Data Strategy Director at Havas Media Group

As Data Strategy Director for Group Data and Insight I continue to work on a number of interesting, significant and forward-thinking projects both for large clients and for the Havas Group itself - helping to develop, direct and future-proof the clients' and agency’s data strategy and development.

Recently this has allowed me to lead the data strategy roadmap for some large and progressive clients, whilst also looking at how the agency model has to adapt in this new world. This has led to some interesting client and agency consultancy work looking at how Havas Media will approach the next 3 years as well as how the shape of the agency will need to change in the short to mid term.

Senior Business Analyst at Havas Media Group

12 Months

Working for HMG has afforded me the opportunity to work on some very interesting projects for a very large forward thinking and progressive client.

I have been central in modelling the business case, implementing and finally launching a DMP and the subsequent strategy over the next 9 months. Ultimately this caused the client to completely rethink their marketing strategy. They moved away from 'campaigns' to 'always on programs of activity' combined with audience centric, people based, planning and media execution. I was central in defining ways of working and corresponding segmentation and data strategy.

I have also led the introduction and adoption of MCA into the organisation and agency. Through this the client has seen an evolution of how programmatic media is bought and measured in near real-time.

As clients' data needs have evolved so to do their data and measurement strategies. I have developed data strategies which are empowering the latest methods of buying media including applying data, forecasting and modelling from strategy through to evaluation.

I worked with James for 4 years at Cogent Elliott and during that time it became evident that James had a very impressive knowledge and knack for all things search and conversion, PPC and analytics.

James is not afraid to get elbows deep in data and would often be found writing his own SQL queries to drill down into data. He has a keen eye for analytical detail and also a strong technical background which means he is comfortable wearing many different hats, from configuring Google AdWords campaigns to writing JavaScript tracking snippets for Google Analytics and everything in between.

James is also a great guy with a very personable nature, he is always willing to take time out to help others. I'd happily work alongside James any day of the week.
