Context

A French HR-tech leader scaling fast had no data team, no warehouse, and dashboards built directly on source tools. User journeys were unreconciled and a large share of traffic was lost to ad-blockers. Constellations was brought in as the first data hire to build the practice end-to-end.

Scope & Deliverables

  • Practice Build: Built the data practice 0-to-1 — team, governance, and ways of working with business teams.
  • Tracking Stack: Internalized the full tracking stack, recovering traffic visibility blocked by ad-blockers.
  • Platform: Deployed an end-to-end data platform on AWS Redshift, covering ingestion, modeling, dashboarding and activation.
  • Team Growth: Developed the team from 0 to 5 across Analytics Engineering, Data Analysis and Data Engineering.
