Growth breaks when the numbers can't be trusted. We set up clean GA4, GTM, and Shopify pixel tracking with a solid event taxonomy and attribution foundation, so you can see what's working and where revenue leaks. On top of that, we use Amplitude to turn the data into real insight - funnels, drop-off, and retention that show not just what happened, but why.
