Suncorp has drawn a line under its overly ambitious plan to become the Amazon of financial services. The company plans instead to divert its tech expertise into piecing together a digital bank to cut costs and retain customers.The company used its annual results presentation yesterday to announce that the 'customer marketplace' - which was to combine Suncorp's customer platforms, customer experience and strategic innovation functions, along with third party products - will be superseded by a new 'Customer and Digital' function. Or, as acting CEO Steve Johnston put it: "The more aspirational elements of the marketplace component of the strategy, and the associated third-party revenues that were assumed to flow from those activities, have been too ambitious relative to where our business is at and the funds we have available to invest."Suncorp is also aligning its Australian contact centres, stores and intermediary distribution teams with its banking and insurance operations.As a result of these changes, Pip Marlow, CEO Customer Marketplace, has decided to leave the business at the end of this month. She was recruited from Microsoft Australia, where she had been managing director, in early 2017, by Suncorp's previous CEO, who resigned two months ago.Marlow was shown in Suncorp's annual report for FY 2018/19 as being paid just over A$2 million. The $802,000 Suncorp paid her in deferred bonuses as compensation for leaving Microsoft made her its second-highest paid executive in FY19 after Michael Cameron, who earned just over $5 million in salary and vested bonuses.Lisa Harrison has been named as Suncorp's new chief customer and digital officer. She was appointed to the senior leadership team in 2017 as chief program excellence officer and has been responsible for the delivery of the business improvement program, which Suncorp said has cut $280 million in costs from the group in FY 2018/19.One item that will be high on Harrison's agenda is to resolve the company's current strategy of running its legacy Hogan core banking software alongside its Oracle system. The next step - that is, to add the deposit and transaction module onto the Oracle core banking system - seems to be outside the risk appetite of the leadership team.Johnston told analysts during presentation of the group's results that the additional costs add up to "$10 or $11 million" but wants to see the system deployed "to a bank of scale" before making a decision on whether to deploy the extra Oracle module.
