I have known the Pierian team in London for over 3-years as 'masters of mar-tech'. During late 2022, we needed a trusted partner to work with our agile digital chapters to evolve and maintain our 'data-layer' across multiple website and mobile app channels in Greece. Pierian stepped in to set-up an agile process, mobilise teams and managed our Tealium deployment to enable analytics, attribution, Personalisation and media use cases over a 12-month engagement supporting brand, paid media, eCommerce and mobile marketing.
