BigBrain aims to bring live mobile trivia back to glory If you ask Nik Bonaddio why he wanted to build a new mobile trivia app, his answer is simple. “In my life, I’ve got very few true passions: I love trivia and I love sports,” Bonaddio told me. “I’ve already started a sports company, so I’ve got to start a trivia company.” And today, after a period of beta testing, Bonaddio is launching BigBrain. He’s also announcing that the startup has raised $4.5 million in seed funding from FirstRound Capital, Box Group, Ludlow Ventures, Golden Ventures and others.
