firstlight x Worldpanel by Numerator

firstlight has been appointed as the new retained corporate agency for Worldpanel by Numerator (formerly Kantar) across the UK and Ireland. The change in agency partner follows Worldpanel’s integration with Numerator in 2025.

Worldpanel provides currency-grade consumer data representing nearly 6 billion consumers in over 50 markets, offering brands a multi-dimensional view of how people think, shop and consume. Its monthly Grocery Market Share report, detailing supermarket sales and shopping behaviours is a leading indicator of grocery performance in the UK and Ireland.

firstlight has been tasked with protecting the provenance of the monthly Grocery Market Share report, while delivering a more nimble and comprehensive press office programme to showcase the variety of data that Worldpanel provides, offering brands new opportunities to set strategies and drive business impact.

Beulah Neelmeyer, Marketing Director UKI said “Worldpanel’s role in the market is built on trust, from high-profile benchmarks like Grocery Market Share to the wider consumer behaviour insights that sit behind them. As we move into a new chapter as part of Numerator, we wanted a partner who understands both the responsibility and the opportunity that brings. firstlight’s experience, credibility and people, make them that partner.”

Paul Davies, CEO, firstlight said: “It’s brilliant to be working with such an iconic and trusted brand as Worldpanel and we can’t wait to bring its unrivalled consumer insights to life.”

This appointment comes as the business continues to expand its client roster, with 2025 wins including Legora and Specsavers.
