Profile bio

About Marijn Buizer

I am passionate about how data can help companies develop growth and become more efficient. Whether data is used to design new products, get a competitive edge, increase sales, revenue and profits, or increase customer satisfaction, in my experience there is data within companies and everywhere on the web to unlock the hidden potential.At the companies I worked for, I found that using internal and external data was always an extensive process, expensive and felt like a black box. I wanted to change that by creating a unique company with resources in Europe and Asia to make affordable data solutions to grow a company based on internal and external data.We build data driven solutions and implement the necessary tooling to unlock this potential. And specifically we build data warehouses, Dashboarding, Predictive modelling and competitive scraping solutions. If you are interested in these topics please follow or connect.

Listed skills include Analysis, Advertising, Wholesale, Retail, and 13 others.
