The El Segundo-based Prodege acquired its fourth company in the last 13 months as it seeks to dominate in the digital rewards program space and strengthen its consumer analytics business.

The owner of consumer rewards site Swagbucks and MyPoints picked up Upromise Inc, an education-saving rewards business owned by Sallie Mae, giving it a foray into credit cards and helping the company build its consumer data business. Terms of the deal weren't released.
