      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

      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.

      AI Automation Review from Alessia Anticoli

      We partnered with AppMakers to explore an AI-powered solution that could simplify the way our marketing team manages content across multiple hospitality properties. From the beginning, their team focused on understanding our actual workflow rather than proposing a generic solution. They carefully analyzed how we organize photos, approve captions, coordinate promotions, and manage content between different properties. Through the research phase, they identified several inefficiencies we hadn't fully recognized, including duplicated work and unclear approval processes. They then presented a well-structured concept for a shared platform with dedicated content libraries, approval workflows, and AI-powered writing assistance tailored to the unique voice of each property. Communication was always smooth, timelines were respected, and the entire process felt collaborative and well organized. What impressed us most was their understanding that every hospitality brand needs its own identity, and that technology should support that rather than standardize it. The project gave us a much clearer roadmap for improving our internal marketing operations, and we would gladly recommend AppMakers to any company looking to combine AI with practical, business-focused solutions.

      We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

      UI/UX Design Review from Wladimir Wolinski

      Communication was smooth either through our teams communication channel or with the project manager via email. We were in daily contact with the UX/UI designer in form of dailies or when we had to clarify some questions. With the project manager, we had a short conversation every 2 weeks to clarify all possible questions.We personally love to work in a very process-oriented way. Because when we understand how to do something, we usually know how the end result can look like. With Digis, we also had the feeling that they knew what they were doing and how to do it. Every next step was planned from the beginning. If something didn't work in line with our processes, we could readjust it.We were basically satisfied with everything.

      Both the developer and tester have exceeded expectations. Their performance is excellent. Together they eliminated bugs, introduced new features, and ensured that the app is working without problems. Previously, we had many complaints in the app store. Since working with this developer and tester, these complaints about the app functioning and bugs have disappeared.The time zone different is sometimes challenging, since we are in California and they are in Europe.

      UI/UX Design Review from Jamie Flett

      Chimpare Design Lab helped us with a UI/UX research process, which included in-person interviews where they walked users through unboxing, connecting, and using the features of our smart air conditioner. From there, the team took the findings and produced a report for us to make improvements to our app and increase our activation rates. In addition to the report, Momentum Design Lab also redesigned some parts of our app using Figma.The project required a very iterative process, so we required more than one discovery call to get started. In fact, they didn't just work with me; we also integrated our consumer marketing insights team to identify participants. We also collaborated with them to figure out how to recruit the right users based on our target customer profiles.

Then every week, we had an update call with a couple of new developers that were recommended our way. They did an outstanding job. I signed 2 developers. Everything went smoothly as I had hoped.
