Our fifth edition of The MadTech Podcast Special explores the emergence and power of the 'private garden', a data model which involves focusing on logged-in users to gain the ability to offer more relevant audience segments to buyers.

In this episode, Matt May, senior biddable manager at Three; Phil Raby, GM UK at Mediarithmics; and Danny Spears, COO of The Ozone Project, join ExchangeWire's Rachel Smith to discuss what a private garden is, and what the model can offer brands and publishers.
