“Stop selling, start helping.”

Welcome to my website!

I help motivated entrepreneurs and marketers grow online in leads, customers and profit. I am the founder of AdFunnel, an agency specialized in paid traffic and online sales funnels.

Because of all the distraction, I notice that companies sometimes forget what really drives their business, namely growth in satisfied customers and profit! It is my passion to realize growth with online customer journeys. Not only growth for now, but also for the long term.

I have been immersing myself in growth marketing since 2011. I started at an online marketing agency, where I learned the first tricks of the trade. After that I worked at large companies such as RTL Nederland, Coolblue and Verizon, but also helped startups, agencies and local businesses.

I have tested endlessly with tools and funnels, both for my customers and for my own company. Believe me, I paid enough learning money for a lifetime! Because of this I now know how you can effectively realize leads and customers with digital strategies. And I enjoy it every day!

Can I help everyone? No. But are you an e-commerce, SaaS or B2B company? Or a solo-entrepreneur? Then there is a good chance that I can find new growth potential.

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