Customer reviews

Trusted when builds get real

When we created a product from scratch for the first time, we needed guidance and Mezz Solutions delivered. Their communication helped us understand each step of the development process, and their creative expertise turned our concept into an award-winning design. Mert was a dedicated and trustworthy partner, making the collaboration seamless and enjoyable. Thanks to Mezz Solutions, our product creation journey was a success.

Jon Semira CEO, Wavee Group Inc.

Our project was not easy and Mert and his team made a very quick impressive demo. We were convinced that Mezz Solutions could deliver what is needed for our product and they did. I am very happy with Mert's very responsible approach for the whole project from the beginning to last minute we made the production. Thanks to Mezz Solutions that we had a very stable, reliable product with amazing functions.

Alan Cook Founder & CEO, Brilliant Pet 2 LLC

Before knowing Mert, I was having problems with my supplier in China for not being able to deliver a result after total 2 years! Once Mert and his team involved and they helped us negotiate with and change the supplier, and transferred the mold. The process was not simple but they made it. Once all moved, they delivered my products with an exceptional quality in a very short time. Very efficient! Looking forward to our future cooperation. We have more project ideas for next year and Mezz Solutions will be definitely my partner.

Tim O'Connell Founder, Canopi Plants

We were introduced to Mezz through trusted advisors who had worked with them extensively. They were responsive, communicated clearly in English, quickly understood our needs, and kept us informed throughout the process. Samples were provided for verification, and the final products perform very well. We would highly recommend them
