About data science

Our Data Science department at GWI is committed to maintaining the highest quality in our survey data and to helping our customers arrive at the insights they need to understand their audiences. From automated testing and intelligent product features to custom analytical solutions and data observability, we are supporting the business at every level as data is at the very core of what we do. We are actively engaged throughout the entire data life cycle including data cleaning, data processing, data validation, designing and automating data workflows as well as automatically identifying and recommending insights and unexpected findings to our users.


Our team values learning and keeping abreast of the latest research very highly and as a result we’re applying a wide range of techniques across machine learning, statistical analysis and natural language processing to the services and features we build. We are a diverse team with different backgrounds spread across two locations, Athens and London, and growing rapidly. We are at a very exciting junction where we are experimenting with cloud computing technologies as we want to shift towards full ownership of our own Data Platform.
