As Senior Vice President of Account Management for Media and Data Collaboration Services at Environics Analytics (EA), Andrew Tziatis leads the team that manages and grows EA's relationships with its key media, agency, advertiser, platform and data collaboration clients. He works with clients to match EA's data, audience, analytics and clean room capabilities to what they need, and oversees the platform and activation partnerships that get EA's audiences into market.
Andrew joined EA in June 2026 after 20 years within media agencies, nearly 16 of them at WPP Media. Most recently, he was President, Data, Tech and Analytics, leading Data Strategy, Advanced Analytics, Data Visualization and Product teams and practices. His earlier roles covered data and audience strategy, client strategy and account management, and traditional planning and buying, so he has worked every part of the media cycle and seen how data, used well, leads to more useful discussions and better decisions.
