Joris Sjamaar

Creating a conversion funnel? That’s no longer a challenge. Google Ads campaigns are no longer new either. But building an online customer journey that is seamlessly aligned and that is largely automated at the back, remains a major challenge for companies. Let alone measuring this customer journey in the right way.

Welcome to my website. My name is Joris Sjamaar and I have 10+ years of experience in e-commerce and B2B customer journeys. I grew up in Brabant and studied marketing at Tilburg University. After that I moved to Amsterdam for love and the best jobs. In addition to my interim jobs at corporates and scale-ups, I own a sports platform called CrossAthletes and I build premium WordPress websites.

I don’t believe in channel thinking, I believe in customer journeys. Customers don’t think in terms of channels, but assess the total experience with your company and this is always a combination of touchpoints. By genuinely helping (potential) customers and offering a unique experience in every phase, you do the very best marketing. This will give you a competitive advantage and ensure that people will talk about you on birthdays.

The digital revolution has changed marketing. Technology enables us to connect more effectively with (potential) customers on a large scale. Marketing is also becoming increasingly data-driven. Gaining insight into what drives your customers will make the difference in every touchpoint. With a strong background in online marketing, product management and CX, I help companies grow in more satisfied customers and profit.

It’s impressive how Joris is able to breakdown complex customer journeys and makes them easy to understand for the rest of the team.
