Kantar Media Rebrands as Fifty5Blue Post-PE Carve-Out

The deal, which closed in August 2025, spun Kantar Media out from the broader Kantar research business, where it served as the company’s media measurement arm. As part of the transaction, it was required to adopt a new brand identity within two years.

Now as Fifty5Blue, established products—including Ibope, the primary TV ratings currency in Latin America; TGI, its global consumer profiling and targeting survey; and TechEdge, the software platform used to analyze and visualize audience data—will remain central to the portfolio.

Global CEO Patrick Béhar said the name is intended to signal transparency and independence in an increasingly complex media landscape, with “55” carrying layered references to the company’s history and future ambitions.

“Blue is about clarity,” Béhar told ADWEEK. “In a world full of noise and no shortage of data, we believe clarity is the real differentiator.”

The company employs approximately 4,500 people globally, having retained its full workforce post-sale. It will remain headquartered in London.

From panels to intelligence

Long known for providing the audience data that underpins billions of dollars in advertising transactions, Kantar Media now aims to expand beyond traditional ratings into attribution and outcomes measurement.

That shift comes as artificial intelligence reshapes media planning and measurement, creating opportunities to use both directly observed panel data and modeled data. As Fifty5Blue, the company aims to combine its legacy panels with large-scale first-party data to expand what it can measure.

Béhar maintained that media currency still requires a foundation in directly observed human behavior to avoid bias and preserve transparency, and that panels serve as a benchmark to reconcile data across streaming, social, and broadcast.

“You need a direct observation somewhere,” he said. “The panel is your safeguard and your life insurance.”

But while AI will not replace panel-based measurement, it will improve efficiency and deepen the analysis teams can do on that data, he added.

Investment and leadership changes

Since its sale, Fifty5Blue has reshaped its leadership team, hiring Toni Petra from Nielsen as chief operations and technology officer; Nicole Gileadi from Google as chief strategy officer and managing director of North America; and former McKinsey executives to lead strategy and transformation efforts.

The company has also increased investment in its technology infrastructure and cross-media measurement capabilities, Béhar said.

With private equity backing, Béhar said Fifty5Blue can invest more directly without competing with other divisions for capital. He pushed back on the idea that private equity ownership creates short-term pressure.

“I think there’s a bit of a myth that private equity is harsher, more difficult, and more short term,” he said. “We have embraced the freedom to move faster, sharpen our focus, and invest for the long-term.”
