Full recommendation for the Growth Ninjas

Growth Ninjas provided us with excellent support during the CRM implementation. The collaboration was professional, structured and very solution-oriented right from the start. What was particularly positive was how quickly the team got to grips with our requirements and turned them into a practicable solution. In addition, there was a high level of reliability, fast response times and a really pleasant working relationship. A clear recommendation for anyone looking for a strong partner in the field of CRM and process optimization.

Very satisfied and to be recommended

From the very beginning, the collaboration was very pleasant with the necessary drive and professionalism. We focused our collaboration on custom APIs and reporting. Viktor deserves a special mention from the team, who provided us with reliable support and results on a weekly basis.

Grandiose

We have had HubSpot for 5 years now and have only ever used about 30% of it. After I asked HubSpot for help, I came across Growthninjas, since then I think we have been exploiting the full potential for us. Many thanks for the great help and good cooperation!

Efficient and professional HubSpot landing page design

The collaboration with Stefan and the Growth Ninjas was efficient and professional. They really went the extra mile, especially when creating our landing pages in HubSpot. They immediately understood our wishes/requirements and implemented the pages at lightning speed and in great quality. It was immediately apparent that they knew their way around HubSpot and were also familiar with the financial sector. As a result, communication and implementation ran smoothly and we are very satisfied with the new, optimized landing pages. We can therefore recommend the Growth Ninjas unconditionally for all HubSpot topics.

Top support: fast, uncomplicated, efficient and lots of knowledge

Our expectations were more than exceeded. Growth Ninjas not only helped us with the migration and implementation, but also took over the on-boarding with our sales and set up and trained us on important functions such as sequences, mailings, templates, etc.. I would recommend them 100% and work with them again and again. Thank you. RP

We worked with Growth Ninjas to adapt HubSpot to our internal structures—and we’re very pleased with the results. The team supported us with a strategic and well-thought-out approach that helped us make the most of HubSpot’s capabilities. Throughout the project, they were professional, responsive, flexible, and always helpful. Their expertise made a real difference, and we felt well supported at every step.
