Ep.94 | Building a castle on sand: Modern's Adrianne Haynes-Samuel on why marketing attribution keeps breaking
Consolidating the MarTech stack was supposed to produce one clear reporting picture. It did not. Adrianne Haynes-Samuel, digital and technology principal at Modern, argues the tooling is rarely the problem. The data model underneath it is. It goes out of date as service offerings change and CRM fields get edited. Taryn Breetzke speaks with Adrianne about Halo IQ, the product she heads up. It sits on top of an existing stack, normalises CRM data and maps every interaction on an account. She explains why around half of CMOs distrust the attribution model they already have. The second half turns to the dark funnel. When buyers research inside AI platforms first, first touch stops being measurable. Adrianne argues for measuring AI references instead. Four takeaways Attribution assumes consistent data. Change a CRM field and the two year view breaks. Governance comes before tooling. Frameworks produce the attribution model, not the reverse. Lead counts do not answer what boards actually want to discuss. Most AI projects are automation projects. The foundational problems sit underneath.
