Today we are "a face-to-face" business Tyro CEO Jost Stollman told Banking Day.Incredibly, the most prospective territory for a business of Tyro's stripes, digital commerce, is off limits, a legacy of the handicap of MasterCard and Visa capital rules from an earlier era."We haven't ventured into online," Stollman said.Instead, there is a "focus on depth and integration with existing merchants."Online acquisition is in the pipeline," Stollman assured Banking Day."I only have 150 engineers. We need to dramatically develop our ability to develop new products," he said."We built our own core banking platform and have launched it. We now need to develop the products. This is our core competency.""With any third party we would not be able to innovate," he said.Has Tyro an IPO on its mind? "We shall see," Stollman said. "The regulator would look kindly on a broad shareholder base and access to capital markets."
