StackAdapt, a Canadian ad platform that started out in programmatic buying, added Shopify President Harley Finkelstein as a strategic advisor. Finkelstein, who joined Shopify in 2010 and served as its COO before becoming president, will counsel StackAdapt’s leadership on international expansion, product strategy, and building the company. StackAdapt is pushing into AI tools that let marketers plan, run, and measure campaigns across channels, and it’s also one of the ad tech partners OpenAI named in May to help advertisers buy ads in ChatGPT.
