This was me on my last day at Farfetch.

We used a big consultancy (over £500k/year!) to determine marketing incrementality & measure brand spend. I sat in those meetings, looking at the results and thought: “this is cool but why should it only be available to companies with massive budgets?”

That question stuck with me and led me to build Day1Data. We make this kind of marketing insight available to companies like Healf, PerfectTed & WorldRemit, who have achieved 20x marketing ROI from working with us.
