An everyday partner

We work on a daily basis with MI4's teams as part of the roll-out of our Group CRM, on both the sales and marketing sides: scoping, parameterization, training, support... This project represents a real transformation challenge for our organization, and we can count on a committed, professional and attentive team. Despite the complexity of our structure and our IS ecosystem, MI4 has positioned itself as a real day-to-day partner. Their detailed understanding of our challenges, their ability to propose relevant solutions and their responsiveness in implementing them are particularly appreciated. Their support gives us real confidence, both technically and methodologically. A big thank you to the whole team for their availability and involvement - with a special mention to Manon and Loïc, whose commitment and expertise were decisive in the success of our project. A fluid, efficient and valuable collaboration. We recommend them without hesitation.

HubSpot training

I was lucky enough to be trained by Irina on HubSpot and I can't recommend her highly enough! Her explanations were clear, precise and well adapted to our respective levels (and according to the work we had done beforehand). Thanks to her pedagogy and kindness, I was able to gain autonomy and confidence in using HubSpot. More than just the training, she was also on hand to answer all our questions between sessions. A truly enriching training experience! Many thanks to her,

Thanks to their expertise, we now have a CRM perfectly adapted to our internal processes, which saves us considerable time and improves the quality of our data. A smooth and efficient collaboration that we recommend without reservation.

Excellent collaboration with MI4 for HubSpot implementation

We called on MI4 to implement HubSpot as our CRM solution, and we're very satisfied with this collaboration. Sarah, our consultant, demonstrated a remarkable understanding of our complex issues. She was able to analyze our specific needs and structure our CRM optimally, creating customized automations perfectly adapted to our processes. Her approach was remarkable: very attentive, patient and attentive to our constraints. I highly recommend MI4 for their technical professionalism and human qualities. A team that knows how to combine expertise and interpersonal skills, which makes all the difference in this type of project.
