We look forward to building on the success we have achieved together and supporting their future growth across both online and retail channels.”
José Félix Herreros, Country Manager at Gran Madrid, said, “Renewing our partnership with Altenar reflects the success of our collaboration to date. Their technology, product innovation, and understanding of regulated markets have consistently helped us strengthen our sportsbook offering and meet the expectations of our customers.”
