Data architecture for
better decisions.
Tracking infrastructure, compliance audits, and production-ready code, all first-party, all GDPR-compliant. For companies that want to work with data, not just talk about it.
Why EARNST
Three things that set us apart.
What this means for you: No loss of control to subcontractors, legal protection through documented compliance, and a clear investment with measurable returns.
What this means for your campaigns: Fast adjustments without lengthy coordination loops, no data gaps from consent issues, and reliable conversion numbers for your optimisation.
What this means technically: Code reviews instead of black-box implementations, GTM configurations as infrastructure-as-code, and a consent integration that follows the specification.
We implement ourselves.
No slide decks, no outsourcing to subcontractors. The code comes from us. From concept to deployment.
GDPR is not an obstacle, it is a quality standard.
We work with data protection lawyers. Every setup is documented, auditable, and holds up under scrutiny.
Measurable results, not vague promises.
27% average ROAS uplift through server-side tracking. Lighthouse scores above 90. We deliver numbers, not adjectives.
