Azumo Reviews & Testimonials
Michael S. Director at Software Development Company
5.0★
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.

AppMakers USA Reviews & Testimonials
Awital Ifrah Program manager at Masa Israel journey
5.0★
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.

Moishi Stern Customer support at Madlan
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.

5.0★
Mobile App Development Review from Laura Waniuk
During my tenure at Beaver Creek Resort Company I was tasked with building and launching a guest-facing app for the hundreds of thousands of visitors to Beaver Creek Mountain. I worked very closely with Quartus Technology and their team to meet the budget, the timeline and all the required features for the project. The app launched early! It's been an incredible success and the app has continued into phase 2 and 3 with added functions. I highly recommend Quartus Technology if you are in search of a quality app, strong development team and transparent pricing.

Chris Caputo, PMP Director of Project Management at CATIC

Mobile App Development Review from Chris Caputo, PMP
After looking at multiple vendors to build an app to provide information on municipalities we selected Quartus. The scope included the development of the app (including designs) and integration to a service that our development team created. Quartus was successful. They delivered in a timely, cost-efficient manner and were easy to work with. When we decided to have a second app created, we did not look elsewhere and stayed with Quartus. This app involved the development of a calculator to calculate and email title insurance premiums. Like our first app, Quartus had to develop the designs (they were able to leverage a portion of the work from our first app) and integrate to a different service that our development team created. Once again, Quartus delivered. These apps were for Android and iOS. They are a good partner.

You can't beat the VLink guys when it comes to designing and developing. From the start, I hired them to build my website and gave them all my specifications and preferences. I was very happy with their work and they advised me on some better alternatives where possible. Their assistance with all stages of designing and developing our website, from the first interaction to the launch, was invaluable. All of the components of the project were delivered on time, with excellent quality, and they provided satisfactory support until the end. I would recommend them without hesitation.

I have found working with VLink to be an exceptional experience despite my initial trepidation regarding establishing a relationship with a company situated so far away.The VLink experts have strived for excellence, no matter how difficult it has proven to be. After receiving a product of the highest quality, my expectations had been exceeded. I was impressed by the professionalism, responsiveness, and patience of the project manager who dealt with my requirements. Even the amount that was quoted to me was in line with my expectations. Now I consider myself to have gotten more for my money than I expected.

We experienced a breath of fresh air when we switched to VLink's Managed Solution. They carefully analyzed our entire ecosystem and offered multiple recommendations for improving our system (not just one). They also implemented various cost-saving measures. We incrementally upgraded our equipment and software solution as needed. You can choose from a variety of options, and they will work according to your timeline, your needs, your budget, and your staff's ability to change. I have not detected a lapse-in fact as far as knowledge is concerned, and I have learned much from them! Which is of particular importance since we work around the clock.
