Steve Berkowitz, Lumos Labs' new CEO, oversaw the $1.85 billion sale of Ask Jeeves in 2005.
The company behind popular "brain game" app Lumosity has a new CEO, and he's no dummy. Although Steve Berkowitz, the incoming leader of Lumos Labs, is best known for overseeing the growth of the For Dummies book series in the 1990s, he's also experienced in scaling tech companies and steering them toward large exits. Berkowitz will replace Kunal Sarkar, the company's co-founder and current CEO, who will become Lumos Labs' new chairman of the board.
