Bill McCloskey, President and CEO

Mr. McCloskey is among the more influential thought leaders in the field of interactive marketing. He was named one of online advertising's 50 most influential people by Media Magazine in 2004 and one of the 100 people to know by B2B Magazine in 2003.

Since 2003, Mr. McCloskey has authored a weekly column called The Email Insider that is read by more than 40,000 marketers worldwide. He frequently speaks at major trade conferences around the world and is jurist for some of the top email campaign and creative awards at these and other events.

Prior to Email Data Source, Mr. McCloskey founded and ran Emerging Interest, the leading evaluator of online advertising technologies for advertising agencies and marketers as well as The Rich Media SIG, a non-profit organization dedicated to educating agencies and marketers on emerging marketing technologies.

As Director of Business Development at Comet Systems, Mr. McCloskey led the team that developed the business model and relationships around their contextual advertising products.

More recently, Mr. McCloskey created The One Hundred Club, a private, invitation-only email discussion group consisting of the most influential and important C-Level interactive marketers, publishers, analysts and technology vendors.

Both of these organizations maintain lengthy waiting lists for applicants.

Cullin Wible, Chief Technology Officer

Mr. Wible is an experienced technology entrepreneur with a proven history of successful product development. Over the past decade he has designed and managed the development of numerous technology products now in use commercially, while also managing infrastructure planning for these companies.

Prior to Email Data Source, Mr. Wible founded Algorim Technologies, a company focused on leveraging open source software to provide lower-cost enterprise technology solutions. Algorim developed enterprise solutions at a fraction of their anticipated cost. Many of these products are still sold and in use today.

Before founding Algorim, while a product manager for Comet Systems, Mr. Wible built and led a team of developers through the creation of a content-based contextual advertising platform that became the precursor to many other such platforms in use today. He was also the CTO of Vendquest, a real-time inventory information hub for the automotive industry. While there, he led a team of developers through a product revision that improved the product's response time seven-fold and decreased the infrastructure required to host and run it, effectively reinventing the company's technology in less than six months.
