Great Service

I had the pleasure of working with Diego who made what could have been a complex and overwhelming system feel intuitive and manageable. His ability to break down technical concepts into clear, practical steps really stood out, and he ensured everyone felt confident using the platform by the end of the training. What impressed me most was his patience and adaptability to how our business structure operates. He took the time to answer every question thoroughly and tailored examples to real-world scenarios relevant to our work, which made the sessions highly engaging and useful. Their enthusiasm and deep knowledge of CRM systems were evident throughout. Thanks to his guidance, our team has not only improved efficiency but also gained a much better understanding of how to use CRM tools strategically. I would highly recommend Diego and Leadstreet to anyone looking for a knowledgeable, approachable, and effective trainer.

If you're new to HubSpot, then Diego is your man

We were new to HubSpot. We heard about it from other people in our line of business and so decided to sign up. We were daunted at first by what seemed like a complicated platform but we needn't have worried. Our onboarding guide Diego was great. Like an online Crocodile Dundee he was our guide to the wild's of HubSpot and showed us how to use it. He was clear and concise in his communication and was patient with our progress. A quality that he shares with great teachers. If you're new to HubSpot then Diego in the man to show you around.

From analysis to delivery: Leadstreet makes the difference

We are extremely satisfied with our cooperation with Leadstreet. From the start of the project, their structured approach and professional execution immediately stood out. Everything went smoothly and the communication was really flawless. Within a short period of time they managed to deliver a complex project quickly and efficiently. What positively surprised us was that they asked the right critical questions and actively thought along about automations we had not yet thought of. In short: a real winner to work with if you use HubSpot as a tool. Leadstreet combines speed, quality and insight in a way that inspires confidence and delivers results.

Seamless collaboration and great support

Working with leadstreet on BerryAlloc’s MyFloorStyle project has been an absolute pleasure. They helped us set up email automation for our newsletters and built a complete, multilingual content platform from scratch. What truly stood out was their incredibly friendly and fast communication—no question was ever too much, and they always reacted quickly to resolve any issues. Thanks to their expertise, we saved significant time setting up templates for various languages, making ongoing maintenance much more efficient. I especially value their openness, reliability, and consistently high-quality work. Leadstreet’s deep knowledge of HubSpot makes them a trusted partner I highly recommend!

Easily accessible, fast response time, and gets the job done

We worked with Leadstreet for our HubSpot onboarding. The experience with them was very good. They are knowledgable about the platform and provided us with good answers even to very specific questions. Also, they are very responsive to our needs and helped us develop a simple but effective lead scoring model in the CRM that we can easily modify ourselves over time. Job well done!

The complete HubSpot partner

Leadstreet thinks along with your business. As advisor, they have a very deep knowledge of HubSpot. Also a total partner for integrations with external software. Leadstreet not only has the knowledge, but also shares it with their customers. As a result, we built up a highly automated flow with them in a short time. From lead generation (marketing) to file realisation. Fast follow-up and hands-on mentality. Great partner!
