Successful implementation thanks to Pierre's attentiveness and responsiveness

We had the pleasure of working with Pierre for the implementation of our HubSpot and the result is impeccable. In addition to his technical expertise, Pierre was very attentive to our specific needs and extremely available throughout the project. His professionalism and pedagogy made the transition smooth for the whole team. I recommend him with my eyes closed!

5 stars for Jules!

Jules helped us optimize HubSpot (Sales & CSM) and did a great job: clean contact and company files, clear and well-structured sales and CSM pipelines. Very professional, efficient and attentive. Excellent collaboration. There will be more steps in 2026 for sure.

Pipedrive/Monday migration to HubSpot

Jules helped us migrate Pipedrive (CRM), Monday (CSM) and our marketing tools to HubSpot for around thirty users. The scope covered migration from Pipedrive, data organization and cleansing, pipeline and sales process structuring, activity mapping, workflow implementation, as well as the construction of views and dashboards that were genuinely useful on a daily basis for the sales, CSM and board teams. Onboarding and collaborative follow-up enabled us to brainstorm effectively, and Jules played a real sparring partner role in challenging and improving our sales processes.

Pierre did a great job, it went really well thanks to his very professional, tailor-made support!

Klakss went above and beyond

Klakss was an exceptional partner from kickoff to go-live. They handled our CRM migration with meticulous field mapping, sensible deduping, and clear documentation so nothing was lost and adoption was smooth. On HubSpot, they built the right foundations fast: pipelines, lifecycle stages, lead scoring, clean attribution, and automation that actually reflects our sales reality. Their conversational marketing work paid off immediately. Chatflows, forms, and sequences were designed around our buyer journey, not generic templates, which lifted speed-to-lead and gave our team the context to respond intelligently. The team was proactive, transparent on trade-offs, and disciplined in weekly sprints. Risks were flagged early with options, timelines were met, and they stayed on budget. Training was concise and practical, with playbooks our team still uses. Post-launch, reporting finally matches how we run the business, and our data hygiene is night-and-day better. If you need a partner who blends strong technical execution with business sense, Jules from Klakss is the right call.

Top-notch support!

Well done to Pierre from Klakss, who goes out of his way to help us use HubSpot. His kindness and dedication deserve 6 stars!

Very satisfied with our collaboration with Klakss for our project

I'm very satisfied with our collaboration with Pierre on our new Conte de Faits project. He really took the time to understand our issues, from lead management, marketing and automation to coordinating with my partner to divide up the tasks. We now know exactly where we want to go with this project, and we're already starting to get positive feedback from our customers. Everything is much simpler for us on a day-to-day basis, and they clearly feel it in their experience. Pierre is responsive and really involved. Whenever we had a question, even outside our call slots, he went out of his way to be available and get the project moving. He also trained us to make good use of everything he built. The system is clean, clear and easy to learn, with scenarios adapted to each of our scenarios. It was my first time using HubSpot and I was very apprehensive at first, especially when it came to taking out the subscription and building everything. Today, I'm really happy with the final result. We'll be using Klakss again for future updates to our project, and I'll recommend Pierre without hesitation to my business contacts for the implementation of their future CRM.
