CHICAGO — IRI says it has reached a long-term agreement with Kroger Co. to be the supermarket chain’s preferred partner for market measurement services.

These services will provide Kroger and its supplier partners a common view of their business performance compared to the rest of the market, according to IRI, which said that its Liquid Data technology platform and extensive product movement and causal data — which includes weather, gas and macroeconomic factors — will help Kroger and its suppliers collaborate more easily and make better decisions to benefit customers.

“IRI and Kroger are at the forefront of the shifting landscape by providing better market measurement data and industry-leading technology to create highly personalized consumer marketing to drive growth,” IRI president and chief executive officer Andrew Appel said in a statement announcing the agreement.

“In everything we do and every decision we make, we put our customers first,” said Kroger executive vice president of merchandising Mike Donnelly. “Our relationship with IRI is another step in this direction. We believe IRI has the best tools and technology to allow both Kroger and our suppliers to access better market insights, helping us create even better experiences for every customer.”
