Chop Dawg Reviews & Testimonials
Jimmy Caldwell COO at BedMatch Pro
4.8★
Web Development Review from Jimmy Caldwell
Chop Dawg was the strongest development team I’ve worked with in 18 years of software implementation. They took our complex AI-powered senior placement platform and turned it into a functional marketplace with dashboards, business rules, CRM integration, and an AI assistant. The team listened, adapted, communicated often, and treated our vision with real care. The handoff had a few gaps, but overall, they delivered exceptional work.
Nathan May Founder at Undisclosed
4.7★
Design Services Review from Nathan May
Chop Dawg delivered wireframes, high-fidelity screens, a logo, and Figma files while keeping each week’s work clear. They felt like part of our team, brought fresh ideas, and pushed back when needed. The experience was strong overall, though a more detailed final review would have been helpful.

Web Design Review from Anonymous
Chop Dawg turned our early idea for a visual polling and decision-making platform into a prototype we could confidently share with others. It made the product much easier to explain, gave us something real to test with users, and supported more productive investor conversations. The work also helped our team get aligned on the product direction, development scope, and MVP roadmap. Their team was responsive, organized, and easy to work with throughout the process.

5.0★
UI/UX Design Review from Neil Serebryany
I had the pleasure of working with RNO1 on a web transformation project in CalypsoAI and couldn't be happier. Right from the start, it was clear that they had a very skilled workforce, that had data architects as well as UX designers on board.They gave us a first implementation of your platform to work before your deadline and this demonstrates that they are conscious of time and the quality they want to offer. The look and feel design talents of RN01 are on par with the finest User Interface design and UX skills, moreover, the backend programming is also excellent.Most noticeable was their ability to fit into our working environment and improve the efficiency of our team while advancing the projects. Well done and organized they ensured the entire period was smooth and productive.As for web design and CMS development, I have no reservations in recommending RN01. They can really be considered as an innovation partner.

MaryRuth Ghiyam Founder at MaryRuth's

Mobile App Development Review from MaryRuth Ghiyam
Kaizen Apps is developing a mobile app for us. We provided information to jump start the project, and they gave us samples of similar projects they've done to give us an idea of what to expect. They provided a detailed scope of work that was over 100-pages long. We had several exchanges back and forth to tweak requirements for a few weeks. Our respective lawyers also looked over the scope. After the scope was approved, the team got into the project launch and began the design phase. The team started with a low-fidelity design and built swim-lanes. After that, they moved into high-fidelity design, which they're about to finish.Additionally, the Kaizen Apps team provides us with consultancy services to help us grow the app. For example, they've advised us on handling customer service and tools we can use to help with that aspect. They've also connected us to other parties that can help us.

Web Development Review from Vadim Kagan
Our company hired Kaizen Apps to develop our site backend database and front-end. They did a fantastic job. The site was fully coded, from start to finish. It wasn't on WordPress, wix, etc. It also needed to contain a database. There were so many guidelines to follow that I was impressed that each was fulfilled with ease. I was impressed by the ability of receiving a fully working site and also having received SEO & Google Ads setups. An all-around company.
Kenneth Barrett President at Flint Technologies Solutions

Web Design Review from Kenneth Barrett
Kaizen Apps provided a full redesign of our website and recreated it in WordPress in a fashion where we can easily make changes without them. Website redesign included homepage development, some coded items to reflect our framework, design ideas to display unique value propositions and many solutions page. The team was responsive and delivered in a timely fashion when we wanted launch to be beginning of the year. The website redesign as offered us a fresh look to reflect our updated solutions/services. It has also helped us on the backend to easily make some changes ourselves.The quick-turn around on requests and design items. Also Kaizen Apps availability to hop on a call - which at times was late at night when we were trying to meet a deadline. Very flexible and their team was committed to pulling it which exceeded my expectations. Kaizen Apps is also very clear on what is feasible, what is not, and price points accordingly - straight shooter - which was very helpful as we were developing ideas.

Tony Greco Review from Google
5.0★
Tony Greco's Review Sourced from Google
TDF provided us with product management, development, and strategic consultation. We started to build the product with an individual and had initial wireframes and mock-ups, but the project quickly grew larger than an individual person could handle. TDF evaluated what we had and gave us feedback, then created a plan to replace and fix what had already been done. They started with extensive customer development-- something we missed the first time around-- so their new wireframes and plans were based on what our customers actually wanted. Then, they executed the plan.In addition to the development work, they also took care of logo and design work. They used Amazon Web Services for our platform. We have multiple features such as an API, database, and an administration tool for our own interface. We have a provider tool for facilities to update their data within the database. People can find resources on our web page, web application, and an iOS and Android app. We continue to work with them and have found it more effective and efficient to use them as a virtual outsourced department.
Tom Goddard Review from Google

Tom Goddard's Review Sourced from Google
We are a consulting firm that specializes in working with healthcare organizations who are seeking to become accredited, stay accredited, or are working with particular healthcare legal compliance issues that we specialize in. The management of a typical accreditation process is complex for both the applicants and consultants providing them with help, so we wanted technology to help simplify and clarify that process.The Development Factory developed and designed two important pieces of software for us that have gone through multiple iterations over the years. The most important is an online project management platform that has all of our resources in one place and allows us to have secure communications with our clients and exchange documents and feedback important to the accreditation process. The platform also provides dashboards for our clients that allow clients to track their process and see how they're doing based on our scoring system that scores any documentation that will be sent to accreditation organizations.The second piece of software TDF built is a training program called AccrediTrain. We had a training software before, but they built a new self-service version that is completely automated, allowing a client to schedule a training for their employees without having to involve any of my staff.As a result of the work TDF did for our firm, we are now able to handle a larger number of clients with the same number of staff, helping us to increase our revenues by a factor of four.Beyond that, the reactions to our platforms have been outstanding. Just recently a new client was having her first experience with Goldfinch and she said it was just amazing. Another client of ours is a competitor and asked us for help on a project. This is an organization that has a particularly sophisticated knowledge about the accreditation process, and their CEO and president was very impressed by our software platforms.They really listened to our description of what we do and how we do it and then turned that into software that quite beautifully captures what we do and how we do it. They clearly care about us and our satisfaction.

AppMakers USA Reviews & Testimonials
Yaakov Babani Manager at Growth Co.
5.0★
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.

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.
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!
