Few industries have more to gain from digital technologies than financial services. After all, finance is a pure bits business, based on the flow of data through billions of transactions.To date, most digital efforts in banking, insurance and brokerage have been directed at developing an online presence with no clear picture of customer benefits, and so this has led to low returns. Customer acquisition costs often exceed online revenues, and, according to research by Mercer Management Consulting, technology spending does not directly affect shareholder value. The lesson here: Technology can enable a successful business but not drive it.The most innovative and successful financial services companies understand that distinction. In Europe, two financial firms stand out for their use of digital technology to improve customer relationships: Marschollek, Lautenschläger und Partner AG (MLP) in Germany and Bankinter in Spain.MLP offers made-to-measure financial advice and services. The firm targets young professionals just out of college, whom it reaches through career seminars and other special programs. In recent years, MLP has captured more than one-third of graduating students annually, building a customer base of engineers, lawyers and physicians whose average age is 33. Obviously, this bodes well for future revenue streams.I
