BLOOMBERG LAW - Sean Rad says Greg Blatt 'crossed the line' with arm grab. The way Match Group Chairman and CEO Greg Blatt tells it, he hadn't seen Tinder founder Sean Rad in years and, even though they were now on opposite sides of a multibillion-dollar trial, he wanted to say hello. The judge declined to allow Rad's lawyers to question Blatt about the encounter in front of jury, but he warned Blatt not to make further contact with the plaintiffs or their lawyers. The exchange is illustrative of the combative nature of the trial, which just entered its third week and is expected to continue through Dec. 3. On the stand Monday, Blatt denied trying to steer the $3B valuation, which he said was similar to the amount Wall Street analysts had estimated. Rad claims Tinder was actually worth $13B at the time.
