Jakub has been practicing and writing about UI design for over a decade with the most visible work being published at GoodUI.org. The central idea behind the GoodUI project is to identify effective UI patterns. In the long run, Jakub’s goal is to build out a solid repository of evidence showing clearly which ideas work better and which ones less so. This evidence based approach to design is being pursued to make life easier for designers, marketers and optimization experts with A/B tests of the highest quality.

Aside of writing about UI and conversion optimization, Jakub Linowski also runs a consulting company , serving a variety of online businesses. The company has been increasing conversions such as revenue, sales and leads for clients since 2013. Linowski designs and runs A/B tests while applying various optimization strategies with a median improvement track record of +23% across past projects.
