I guess this wasn’t a match made in heaven. Match Group, and online dating company and it’s owner IAC/InterActiveCorp., filed a lawsuit on Tuesday, January 15th assuming Sean Rad, one of the founders of the popular dating app Tinder, of stealing company files and other proprietary information.

The lawsuit comes 6 months after Rad and the other Tinder co-founders sued IAC/InterActiveCorp, accusing the company of deflating Tinder’s valuation in order to avoid paying them for their work.

Now Match Group and IAC are hitting back with a $250 million lawsuit states that “Rad surreptitiously copied a large volume of documents belonging to his employers in order to advance his personal interests. Rad then violated his obligations to his employers by retaining those copies after his employment was terminated, again, so that he could use them for his personal gain.”

For his part, Rad is calling this a “desperate act of retaliation.”
