The pain

The SaaS team had HubSpot, Google Tag Manager, ad accounts on three platforms, and several lead capture forms across the website. Attribution was broken.

Marketing thought leads came from ads. Sales thought they came from organic. Nobody could prove which campaigns paid back.

The founder needed a RevOps system that pulled clean attribution end to end, automated routing into HubSpot, and gave the team a dashboard they could trust.

What I built

n8n attribution engine

Captures UTMs at first touch and persists them through every form submit.

HubSpot schema

Documented property mapping with a single source of truth for every field.

UTM normalizer

Cleans inconsistent campaign tagging from the ad platforms.

Meta CAPI

Server-side conversion sending to recover events lost to iOS privacy.

GTM tag hygiene

Rewrite to remove duplicate firings.

Lead routing

Real-time into HubSpot with assignment rules by company size and segment.

Looker Studio dashboard

First-touch attribution, lead source, MQL conversion, pipeline by source.
