Monitise Plc, a provider of mobile banking and payment systems, has hired a former Visa Inc executive to co-run the company as it pursues a sevenfold increase in users by 2018. Shares of Monitise rose more than 7 percent on Wednesday morning after the company announced the appointment of Elizabeth Buse as co-chief executive. Buse, 53, will work alongside Monitise’s founder and current chief executive, Alastair Lukies. “Her joining gives a lot of credibility to Monitise as a business and to their claim of gaining market share in the business in the U.S.,” said Ali Khwaja, analyst at Berenberg bank.
