      PPC Review from Volodymyr Hadalin

      We were satisfied with the PPC services provided by the team. They took the time to understand our goals, set up the campaigns carefully, and communicated clearly throughout the project. The campaigns helped us improve the quality of traffic and generate more relevant inquiries. Overall, the collaboration was smooth and professional, and we would be happy to work with them again.

      SEO Review from Vlad Komovich

      We hired Elit-web to promote our project in several regional markets where competition was quite aggressive. They took full responsibility for market and niche research, providing us with detailed technical documentation, a well-thought-out backlog, and visualization of user journeys. What I especially liked was their approach to priorities. Elit-web didn't try to cover everything at once. They helped us identify the most important tasks, focusing on our long-term business goals, not just technical indicators. It felt like the team was genuinely interested in the success of our product, and not just closing another task.

      PPC Review from Daria Hlavcheva

      Elit-Web helped us take our PPC campaigns to a completely new level. They very quickly understood our goals, prepared a clear strategy and launched advertising, which began to yield results from the first weeks. I was especially impressed by how the team combines classic PPC experience with AI tools. Communication was easy and transparent: regular updates, clear analytics and quick reactions to any changes. We received more quality leads at a lower cost, and cooperation was as comfortable as possible.

      Software Development Review from Michael Meyer

      We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

      Web Development Review from Lathan Ashton

      RichestSoft was tasked with taking our existing templates, upgrading them to the latest version of our CMS, and deploying them to a staging environment. They also updated the designs for all subsections of the site. The site is fairly generic, consisting of static pages with links from the homepage to product descriptions, case studies, and more. Our team can easily log into the CMS and update case studies without needing a web developer, which has been a huge advantage. Our primary concern was the seamless conversion of our old templates, and RichestSoft handled this flawlessly. They even suggested ideas like making the site multilingual, though we only needed an English version, so it wasn’t necessary in our case.

      The website now has a more modern and appealing feel, and we've noticed an increase in the number of visitors since working with RichestSoft. They effectively leverage their technologies, and their communication and timeliness have been satisfactory throughout the project. Our business is centered around land development and industrial projects, supported by a team of IT professionals that manage the technology driving our operations. Our mission is to provide quality and satisfaction by utilizing our knowledge, experience, and ambition to meet and exceed our clients' expectations.

      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.
