Feb 10 (Reuters) - Bumble Inc, a dating app operator backed by buyout firm Blackstone Group Inc, sold shares in its initial public offering (IPO) on Wednesday at $43 apiece above its target range, to raise $2.2 billion The IPO gave the Austin, Texas-based company a market capitalization of more than $7 billion. Bumble had aimed to sell 45 million shares at a target price range $37-$39 after previously upsizing the share offering from 34.5 million shares at a band of $28-$30. Some dating apps like Bumble have flourished even under COVID-19-related social distancing, as people who stay at home turn to instant messaging to seek romance. Bumble, which also owns the Badoo dating app, said it expects to record up to $541.5 million in revenue between January and December 2020, up 11% from the prior year driven by growth in paying customers. The company had 42 million monthly active users as of the end of September, out of which 2.5 million were paying users, up 22% from the prior year. It had $900 million in debt. Bumble, whose eponymous dating app allows women to initiate introductions, was founded in 2014 by Whitney Wolfe Herd after an acrimonious departure from rival app Tinder, which she had co-founded. Wolfe Herd, 31, had sued Tinder alleging that her co-founders subjected her to sexual harassment. Tinder parent Match Group Inc, which denied the allegations, paid about $1 million to settle the dispute. A court fight, however, broke out in 2018 after Bumble rejected a $450 million acquisition offer from Match. Match had filed a lawsuit against Bumble alleging intellectual property infringement. But Bumble counter-sued two weeks later accusing Match of fraud and trade secrets theft. Both lawsuits were later dropped that same year. In 2019, Blackstone paid about $3 billion to acquire majority stake in MagicLab, which owned the Bumble and Badoo apps at the time, from founder Andrey Andreev. Wolfe Herd was named Bumble’s chief executive officer after the deal. Bumble’s shares are due to begin trading on the Nasdaq under the symbol “BMBL.” Goldman Sachs and Citigroup are the lead underwriters for the offering.
