Welcome to X+Y!

We are a freelance and research agency that empowers data scientists to make impact for their industry and for the society with the newest academic insights. 





What we do

There is a high demand for data scientists and the trend is here to stay. Data scientists have different backgrounds including: econometrics, artificial intelligence, mathematics, computer science, physics, and many more.
These data scientists are smart and ambitious people that would like to continue learning and make an impact for society. However, current vacancies usually don’t perfectly match the unique expertise of the data scientist. And maybe the learning goals will change over time. With this situation in mind, we are dedicated to help these data scientists.

How are we going to do that?

X+Y is a freelance agency for data scientists by data scientists focussed on your goals. Being free and independent, without being alone. In order to stay intellectually challenged, we use the profit of the corporate projects to fund research projects that we and our freelancers are interested in. We believe that you don’t need a university to be a researcher.
