Marketing Guys/ Janssen & Janssen

I recently attended a training session at Marketing Guys, led by Jeroen. He explains everything incredibly clearly and accessibly. What I particularly appreciate is that there is always room to brainstorm further whenever you need to. This ensures you remain well-supported while improving your hodgepodge.

Practical guidance and clear support

We had a very positive experience with Marketing Guys. They were quick to respond to our questions beforehand, and during the training they showed a great willingness to think along with us and provide clear support. They also took the time to address specific cases and offered helpful suggestions on how we could improve certain areas. Thank you Wouter, Thomas and Caroline for the great service.

Very capable and know what they're doing

Marketing Guys is really great at tying all ends together, aligning our marketing efforts and targets with the sales team's targets. They manage to keep an overview of all the things that we do and either provide assistance or take on entire projects all together. They have an in depth knowledge about HubSpot and all other marketing tools and are a pleasure to work with.

A great partner for the long term

We have been a customer of Marketing Guys for years. They initially helped us with the implementation of Act-On and recently with the transition to HubSpot. In addition, we brainstorm every month about our content marketing strategy, and they keep me updated on the latest market developments. My experience is that they continuously think in solutions, research everything you ask them, and go the extra mile. A great partner for the long term!

Proactieve samenwerking om impact te vergroten

Werken met merketing guys zorgde ervoor dat we HubSpot zijn gaan gebruiken waar het echt voor bedoeld is. een prachtig system waar veel mee kan maar wij maakte er niet optimaal geb ruik van. In een aantal sessies wist marketing guys de essentie uit ons vraagstuk te halen en het team te helpen met implementeren. Als er vragen waren wordt er altijd snel geschakeld. En als zij eerder iets zien worden we er proactief op gewezen. een aanrader

Following up and supporting you all the way

Overall we had a great experience with Marketing Guys as an external agency. They were flexible, came to our offices multiple time to help us with training and onboarding and are still keeping an eye on the integration today to make sure that we're following up on areas where we need to be careful. They were super accessible and are always eager to help and brainstorm ideas - 10/10 would recommend.

Implementatie van HubSpot

“MarketingGuys heeft ons geholpen bij de implementatie van de HubSpot Marketing- én SalesHub. Inmiddels hebben we ook de ServiceHub geïmplementeerd waardoor processen naadloos op elkaar zijn aangesloten. Het advies, de implementatie en de begeleiding maakt dat ik MarketingGuys van harte aanbeveel.”

Flexibele & pragmatische aanpak

Patrick, Marten & Jeroen hebben ons geholpen met de technische onboarding van HubSpot & de integratie met Salesforce. Met een pragmatische aanpak vanaf Marketing Guys hebben we in een korte periode veel voor elkaar gekregen. Binnen 2 maanden wouden we graag migreren van SF Pardot naar HubSpot inclusief werkende integratie. Marketing Guys is flexibel maar ook duidelijk in het scheppen van verwachtingen. Uiteindelijk zijn we heel blij om zonder issues & binnen de deadline live te gaan met HubSpot. Thanks heren!
