We dive into your tracking so you don't have to

Web analytics auditing, fixing, and monitoring by subscription. Powered by advanced crawlers and AI. Founded by two senior analysts with 9 years of GA4 & GTM experience each.

Dive in

From surface
to signal

We scan every layer of your tracking stack, from the pixels your visitors see, down to the raw data flowing through your pipes, then surface what's broken and fix it.

Where automation meets AI

Our advanced crawler loads every page, fires every event, and maps your entire tracking setup. AI then analyzes the results and produces clear, actionable summaries of what's working and what's not.

iii. Tags & Tagging Plan

Every tag inventoried, then a full tagging plan generated

We map every tag firing on your site: Google, Meta, TikTok, LinkedIn. We flag what's misconfigured or missing, then generate a complete tagging plan so nothing falls through the cracks.

The data beneath the surface
