Hi, I'm Guido!

I'm an accomplished cognitive psychologist and customer experience optimization specialist. With a track record in e-commerce since 2008, I'm currently the Global Business & Technology Evangelist at Spryker. Notable achievements include building optimization teams, directing global communities, and hosting an award-winning podcast, CRO.CAFE. I have a knack for transforming user data into customer success and business growth. A well-known figure on the international stage, and I love to regularly share my expertise at global events.

To answer a common question right out of the gate: Yes, the X in my name is not just there for decorative reasons: my second name is Xavier!


I was born in 1982 in Zwolle, in the Netherlands. I lived in Hattem, Tiel, Amersfoort, Utrecht, Breukelen (yes, Brooklyn), Hoofddorp, Amsterdam and I now live in Ouderkerk aan de Amstel (a suburb of Amsterdam).

Until 2004 I spent most of my time swimming, won several Dutch championships and participated in European championship tournaments.

I studied Applied Cognitive Psychology at the University of Utrecht. I was board member of the Student Group of Social Sciences (SGS) in 2006/2007. For more info about my study/CV you can take a look at my LinkedIn Profile.

Professional Experience

  • I have spent the past decade working on improving digital customer experiences;
  • Working with mixed teams of stakeholders, analysts, researchers, ux/ui designers and developers, both locally and internationally;
  • Setting up and leading user experience and conversion optimisation teams;
  • Setting up usability and A/B testing procedures;
  • Advance and empower team members through open collaboration, education and thought leadership;
  • Sharing knowledge: blogging and speaking about E-commerce, (Online) Psychology, digital user experience and community building at conferences around the world.

Online Communities and Events

My main involvement lies with web-based software applications and the communities involved with it. I founded one of the largest local Joomla! communities worldwide and I was a Dutch translation coordinator for the platform for quite some time. I also organized the two-day event Joomladays in 2009.

I switched focus to e-commerce and between 2008 and 2021 focussed on one system in particular: Magento.  I organized the first worldwide Meet Magento event in 2009, organized 11 events in total and expanded the conference to over 550 yearly participants. This makes it one of the biggest Magento events worldwide and the start of a global movement of over 60 events.

In 2021 it was time to focus on something new and I became the Global Business & Technology Evangelist at the digital commerce visionairy Spryker.
