Adtech startup Sortable acquired by U.S. rival

Waterloo Region adtech company Sortable has been acquired by a U.S. competitor looking to scale in the digital ad-management space. Arizona-based Freestar says that Sortable’s technology adds to the company’s existing suite of tools and products, which help content publishers, e-commerce sites and apps increase their revenue through “programmatic advertising” – the automated buying and selling of online advertising.
