Bellevue, Wash. and Helsinki, Finland -- Onyx Software Corporation (Nasdaq: ONXS), a global supplier of enterprise-wide, customer-centric e-business applications and TietoEnator, Scandinavia's largest IT company today announced a strategic alliance to provide Onyx's e-business solutions to companies across Scandinavia. The announcement was made at a press conference in Helsinki today where Onyx Software President & CEO Brent Frei and TietoEnator Managing Director Tero Ansio addressed a crowd of journalists. The event will be followed by a conference Thursday attended by more than 1,000 TietoEnator customers.

"TietoEnator's $1.2 billion revenue base and 10,000 employees provide ready customers and the ability to support them," said Onyx Software President & CEO Brent Frei. "TietoEnator's ability to deliver complex enterprise applications, country knowledge and vertical market expertise will support our plans for rapid expansion in Scandinavia."

"The importance of modern customer relationship management is increasing all the time, particularly in the direct, one-to-one environment of e-business," said Tero Ansio, Managing Director of TietoEnator Applications. "The addition of Onyx's relationship management systems to our own offerings means we can now offer a full range of e-business applications to our clients, covering the management of all their resources - financial, employee and customer. We selected Onyx as our partner because we share a similar business philosophy, based on excellent customer service, real professionalism and quality products which are both fast to deploy and easy to use. I have no doubt that our partnership with Onyx marks the beginning of a revolution in the way e-business is done in Finland."
