What UnNest Data Consulting does

UnNest Data Consulting is a Paris-based data and analytics consultancy founded in 2021, operating under the legal entity Unnest, Société par Actions Simplifiée (SAS), with its registered office in Clichy, France. The firm serves French and European small-to-medium enterprises, scale-ups, agencies, and large enterprises (including L'Oréal, ENGIE, PMU, Figaro, and ba&sh), providing end-to-end data project support across five service lines: Data Consulting & Strategy, Data Product Management & Governance, Tracking & Web Analytics, Data Platform Engineering, and Data Intelligence.

The firm's underlying technology stack spans the modern data ecosystem, including Google Cloud and AWS cloud platforms; data warehouses such as Snowflake and BigQuery; ELT/ETL tools including Airbyte, Fivetran, and dbt; analytics platforms such as GA4, Piano Analytics, Adobe Analytics, Matomo, and Amplitude; tag management via Google Tag Manager (including server-side); CDPs such as Segment and Tealium; and BI tools including Looker, Power BI, and Tableau. UnNest pairs this implementation expertise with structured training programs ("Nos formations") spanning 15+ tools, an Insights knowledge base, a Data4Marketing Slack community of 600+ members, and a free weekly "Clinique de l'Analytics" consultation service.

Commercially, UnNest operates a professional services model, generating revenue through project-based consulting engagements and instructor-led training, with pricing handled on a quote basis rather than published rates. Go-to-market combines sales-led direct engagement with a community-led motion anchored in the Data4Marketing Slack group. In December 2025, the firm was acquired by Havas, the global media and communications group, to bolster Havas Media Network's technology and data capabilities; UnNest continues to operate under its existing brand as a Havas-owned entity.
