      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.

      Amasta Media exceeded all my expectations in creating the website for my psychiatric private practice. They are a high end firm, with sophisticated designs, as well as, deep technical knowledge. Their guidance about the best places to go for hosting, business email and analytics were invaluable. They are responsive, meticulous and relentlessly driven to deliver. It was such a pleasure to work with them.

      Igymdaily's Review Sourced from Google

      Highly Recommend – Outstanding Web Development Service! I recently hired sansarahub to help build and optimize my supplement affiliate website, and I couldn’t be happier with the results. From the very beginning, their level of professionalism stood out. They took the time to fully understand my brief, asked the right questions, and quickly grasped the goals I had in mind for the project. What impressed me most was how they delivered well beyond my expectations — not only in terms of functionality and design, but also with attention to detail. Communication was smooth throughout the entire process, and they were always responsive, transparent, and open to feedback. The end result is a clean website that flows beautifully and presents my brand how I envisioned it. If you’re looking for a reliable, skilled, and easy-to-work-with developer, I highly recommend sansarahub. I’ll definitely be working with them again for future projects. Thanks again for the great work!

      David Dorough's Review Sourced from Google

      I read reviews of almost 100 companies and spoke with reps from 5 before finally going with Appingine for my first app. I'm sure you can pay more for less quality from a different company but why would you? They were easy to work with and quick to respond to questions. They split the charges by stage of development like every professional company should. I needed to make several changes during development and the cost was reasonable. Anthony was awesome and helped me along every step of the way. Apple has more stringent requirements than Google and Appingine was able to get the app published on both stores. Looking forward to more projects with them. Once again, don't pay more for less, go with Appingine!
