March 11 (Reuters) - Bumble on Wednesday posted fourth-quarter revenue above estimates, as the dating app operator began to see early benefits from a broad turnaround plan, sending its shares up about 12% in extended trading.

Bumble has been undergoing a strategic overhaul since founder Whitney Wolfe Herd returned as CEO about a year ago, pushing for product improvements and new AI-enabled features designed to better appeal to younger daters and counter stiff competition in a saturated market.

Total paying users for the reported quarter decreased 20.5% to 3.3 million.

The company posted quarterly revenue of $224.2 million, compared with analysts' estimates of $221.3 million, according to data compiled by LSEG.
