What Clients Say

"We needed someone to tell us the truth about our web analytics, and Gunnar delivered it with style. His audit confirmed we'd built something solid with Exactag and Google Analytics, and the detail of his analysis made the technical complexity click. His in-depth reports gave us permission to be confident about what our data was telling us."

Thiago Pojda Data Ops Director @ SIXT

"As part of our transition from Universal Analytics to GA4, we worked with Gunnar Griese to run internal workshops and training sessions for both specialists and business users. Gunnar has an impressive depth of knowledge in Google Analytics and combines strong technical skills with the ability to communicate complex topics in a clear and accessible way. His contribution made a real difference to our organisation's understanding and use of GA4. I can wholeheartedly recommend Gunnar to other companies facing similar challenges."

Dennis Vesti Brorsen Data & Intelligence Director @ JFM

"Gunnar is a 'thesis of excellence' in relation to all things Google Analytics, GTM and almost all surrounded tech. I have the utmost trust in his work as well as the structure of the same."

Stefan Bovien Nielsen Digital Commerce Lead @ Comwell Hotels

"Working with Gunnar has been instrumental in levelling up our data capabilities across the board. He led the implementation of our GA4 setup, trained our team to maximize its potential, and then helped us build a Marketing Data Warehouse in BigQuery using Dataform as a solid, scalable foundation for our data. The Looker Studio reporting he set up on top of that has made our data genuinely actionable for the wider team. Beyond the technical delivery, Gunnar has been a trusted sparring partner on how we think about and use data strategically. Highly recommended."

Karri Durchmann Head of Digital @ Beely
