Former Tinder marketing Vice President Whitney Wolfe is suing the popular dating-app company for sexual harassment and discrimination, making it the latest technology business to face challenges over its treatment of women.

Wolfe's lawsuit, filed Monday, listed a series of alleged incidents of harassment over roughly 18 months starting in late 2012. Among the allegations: that Chief Executive Officer Sean Rad and the company's chief marketing officer, Justin Mateen, removed her title as co-founder because of her gender; and that Mateen publicly insulted her, including calling her a whore at a company party, while Rad ignored her complaints.
