Data-Marketing Agency: Tracking, structuring, visualization, and AI to support your decision-making.
Data Détective is a full-stack data agency. We help outstanding small and medium-sized businesses and mid-market companies leverage 100% of their marketing data—from collection to decision-making—with a specialist at every stage of the data lifecycle. A company’s business performance is now directly linked to its ability to leverage its data. Yet most executives spend most of their time entering numbers into a spreadsheet rather than analyzing them. Without reliable data, every decision made based on intuition comes with a hidden cost. We work across the entire data value chain: Tracking and collection : GA4 and ad network setup, server-side tracking, GDPR compliance, and opt-in rate optimization; integration of offline conversions (CRM, ERP) to drive decisions based on actual ROI. Data engineering : centralization in a data warehouse, modeling, and pipelines to establish a single source of truth. Reporting and Analysis : Decision-support tools tailored by business function, specialized marketing analytics. Scaling : Applying AI to structured data to generate truly actionable insights and recommendations. Our beliefs : Reporting has value only insofar as it drives decision-making. Visualization is a convenience; the value lies in data collection and structuring. And without a structured context, no AI can produce actionable results. After working with over 100 advertisers and more than 20 agencies, our mission is clear: to reconcile your data, establish your truth, and empower you to make quick and accurate decisions. Data Détective is made up of specialists with a more business-oriented perspective than data analysts and a deeper understanding of data than marketing agencies. Want to leverage your data to improve your performance? Schedule a meeting with our CEO and our data strategist.
