SurveyMonkey will add two new members to its board of directors, including Facebook's chief operating officer, Sheryl Sandberg. Sandberg is the widow of David Goldberg, who was CEO at SurveyMonkey from 2009 until he died in an accident while exercising in May. The Palo Alto, California, company said Monday its other new director is David Ebersman, the CEO of Lyra Health and former chief financial officer at Facebook. SurveyMonkey, which operates an online survey platform, also said Zander Lurie, its acting executive chairman, will take on the role on a permanent basis.
