Another executive switch at Yahoo (NSDQ: YHOO). The company has hired Raymond Stern as its SVP of business development and partnerships; Stern replaces five-year Yahoo veteran Jim Schinella, who Yahoo says has left the company for “personal reasons.” In a statement, a Yahoo spokeswoman says that Stern will be “focused on a key overall company strategy—partnerships and business development.” Prior to joining Yahoo, Stern was the CEO of digital delivery firm Presto Systems; he has also worked as the SVP of strategy and the chief marketing officer at Intuit. It’s the latest executive switch at Yahoo. In late October, the company hired former General Electric executive Andrew Siegel as VP of corporate development. Stern’s hiring was first reported earlier today by AllThingsD’s Kara Swisher.
