We have done business with Stem Design for a project of great importance for the company. Their mandate was to build a new transactional website including several countries, several languages, several currencies, several products and all this in an ultra-tight deadline.

Stephano and his team took up the challenge and gave us an amazing tool. They were very responsive and helpful throughout the entire process, from day 1. This new transactional platform has become the turning point in our marketing strategy. We can now execute our strategy and maximize our platform with the help of Stefano and his team. During this project, we did not only create a new platform, we also found a great, highly qualified and valuable partner to push our ideas and future projects, which is priceless !

We have had a great experience with Stem Design, they helped me on every level two produce two shoppable websites in 2 short months they were able to deliver a flawless product. They started with the design process and walked me through every step of the way to the banking and check out process as well as updates on my end.

Stem Design has been nothing short of amazing in helping us launch our first clothing line. They provided us with options and solutions to all of our initial questions and delivered in a timely and professional manner. We felt at ease working with them to get our store exactly in line with our original vision.


I worked with Stefano at Stem Design. We had some issues with the spacing of content in our theme (Header needing more content, titles taking up too much space and pushing content down, margins not wide enough, footer taking up too much space).

Stefano responded to my request immediately and, despite having a lot of work that week already, made all the necessary corrections in his extra time and finished the project within a week. He was also very open to follow up requests which allowed us to really dial in the look that we wanted. Great experience and will be going back to Stem Design for any future website needs.
