About the COOL company
The COOL company is a global leader in AI-powered advertising technology, helping brands, agencies, and publishers simplify advertising and amplify performance.
Powered by COOL AI, our intelligent platform unifies creative generation, media activation, optimization, and attribution into one continuously learning system. Instead of relying on fragmented tools and manual campaign management, COOL AI executes thousands of real-time micro-optimizations across search, social, display, video, and connected TV—helping customers launch faster, optimize continuously, and achieve stronger business outcomes.
Our innovation and growth have earned industry-wide recognition, including being named a 7-time recipient of the Inc. 5000 list of America's Fastest-Growing Private Companies, a 2-time Deloitte Technology Fast 500 honoree, recognized on Crain's New York Fast 50, honored by the Digiday Media Awards for helping modernize digital media, and named one of Adweek's Top 10 Fastest Growing Solution Providers globally.
We're building the future of advertising, where every signal becomes intelligence and every optimization drives performance. As we continue to grow globally, we're looking for curious, ambitious people who want to work with cutting-edge AI technology, solve complex challenges, and help redefine what's possible in modern advertising.
