Our take
The Cool Company, formerly Insticator, delivers AI-powered advertising solutions for automation, campaign activation, performance intelligence and more. It helps brands, agencies and publishers to harness AI and first-party data to unlock the true potential of their campaigns.
Before this solution, almost 80% of publishers lacked the means to collect this valuable data - making The Cool Company a game-changer in the market. It makes it far more simple for users to boost engagement and ad revenue, and stands out as a strong option for businesses that want to measure and optimize these factors.
