CheckFree to Purchase Corillian in Bid to Expand Offerings to Banks CheckFree/Corillian deal is just one more example of consolidation in bank tech space, say experts. Atlanta-based e-commerce services provider CheckFree last week announced plans to acquire online banking solutions company Corillian (Portland, Ore.) in a deal worth about $245 million dollars. The acquisition will bring together Corillian’s online banking platform and complementary suite of financial applications, and CheckFree’s electronic billing and payment, and online transaction services. According to Steve Olsen, CheckFree’s COO, the union will help the company reach further into the online channel as it attempts to expand its client relationships and help those banks it serves do the same.
