Allow me to introduce myself: Erik Hooijer

Hi, I’m the founder of FitMarketing and your strategic partner in making HubSpot and RevOps actually work for your business.

With a background in online marketing, web development, and CRM systems, I’ve spent the last decade helping businesses stop the chaos, fix the cracks in their funnels, and build scalable growth systems using tools like HubSpot, AI agents, and automation frameworks.

I'm based in Rhenen, Utrecht but work with clients across Europe and beyond. What drives me is making complex systems easy and actionable for growing teams.

We help companies like:

CRM Migration & System Architecture

We handle complex migrations from tools like Salesforce, Zoho, or spreadsheets—mapping your data into a clean, scalable CRM structure in HubSpot.

FitMarketing is great partner to set up and maintain a robust and scalable HubSpot infrastructure

I've had the pleasure of collaborating with Erik from FitMarketing in my role as VP of Marketing at two different high-growth B2B technology companies. At both companies, we adopted a data-driven sales strategy, requiring a CRM capable of robust data processing and maintaining clean data. I have been very satisfied with Erik's work and have sought his expertise on multiple occasions. There are many HubSpot consultants capable of performing basic CRM tasks; however, Erik distinguishes himself through his profound expertise from over 10 years working as HubSpot expert. He possesses the ability to develop systems that not only scale effectively but also ensure the cleanliness of data and reports for the company, while simultaneously minimizing administrative tasks for the sales team.
