Collatz - Web & Marketing Consulting

After shuffling around on Fiverr and looking for other cheap solutions, I ended up at home in my own duck pond with Collatz. Jacob is exactly the knowledge and quality control you need as a business developer who does not have webshop focus or competence himself. Holistic, precise, qualified. We have landed with the consultant we belong to.

We entered into a collaboration with Collatz – Web & Marketing Consulting to develop our webshop, and the project was carried out both efficiently and professionally. Jacob has been very accessible throughout the process and has ensured clear communication and quick follow-up on all inquiries. The delivery fully meets our expectations, and we experience Collatz – Web & Marketing Consulting as a competent and solution-oriented partner. We can highly recommend them to other companies looking for a reliable supplier of web development. C-STAAL ApS - Carsten

Collatz Web & Marketing Consulting stepped in with 1 hour's notice when we unexpectedly needed to build a brand new Wordpress website for a customer in mid-December 2025. Jacob helped with everything technical, such as setup, installation, identification of relevant templates/themes and subsequent adaptation to the design line. The time factor played an extremely important role for us, but Jacob was very quick to understand our problem and made himself available - even after work - with adaptation, troubleshooting and picking up, so that we got to the finish line on time.
