Houston-based WhiteFence, a comparison-shopping Web site for residential utilities and other services, announced Monday that it is providing realtors with a condensed version of WhiteFence.com. Called the Home Services Widget, WhiteFence explained that the new offering enables real estate Web sites to better cater to their clients during the relocation process. WhiteFence said the Home Services Widget is available for download at its web site. Once added to a Web site, WhiteFence noted, the widget will allow users to browse and compare landline telephone, electricity, cable, high-speed Internet and other services. WhiteFence is a privately held company backed by Adams Street Partners and the Internet Capital Group.
