A global authority in audience measurement and media analytics — 100+ countries

NielsenIQ is a global authority in audience measurement and media analytics, empowering clients to understand what people watch, listen to, and buy. With operations in more than 100 countries, NielsenIQ blends data science and technology to deliver precise, actionable insights for decision-makers across every major industry.

At NielsenIQ's scale, data harmonisation is the foundation of everything. Clients across FMCG, media, and retail depend on outputs that are accurate, consistent, and fast — regardless of which country the data originates from.

Harmonising data from hundreds of sources — manually, across 100+ countries

NielsenIQ faced a fundamental data operations challenge: insights depended on harmonising data from multiple sources simultaneously — internal databases, third-party data providers, and client feeds — each with their own formats, schemas, and update schedules.

The manual processes involved were time-consuming and error-prone. Report generation was delayed. Accuracy was inconsistent. And as the volume of data grew across more countries and clients, the gap between what the team could deliver manually and what was actually needed kept widening.

Automated harmonisation pipelines — scalable across every source, every country

Mammoth gave NielsenIQ the infrastructure to automate data harmonisation at scale — without rebuilding their tech stack:
