Adexchanges and real time bidding deeply change the way we access all types of media and data in real time. Combining the two can strongly improve the efficiency of the media plans that we manage across all media (Display, Mobile, Video, Radio, OOH, etc.). As audience planning replaces media planning, Affiperf allows real time optimisation and audience targeting for performance and branding purposes.

Affiperf is Havas's global trading desk operating in the programmatic buying area. We offer a global/local solution by selecting and using the most appropriate and efficient technologies, data and media providers for each client in every market.

Our offices in Paris, New York, London, Madrid, Mexico City and Hong Kong operate locally. The Affiperf Factory based in Paris manages campaigns globally for 50+ other countries.



Socialyse harnesses data to analyse human behaviour and measure outcomes.

Social media has changed marketing forever and is increasingly changing how brands do business. Social is complex and cannot be planned in a vacuum. Social Media is just another way for brands to reach people and should never be planned, implemented or evaluated in isolation from other communications activity. The Socialyse team believes that a joined up approach is the only way to get the most from any social media activity.

Social marketing specialists need to understand how social media can work for brands through all their customer touch points. It could be helping a brand to start from scratch or make existing social activities work harder and smarter; whatever the need. It has a broad range of capabilities that operate across paid, earned and owned media spaces.

At Socialyse, we offer a variety of skills and disciplines and our expertise includes: Social Media Strategy, Community Management, Conversation Intelligence, Social Analysis/Insight, Content Creation, Social SEO, Mobile Marketing, Blogger Outreach.
