Heyo is a social marketing platform for building and running online promotions such as sweepstakes, contests, giveaways, quizzes, and coupons. Businesses use Heyo's drag-and-drop campaign builder and landing pages to create interactive campaign apps that publish to the web, mobile, and social networks including Facebook, Instagram, and Twitter. It is used to grow email marketing lists, generate sales leads, acquire new customers, reward existing customers, and increase social followers, with templated promotion apps and a free trial. Heyo is a portfolio company of 500 Global and was acquired by Votigo, Inc. in January 2016, continuing to operate as a stand-alone self-serve brand.
