The chief executive of Tinder has left the dating app after less than a year after the market value of its parent company plunged by more than a fifth following reporting disappointing results. The departure of Renate Nyborg was one of a number of management changes announced by the $20bn Match Group, which owns dating brands including Hinge, Tinder and Match.com. Its share price plunged by more than 20% on Tuesday after missing Wall Street second-quarter expectations and issuing weaker-than-expected guidance. "Today we are announcing the departure of Tinder chief executive Renate Nyborg, and I have made some changes to the management team and structure that I am confident will help deliver Tinder's full potential," said Bernard Kim, the chief executive of Match Group, in a letter to shareholders. "We have not been able to realise the monetisation successes that we typically deliver. Tinder's current revenue growth expectations for the second half of the year are below our original expectations as a result of disappointing execution on several optimisations and new product initiatives."
