Looking for instant answers? Acuity (formerly iChat) makes software that lets call center representatives chat with customers over the Internet and respond instantaneously to questions via the same technology used to facilitate chat rooms. Its WebCenter Enterprise manages Internet-based customer service sessions by offering self-help, queuing calls to be handled by representatives, and responding to routine questions by e-mail. Founded in 1995, the company initially focused on consumer chat programs, but it has sold off its ichat product line and redesigned its technology for corporate customer service use. Customers include Lucent and drugstore.com. Acuity is a subsidiary of software maker Quintus Corporation.
