AppMakers USA Reviews & Testimonials

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.

Mobile App Development Review from Eliana Lubofsky
AppMakers USA was a great experience! The team was professional, responsive, and easy to work with. They understood my ideas and helped turn them into a quality app. I'd definitely recommend AppMakers USA to anyone looking for reliable app development services.

Startup Review from Alexa Ginsberg
What stood out most about working with AppMakers USA was how attentive and helpful the team was throughout the project. They listened to our feedback, kept us updated and were always available when we had questions. Everything was handled professionally and we felt confident that our project was in good hands. Were very pleased with the final outcome!

SEVEN Reviews & Testimonials

Web Development Review from Antony Matsepa
We engaged SEVEN to help launch a new product with a tight budget and timeline. The agency met our high expectations by delivering on time, within budget, and without bugs. SEVEN built a strong foundation by following our roadmap, managing tasks efficiently, and providing detailed progress reports. I was impressed with the agency's proactive problem-solving, adherence to deadlines, and flexibility. SEVEN became an integral part of our team, offering valuable insights and exceptional project management. SEVEN's client-focused approach and clear communication set it apart from other providers as a reliable technology partner.

Web Development Review from Anthony Clark
SEVEN developed a mobile web-based app for our company, which served as a dashboard for departmental communication. After delivering the custom platform, the agency supported its maintenance to ensure efficiency. SEVEN demonstrated impressive capabilities, and its team members were professional and well-organized. I felt the project progressed slower than expected, partly because our team was slow in providing SEVEN with the necessary resources. Nonetheless, SEVEN's performance and pricing made it a valuable partner.

Mobile App Development Review from Zlatko Medibach
We collaborated with SEVEN to develop a custom Softphone solution with advanced features, and the agency delivered high-quality software on time. Its communication and project management, using tools like Redmine, Skype, and Teams, were exceptional. SEVEN was always available for meetings throughout the collaboration. We were satisfied with the agency's services and support.

I contacted American Logo Developers and requested a Logo Design for my company. Joseph Paul and his team reached out to me and gave me the initial consultation regarding the type of logo I was looking to have created. Joseph and his team were open to all my ideas and made suggestions and feedback to improve my logo design. After completing the logo design Joseph provided great insight on how to move my computer forward long term. Joseph and his team have been true professionals with helping me take my vision and turning it into reality. He is open to feedback and does not stop short of providing excellent customer service and support.

Highly recommended!

Cloudester developed our website from scratch along with our online order management system and kitchen order system.

The system has been working well for years now and we have been able to add various modules as per our business needs. We are able to discuss and communicate with their entire team on Slack and will be continuing working with them for the foreseeable future.

Rosanna Berardi's Review Sourced from Google
My law firm was in need of a new website with a more modern look and feel. After meeting with several web designers in the Buffalo area, Newbird certainly left a lasting impression and was the perfect fit for what we were looking for. We couldn’t be happier with the look and feel of the website and our SEO and conversions have significantly improved because of it. We also use Newbird for our ongoing marketing needs and Lindsay has always been very insightful. I would highly recommend Newbird to anyone looking for web design and digital marketing services.

Elena Sporrer's Review Sourced from Google
Our collaboration with UNL has started a year ago as we were searching for a Frontend Developer for one of our projects. Apart from the fact that they helped us to find a really good and knowledgeable specialist, we also enjoyed our end-to-end collaboration. UNL team was always responsive, flexible, and highly professional, whether it was related to interview process or ongoing topics like invoicing, regular feedback consolidation, etc. We would definitely consider using their services in the future again.
Jan Tore Endresen's Review Sourced from Google
UNL contacted us for more than a year ago and offered us a development team to drive the development of an Asset Management application based on Google Cloud and with a reactive native app for end users. We are happy to confirm the cooperation has been structured, efficient and constructive. UNL responds quickly, offers reasonable rates and speaks good english. We do recommend UNLs services to other potential clients./Jan Tore Endresen (CEO)ShareBike
Ramuelle Antonetti's Review Sourced from Google
The team at UNL Solutions worked on our project for over a year. They are professional, knowledgable and just a pleasure to have worked with. If you are looking to outsource your project, UNL Solutions is a great full stack software development house with Java, RoR and .Net expertise (of course for the back-end), UX/UI and all modern javascript frameworks for front-end. We visited them in Loughborough and left with a very good impression of their outfit, their employees and their leadership. Highly recommend. A++++ experience.

Marabout's Review Sourced from Google
I worked at this company for a shot period of time and the review posted by former client is 100% accurate. Most of the people I met are super cool and many are super-talented. But the soft and managerial skills at the management level is not conducive of success, unfortunately. In the end, I realized how lucky I had been in my career so I was grateful for the eye-opener.
DC Drone Pilot's Review Sourced from Google
My development staff worked with HappyFunCorp over a multitude of times over the last year and their experience was that communications and the relationship on HFC's side was being conducted in an unprofessional manner compared to other providers we have worked with in the past several years of launching our newest venture.Due to these prior experiences, we have decided to cut our professional relationship with this software developer permanently. We we referred to them by another client, and at first we thought there was synergy, but that no longer seems the case as HFC is no longer following their values that at one time made them an industry leader.We will seek other options and there are far better developers our there for those seeking an alternative. We suggest you do your due diligence before contacting this firm. How this firm conducts business is critical to your success, so do yourself a favor and consider other solution providers.
Brett Edgerton's Review Sourced from Google
This company, according to industry insiders, is now insolvent. There are several posts and discussions about this once awesome company for software development, that is now working through how to deal with the bankruptcy.We have had several colleagues that have attempted to contact this company, only to be told they are no longer accepting new projects due to financial constraints and need to reorganize.
