The companies "made contractual promises to recruit and retain the men and women who built Tinder" but then "lied, bullied, and violated their contractual duties, stealing billions of dollars,"said attorney Orin Snyder, who filed the suit on behalf of Tinder co-founders Jonathan Badeen, Justin Mateen, Sean Rad and others from its startup days.

The suit names IAC and Match as defendants, accusing the companies of breach of contract and called for at least $2 billion in compensation along with punitive damages.
