      eCommerce Development Review from Drew Hayner

      The ShirtSmart website had to be moved from an outdated hosting platform and integrated into the Big Commerce platform. There were hundreds of apparel products all with multiple colors/sizes, sizing charts, etc. Very pleased with the whole project. I turned everything over to Duck Soup and had no problems!

      BigCommerce Review from Anne Altor

      Danielle helped us migrate our website from Wordpress to BigCommerce. With her support, the process was smooth, quick and cost-effective. We subscribe to a basic Duck Soup support plan and we appreciate how quickly Danielle responds to our questions and helps us find solutions. Her technical skills are excellent too - she continues to help us implement updates to our website. Highly recommended!

      Duck Soup and Danielle has helped us tremendously with the management, fixing and upgrade of our Big Commence environment. I do not think that we would have been able to manage the environment for the last 5 + years as well without Danielle's help! she is AMAZINGGary Acephoto.net

      Mobile App Development Review from Domenic Fraboni

      We couldn't be more pleased with our experience with TouchZen. They took over a bad situation left behind by our previous development team and have been able to continue to build new features while cleaning up the old project. We have been very pleased with their developers responsiveness as well as the project management. I would highly recommend working with them for any of your web or mobile app development needs.

      B2C Apps Review from Brett Lassig

      We have been extremely impressed with TouchZen's development team behind the Get Cover Mobile App. Their approach has been collaborative, and responsive to the needs of our warranty and claims environment.The app is intuitive for end users while still delivering the robust functionality needed on the backend, especially around claims processing, and real-time updates.Their diligence has made a significant impact. Features like streamlined claim submission, status tracking, have enhanced both customer satisfaction and operational efficiency.Overall, this highly capable and professional development team has delivered quality work and stands behind it. We look forward to continuing to build and scale with them.

      Mobile App Development Review from Dr Asa Frey

      They worked on our app and continue to work on it to this day. We originally had a bad experience with various developers and ended up with a bunch of code and no functioning app - touchzen took the code and audited it and made it work and it work great now. Can't complain - still going to work with them and I would recommend to anyone who wants it done right.

      Brand Design Review from Benjamin Finkhousen

      Gyst is so wonderful to work with. They are very professional and really put an effort into what they do. They delivered a service that was invaluable to our company.We had them rebrand our company and design an all new website based on that branding. The work they did was impressive. They did a complete dive into our field of expertise, including researching our competitors to help get us ahead. We received a full brand guide that identified weaknesses and strengths, to see how we could gain an edge in the market. They then applied these lessons to create our new look. The end result was a beautiful logo and website that really picked up our brand. They designed it ground up with our industry and company in mind, and that’s why it really expresses who we are and what we are about.A huge shoutout to Sarah and her team!
