Retail Media Has a Trust Problem. NIQ and Unlimitail Just Built a Fix for It.

NIQ and Unlimitail announced a strategic collaboration on June 16, 2026 to address a gap that has persisted as retail media spending has scaled rapidly: brands are increasing their investment in retail media networks faster than their confidence that the measurement behind those networks can be trusted.

According to data cited in the announcement, 67% of CMOs plan to increase retail media spending in 2026, while only 53% believe current retail media networks provide adequate measurement and attribution capabilities.

The collaboration combines Unlimitail's retail media network, spanning 21 countries, 35 retailers, more than 120 retailer websites, and over 250 million loyalty cardholders, with NIQ's measurement, analytics, and consumer intelligence capabilities.

The explicit goal is to move advertisers beyond campaign-level metrics toward understanding the actual business impact of retail media investment, linking media exposure directly to verified sales outcomes rather than proxy engagement data, according to the press release.

"Retail media is becoming one of the most important growth engines for brands and retailers, but its future depends on trust, transparency, and measurable business outcomes," said Emilie Darolles, President of West Europe at NIQ. "Together with Unlimitail, we're helping create a more connected measurement ecosystem that enables marketers to move beyond assumptions and confidently demonstrate the impact of their investments."

How the Rollout Works

Unlimitail will integrate NIQ's measurement capabilities as a core component of its technology ecosystem, alongside a new data clean room environment that enables privacy-safe data collaboration and enhanced AdTech infrastructure, according to the press release.

Initial deployment begins with Carrefour operations across France, Spain, and Brazil, with pilot programs expected to launch in mid-2026 before expanding more broadly across Unlimitail's retailer network.

"Retail media has evolved from an emerging channel into a strategic pillar of modern marketing," said Alexis Marcombe, CEO of Unlimitail. "By integrating NIQ's trusted measurement capabilities into our ecosystem, we're enabling a new level of transparency and performance accountability that will benefit advertisers, retailers, and consumers alike."

The companies frame the collaboration as part of a broader industry shift toward unifying media, commerce, and consumer data, standardizing measurement across what has historically been a landscape of inconsistent, retailer-specific reporting standards that made cross-market campaign comparison difficult for advertisers operating at scale.
