Client

Thermondo, a leader in sustainable heating solutions.

Objective

Thermondo wanted to optimise their tracking performance, improve GDPR compliance, and increase advertising efficiency — without losing the data quality their marketing decisions depended on. The project aimed to migrate their tracking to a server-side environment while using data science to raise data quality and recover the signal lost to cookie consent and fragmented sources.

What we did

Over a six-month engagement we delivered a comprehensive solution:

  1. Tracking migration — Moved their setup to a server-side environment with Google Tag Manager, removing the reliance on cookies and keeping visitor data in a secure server environment for GDPR compliance.
  2. Data-science-driven data quality — Applied our data-science know-how to clean, model and enrich the anonymised data: we reconnected fragmented events across sources, modelled the conversions lost to consent gaps, and built new joins between marketing, lead-funnel and CRM data for far broader coverage.
  3. Attribution & insight — Refined attribution rules on top of the higher-quality dataset for a clearer, more complete view of campaign performance and customer journeys.
  4. Advertising optimisation — Fed the cleaner, better-connected data back into the ad platforms to make campaigns measurably more efficient.
  5. Engineering collaboration — Worked closely with the in-house team to improve the lead form and integrate the new tracking with their lead funnel and Salesforce.

Results

  • +15% — Improvement in return on ad spend
  • 80% — Reduction in tracking loss
  • GDPR-compliant — Server-side data management with optimised privacy preferences

The solution integrated cleanly with Thermondo's existing systems and improved their lead-generation process end to end.
