“As a leading provider of consumer finance and mortgage origination products and services, GHR will bring one of the most proven technology and market-leading solutions to our clients,” said Frank R. Martire, Metavante president and chief executive officer. “GHR serves many of the largest U.S. financial institutions and has focused on the top-100 bank market, which is important to Metavante.  We believe that the acquisition of the GHR Systems’ lending solutions platform will be perceived by our clients of all asset sizes as a valued addition to our technology offerings.”

Since its establishment in 1985, GHR’s mission has been to make the origination process easier for all parties involved – borrowers, lenders, manufacturers, vendors, brokers and processors – by supplying technology that provides faster and better information.

“Our mission has always been to provide our customers with the maximum of operating efficiency through the most complete and automated systems,” said GHR President Cyrus Brinn. “Joining Metavante will help us to better serve our clients with a broader array of financial services technology products.”

The GHR management team, led by Cyrus Brinn and Allan Redstone, will continue operating the business and become part of the Metavante Financial Solutions Group headed by Paul Danola, president and chief operating officer, Metavante Financial Solutions Group.

“By providing automation technology and services for residential mortgages that includes end-to-end origination from point of sale through underwriting, processing, closing, and documentation, we will now be able to deliver a premier, mortgage loan origination solution to our clients,” said Danola.
