Building lasting optimizations

As an entrepreneur, you’re in the game to win. And to win the game, you need to convert visitors to take action or make a purchase.

That proven framework is built on data, numbers, metrics and analyses. We act fast and quickly and generate as many viable tests as we can in order to drive results.

About me

I'm Bas.

During my employment at an agency, I worked on digital strategy, customer profiling, marketing automation, digital campaigns and gave trainings to clients in sports and publishing. 

My job is to find the alternative angle, put it into practice, and improve bottom line results. Because I’m in the business of driving profits, not clicks.

I also joined Tekkieworden as growth marketing expert, an initiative by, Rabobank and the Municipality of Amsterdam to get more people into tech jobs.

You’re reading this. Therefore, it is very likely that you have started exploring your options in finding a(nother) digital marketing specialist. Perhaps your team reached a plateau. Or your current agency is slow, bulky, and spends lump sums of your ad budget without returning actual results or learnings.

While I cannot guarantee overnight success, I can assure you that my methodology is both easy to follow and has proven to drives results over time.
