trade Center is open for business and is
attracting great companies such as IEX because it features the best office space on top of the best mass
transit, in the heart of the world’s most dynamic live/work community.”
“We are inspired by the resilience and effort it takes to rebuild the World Trade Center, and we want to
support the neighborhood as it continues to thrive and redefine itself,” said Brad Katsuyama, CEO and
Co-Founder of IEX. “Like most start-ups, we initially signed short-term leases. But thanks to our recent
growth and the support of an extraordinary group of investors, we were able to sign a long-term lease
with Silverstein to establish IEX headquarters in downtown New York City. We launched IEX in Lower
Manhattan, so this is our way of staying true to what got us here.”
“IEX represents the best of Downtown’s past, present and future,” said Janno Lieber, President of World
Trade Center Properties. “While Lower Manhattan remains the historic home of the New York Stock
Exchange, the New York Mercantile Exchange and countless major banks, it is no longer your
grandfather’s Wall Street. Today, Downtown is the hub of New York’s 21st century innovation
economy. IEX, which is at the creative intersection of technology and finance, really highlights this
Lease negotiations for IEX were handled by a CBRE’s Rocco Laginestra and Rob Wizenberg. Jeremy
Moss, Director of World Trade Center Leasing for Silverstein Properties, and Camille McGratty, Vice
President of Leasing, led the negotiations for the landlord, together with the CBRE agency team including
Steve Siegel, Mary Ann Tighe, Adam Foster, Steve Eynon, Evan Haskell, Ken Meyerson and David
According to the Downtown Alliance, 511 firms have moved to Lower Manhattan since 2005, leasing a
total of 12.3 million square feet (1.14 million square meters). 226 of those companies have been in
creative or professional services, taking 51 percent of the space leased.
In its 2013 report, “Brain Gain,” the Downtown Alliance explained, “The high-value knowledge workers
who drive the region’s economy – the people companies want to hire – increasingly live within a 30minute commute of Lower Manhattan. Extensive residential development and dramatic neighborhood
revitalization in Manhattan, Brooklyn, and New Jersey’s Hudson River waterfront cities have attracted
huge numbers of young, educated people, workers in the professional and creative fields that drive leasing
in New York City – who prefer apartment living and shorter commutes via subway, PATH, ferry, bike
and foot to suburban life and lengthy commutes via heavy rail or car.”
