BlackBerry acquired Tungle and Gist awhile back to upgrade the calendar and contacts system in BlackBerry 10. Now that those acquisitions have started to pay dividends it seems like they have lost the founders of both those companies. The WSJ is reporting that TA McCann, VP in charge of Social Networks, left BlackBerry two weeks ago. He was head of BlackBerry Messenger, Facebook, Twitter, and LinkedIn apps. Marc Gringas, founder of Tungle, also left in recent weeks and he was in charge of the contacts and calendar apps along with the HUB.
Its a shame to see them go but hopefully BlackBerry has some replacements lined up. Rumors have it that these execs either left because they “simply had it” with BlackBerry struggling or due to the “entrepreneurial itch” of wanting to start another company.
