Coupa Software, a business spend management company, has acquired Yapta, a travel price optimization firm. According to an announcement, the acquisition enables Coupa to deliver more value across spend management by empowering companies to achieve greater savings in a significant spend category, travel and expense. Based in Seattle, Yapta monitors airfare and hotel prices in real time and sends instant savings alerts when prices drop. Rob Bernshteyn, CEO of Coupa, said business travel, which accounts for more than $1 trillion of spend per year, is often one of the spend areas within a business with the least visibility and control. He said, "Yapta offers greater transparency into travel spend, helping businesses get the most value from their travel planning.” Coupa says it offers a comprehensive, cloud-based business spend management platform that has connected hundreds of organizations with more than four million suppliers globally.
