Core processing startup Corelation Inc. ended the year with its first three credit union customers running live on its new KeyStone system.

The San Diego firm said it also entered 2012 with five more credit unions committed to converting to the member-centric platform.

The three credit unions live on KeyStone are the $95 million Harbor FCU in Carson, Calif., the $191 million Cabrillo CU in San Diego and the $24 million Oregon Pioneer FCU in Portland, the company said.

“After years of creating and perfecting the technology, we are finally executing in bringing credit unions live onto the KeyStone platform,” said Corelation President Theresa Benavidez.

She said Corelation will be converting a $530 million and a $390 million credit union to the KeyStone platform and that two others are being converted as outsourced clients of Wescom Resources Group, the tech CUSO of Wescom Credit Union.

“To manage the growing responsibility, we continue to build our staff by adding very talented and qualified industry experts,” Benavidez said. “As our client base grows, we will continue to look for and hire the best talent available in the market.”
