Greg Hammermaster, who led Sage Payment Solutions for the last five years, has left the company. Christine Scappa, a 14-year Sage veteran led a briefing this week as acting president of the group. Her LinkedIn page shows her as SVP of Sage Payment Solutions while Hammermaster’s does not reflect a change in the position he held from October 2008. However, Sage public relations confirmed that he "left Sage a few weeks ago."
