NEW YORK, October 27, 2010 – NYSE Technologies, the world’s leading provider of end-to-end electronic trading solutions and a unit of NYSE Euronext (NYX), today announced a strategic alliance with technology advisory firm, CSTK InVenture.   A joint venture between KLG Advisors and CS Technology, CSTK InVenture brings together a range of expertise from enterprise infrastructure to real estate, creating a powerful paradigm shift in the traditional trading market environment.

“This engagement with CSTK InVenture aligns with our intent to aggregate thought leadership in the low-latency trading and infrastructure spaces while providing even greater deployment of choices for our clients,” said Stanley Young, CEO of NYSE Technologies. “Our collective combination of deep experience and business-specific insight produces a tightly integrated approach that directly complements our markets, infrastructure, and real estate assets further strengthening our position as a premier provider of institutional financial services technology.”

Origin of the NYSE Technologies/CSTK InVenture Alliance
CSTK InVenture took form in 2008 when NYSE Euronext engaged KLG Advisors and CS Technology to provide advisory services to help develop, integrate, and support some of its business, technology and real estate transformation, including NYSE Euronext’s new global liquidity centers.   As a result of the original collaboration, NYSE Technologies and CSTK InVenture formalized a strategic alliance to create an innovative business model that leverages NYSE Technologies’ best-in-class electronic trading solutions with CSTK InVenture’s advisory services to generate unique business value and bottom-line enhancements for other world-class financial organizations.

“The insights gained through our liquidity center initiative revealed opportunities to help unlock the business value and revenue potential inherent in the NYSE Technologies platform as well as the physical and technical assets of other business and trading partners,” Mr. Young said.

JP Rosato, CEO of CS Technology said, “Working with NYSE Technologies, CSTK InVenture has developed a comprehensive diagnostic assessment that provides transparency within our client’s environments and enables them to make fully informed investment decisions to drive high performance and outsized returns.”

Adds Doane Kelly, President of KLG Advisors, “By leveraging the synergies between technology and real estate, the strategic alliance between CSTK InVenture and NYSE Technologies will help clients identify and capitalize on potential business deals and revenue-generating opportunities that align with quantifiable financial goals.”
