    • Yaakov Babani
      Yaakov Babani Manager at Growth Co.
      5.0

      Small Business Review from Yaakov Babani

      I work in client partnerships and one of the hardest things is remembering the context behind every relationship when you have a lot of them going at once. AppMakers NY created a better way to do that. At one point there was a client that had mentioned the same frustration three times and because the notes were scattered around, that pattern was completely missed. That alone made the project worth it. The team helped develop something that would actually be useful during a busy week, not another system people forget to update. I liked working with them and would absolutely use them for future projects.

      Our goal was to build a scalable, robust solution based on cloud computing. The software should be able to offer multiple complex services online, including e-commerce and high-performance computing. So we chose Light IT to do the job. 3 words to describe the cooperation process would be flexibility, quality, and responsiveness. We always felt that the project team was working on our behalf, and our tight collaboration produced excellent results.
