Yipes, a national provider of bandwidth, owns fiber rings in metropolitan areas and builds spurs to buildings, where switches are installed providing Internet access. After that, the company tries to sell services to tenants who will be able to pick among four or five different providers who have done the same as Yipes.

Yipes now holds contracts to service more than 3500 buildings in 21 markets across the country. It did so by acquiring in bankruptcy the building service rights held by Broadband Office. Since that time, Yipes has cut separate deals with nine of the largest real estate owners and managers in the country, securing access to hundreds of millions of sf nationwide.

The company has service agreements with Shorenstein, Equity Office Properties, CarrAmerica and 17 other real estate companies. Yipes' portfolio includes access to some of the better known properties in the United States including the Bank of America Center in San Francisco, John Hancock Center and Prudential Plaza in Chicago and First Union Financial Center in Miami.

Yipes' other clients include Fortune 1000 companies, financial institutions, ISPs and ASPs, Web-based businesses, software developers, law firms, major medical facilities, universities, school districts and government agencies. Yipes has received $291 million in equity funding from more than 30 investors including Norwest Venture Partners, New Enterprise Associates, The Sprout Group/CSFB, Charter Growth Capital, JP Morgan Partners, BancBoston Capital, Soros Private Equity Partners, Focus Capital and Intel Capital.
