      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.

      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.

      Jonathan Lopez's Review Sourced from Google

      A few years ago, I reached out to Heral for custom Mailchimp newsletter development based on AnnexCore's great online reviews in addition to their Mailchimp expert accreditation. He was a pleasure to work with, very professional, and even finished the job early with no revisions necessary.I refreshed our newsletter a couple weeks ago and then contacted Heral to execute the project. He responded to me right away, started the task immediately and completed the project ahead of schedule once again. This design was slightly more complex than the previous one, so Heral consulted me on a few issues to remedy a minor issue I had with the design. It was another great experience working with Heral and Annexcore. I recommend AnnexCore and Heral for any email marketing consulting and will definitely be using them in the future.

      Software Development Review from Vladyslav Sorochan

      A true tech partner who just gets it! Aqe has brought our rough software concept to life and turned it into a smart platform. The project covered everything from custom development to AI features and some pretty advanced data engineering. From the beginning, their team really took the time to understand what we were trying to achieve. They started with a clear discovery phase and built a solution that checked all the boxes in terms of functionality and ease of use.It is easy to work with their team, not only in terms of technical skills but also in how responsive and collaborative they are. They regularly improved features based on our feedback as we moved along and were always available when we needed support, even after the post-launch. Having that kind of ongoing help made a big difference.The results were a bit better than we expected. We saw a noticeable drop in manual work, smoother internal operations, and improved decision-making through real-time data.Overall, Aqe and their team really delivered what they promised, on time and within our budget. The whole experience was smooth, professional, and well-managed. Wed happily recommend working with them.
