"It’s a “No brainer product, just download the update as soon as they arrive and performance is really good. I would like each product to work that way"

Arnaud Briche - CTO - Adyoulike


  • Adtech is complicated and Ad blocking and Ad fraud remain a challenge.
  • Exchange auctions happen within milliseconds, you need fast, accurate device data to enable decision making.
  • Without detailed device intelligence, you have very little information on your users and their devices.
  • If responsive only web design is applied, users may be served ads that don't fit their screen or simply don't appear therefore this results in a poor end-user experience and a wasted budget for advertisers.
  • Show you care for your advertisers and the end users by investing in device intelligence to enable delivery of server-side optimized content and inject some speed, accuracy, and ROI back into the process.
