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.

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.

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.

Small Business Review from Jubilee Haddasah Munozvilla

Software Development Review from Jeremy Ott
This team was extremely responsive from the start. They pulled together a comprehensive quote for my MVP and have delivered on all of the requirements. The daily updates from the product/project manager are extremely helpful and it’s clear that the team cares about the quality of work they deliver. The engineers working on the product are always willing to make recommendations and go above and beyond to make the experience and underlying infrastructure that much better.

eCommerce Development Review from Luc Vlekken
We've had the pleasure of working closely with this development team on several projects, and the experience has been consistently excellent. Not only are they highly skilled developers, but they also think along with us both from a technical and a product/customer perspective. Their proactive attitude, reliability, and ability to translate complex requirements into elegant solutions make them a true partner rather than just a supplier. Highly recommended.

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.

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.
