In 2008, performance marketing was becoming increasingly fragmented. Ad networks were taking credit for conversions they didn’t fully drive, and most agencies were optimizing media against network-reported numbers and calling it performance. We didn’t trust those numbers. So we created our own measurement layer. What began as internal infrastructure evolved into Atrilyx — built on patented attribution technology, powered by Ai that connects channels, devices, and conversions into one reconciled source of truth. Every media decision we make runs through it. Every client engagement benefits from it. Nearly two decades and more than $1B in managed media decisions later, the problem still exists. The networks still grade their own homework. We still don’t let them.
