BI (business intelligence) vendor MicroStrategy is getting out of the contact center software business, having sold off its Angel subsidiary to Genesys for roughly $110 million in cash. The deal is expected to close in March. Angel offers an array of cloud-based, self-service contact center products, with interactive voice response, chat and other capabilities. Angel has developed a series of customer service applications specialized for various industries, such as banking and health care, according to a statement released Tuesday.
