FORBES - After a $2.2B IPO last February, Bumble dating app founder and CEO Whitney Wolfe Herd is operating "business as usual". Shares on the Nasdaq sagged to $40 in the summer after debuting at $76. "I'm not obsessed with the stock," she said, "I'm obsessed with the customer, the team, the innovation we're planning for the future." "If you're trying to get to that next milestone, don't focus on the short-term. Stay married to the long-term vision," Wolfe Herd told the audience of Forbes 30 Under 30 list honorees.
