UXC announced a partnership with ServiceNow in August as part of a growth strategy. Company officials said bringing Keystone under the UXC umbrella expands UXC's cloud-based solutions capabilities and increases its subscription-based annuity revenue.
Keystone CEO Dion Williams will report to UXC Managing Director Cris Nicolli, and the business will be branded UXC Keystone.
UXC managing director Cris Nicolli said "The acquisition of Keystone and the partnership with ServiceNow is very much part of the UXC strategic direction and is an exciting key growth opportunity for UXC."
"We see the high growth cloud-based IT Service Automation market, coupled with our strong ITSM experience in Australia and South East Asia, as ideal platforms to combine with Keystone.
"The expansion is also a compelling opportunity for a strong return on our investment and furthering our strategy of building our cloud services leadership."
Mr Williams and his fellow Keystone directors Paul Heath and Neil McKinnon will remain with the company.
