    AppMakers USA Reviews & Testimonials

    • Liana Gudin
      Liana Gudin Operations Manager at Etage
      5.0

      Project-based Review from Liana Gudin

      At one point we realized two teams were both assuming the other one had picked up a pretty important internal request, and it just sat there. That was kind of the moment we knew we needed help. AppMakers came in, asked smart questions, and helped us trace where communication was breaking down. They didnt overcomplicate it. By the end of the R&D, we had a clear picture of the problem and a realistic plan for fixing it. It was genuinely useful.

      Cross-Platform Review from Awital Ifrah

      Masa came in with a pretty loose idea and AppMakers helped turn it into something solid. What I appreciated most is they didn't overcomplicate it or try to make it into some giant monster platform. They listened, asked smart questions, and helped us focus on what would actually matter for alumni and current participants. The end result felt thoughtful and realistic. I'd definitely work with them again.

      5.0

      Startup Review from Moishi Stern

      We create live events. We wanted a site that shows what we do without making people dig. AppMakers listened, trimmed the fluff, and gave us pages that read fast and look good on a phone. The quote form asks the right things and our team can update galleries without calling a developer. They stayed on schedule and answered messages the same day. The whole process was calm and clear. We already see better inquiries. It feels like a real upgrade, even before the full rebuild.
