What reviewers mention most
“Best”
This is the best place forever, they are very professional.
“Awesome, helpful team”
Zealous has worked with us closely to develop our app. They were always professional, patient (when we didn't know what we needed), and positive about the whole process. We had no idea what we were doing, most of the time - but the team at Zealous did ... and they made the effort to get us where we needed to be with their skills and expertise. I would highly recommend them.
“A world class class software development partner”
It gives me great pleasure to that Zealous is an amazingly reliable, trustworthy and talented company headed up by Pranjal, a Titan of his industry. Since dealing with Zealous, we have come leaps and bounds with our technology, their ability to produce world-class software has blown us all away and can only say good things.
“Azure Website”
I've been working with Zealous Systems for nearly 2 years and I'm very satisfied with their quality of work, communication and timely delivery. My experience with them has been primarily in Microsoft Azure, C# and ASP.Net MVC. I would highly recommend them.
“Working with them for years!”
For several years now, I have worked with Zealous and they have proven to be a valuable partner. They produce quality code, they understand what needs to be done, they communicate perfectly (excellent in English), and they respect timelines. They are a pleasure to work with and I fully recommend them.
“WP Website”
We a good feeling with Zealous from the beginning. They were very interested in the project and we felt that they understood the requirements to 100%. The offer was competitive and we were proven right with our decision during the project. The developers working on the project were capable and were also looking for improvements in the user flow. Finally we even had some changes to the original plan but were not charged for these additional works by Zealous. Even tough delivery took longer than expected we are very happy with the outcome and can highly recommend Zealous.
“Excellent Partner”
I was retained by a client as a Software and Cloud Architect to support internal and customer-facing products. The client had existing mobile apps of poor quality built by another provider. Zealous System was able to pull together a team that could understand the IOS and Android apps, and immediately begin making corrections and improvements. The Android app turned out to lack significant features. The Zealous System team was able to replicate these missing features along with the improvements introduced in IOS. The Zealous System team was very effective in communicating progress, raising issues, and working as a team. At the management level, Zealous System took on joint ownership of the client success and partnered well to work with some unique constraints. Zealous System is my go-to provider for expanding my team
“GOOD JOB”
It has been a pleasure collaborate with this team of guys for sure they do a good job
“Confident, Reliable Software Services ”
I have used Zealous for several of my projects, I have found the team to be very professional yet personable. When I work with Zealous, I know I am getting the best developers who understand my requirements before they start. What I love about Zealous, when they deliver a project, I don't have to give much feedback, they get it right the first time. This is a rare quality. Thank you Zealous.
“Flexible, Responsive, Great Value for Money”
The Zealous team are extremely committed, responsive and delivered a high quality output. I would not hesitate to use them again and recommend.
“Happy to recommend Zealous System ”
Looking to expand our business in Germany, Augustine Tours hired Zealous System to re-design our website. From the Project Manager to the Developers, they were so helpful : all our business needs were considered, a true bespoke customer service. Highly recommended.
“Faulty web development, poor client services, and poor attention to detail”
I hired Zealous Systems to handle a site migration for me and build membership site functionality for my Wordpress website. While they managed to migrate my data from my old platform successfully, including my podcast and content, they failed to execute the functionality agreed in the scope of work. The membership site coding they created for me kept breaking down, resulting in many of my clients and site visitors complaining about a confusing registration process that I flagged with Zealous again and again. They never managed to fix it, even after going back and forth about it with them for over 12 months. To make matters worse, they left most of the QA site testing with me, rather than taking the lead on ensuring no errors existed in their coding. When I did these checks, I regularly found sloppy errors, typos, and design flaws. Working with Zealous was hugely time consuming and a big waste of money. They also refused to acknowledge their mistakes even after the next team I hired summarised all the errors in their coding. I will never work with Zealous again, and I would recommend you steer clear of their company.
“Resource services”
We have hired professional services from Zealous Systems along with resource services and are more than happy as well as satisfied with the work delivered by them.
“Excellent service, very happy with the finished product. ”
Parth and Raj were always available for me and answered my questions in a timely manner. They understood what I was trying to achieve and delivered a website which I am very happy with. I will be using them again for other websites which I will be creating shortly. I would highly recommend them.
“Over delivered on my expectations 3 times”
This is my 3rd project with Zealous, every time I was surprised by the extra mile the Staff and Management would go to for me. I can 100% recommend Zealous for any Software or App development project.
