      Startup Review from Alexa Ginsberg

      What stood out most about working with AppMakers USA was how attentive and helpful the team was throughout the project. They listened to our feedback, kept us updated and were always available when we had questions. Everything was handled professionally and we felt confident that our project was in good hands. Were very pleased with the final outcome!

    • Roei Schneider
      Roei Schneider IT at Ness
      5.0 ★

      Startup Review from Roei Schneider

      I work in IT support, so I was probably more interested in whether this would save us headaches than whether it looked impressive. AppMakers spent time understanding why tickets were getting stuck and found that a lot of our delays were actually caused by people not knowing who was supposed to do the next step. That was a very simple observation, but we had never really stepped back and looked at it that way. The system they planned would make ownership much clearer and let employees see what is happening without constantly asking us for updates. I liked working with them and would do it again.

      eCommerce Development Review from Robb Fahrion

      We were creating a product in the advertising technology environment. It was a product for publishers to improve their revenue by making a dynamic inventory on their side and getting more income out of their advertising. We needed help with the recruitment of an outsourced, part-time frontend developer with broad experience and availability.
