ABOUT
Corné van
Willigen.
I build businesses, products,
and practical ideas.
ROIhacking brings together my projects and the teams I work with, from ecommerce and email to technology and practical business ideas.
THE WORK
Different projects.
A shared curiosity.
Some projects are established businesses. Others are taking shape. Each has its own page, with a clear introduction and current availability.
