Former AOL executive Jon Brod launched on Wednesday an app aimed at professionals who can send private messages that disappear once they are read. The new company Confide takes a page from the highly popular Snapchat, the mobile app embraced by teens that allows users to exchange fleeting photos and messages. “This is optimized for professionals and business people,” said Brod, who co-founded Confide with Yext co-founder Howard Lerman and entrepreneur Dan Sutera.
