Dating app Bumble is axing almost a third of its workforce, as it struggles to grow and investors sour on its prospects.

In a note to staff, chief executive Whitney Wolfe Herd said she was responding to pressures facing the company, as the dating industry faces an "inflection point".

"We need to take decisive action to restructure to build a company that's resilient, intentional, and ready for the next decade," she said.

Founder Ms Wolfe Herd stepped down as boss of the firm last year, but returned in March in a bid to turn around its prospects.

Bumble, which also owns Badoo, made its name as an app on which women were responsible for initiating contact.
