And more awesomeness


I’ve always had a thing for people. During high school I found it fascinating how different people responded to different situations, whether it be a relationship breakup or buying their lunch in the supermarket. These quite often irrational decisions sparked my interest in psychology. Because I was good at talking to people and my caring nature, I thought I wanted to become a psychologist.

Then came the internet. I loved everything about it. The games, the websites, the speed of improvement. I was instantly hooked and started to explore everything. making websites, the dark web, bitcoins, torrents, you name it. So, I had two big interests: the human and the internet.

Internet meant data. Data meant psychological insights. But the real question is: what do you do with all those data and insights? You try to validate these new assumptions with more data. All I’m doing is diving into the mind of the customer to you get ahead of your competitors. And the best part is:

I teach you how to do it yourself, so you can actually do it yourself.
