Zealous System Reviews & Testimonials
Grzegorz Grabczak Chief Executive Officer at DIGITAL-IMAGES
5.0★
Software Development Review from Grzegorz Grabczak
We worked with Zealous System on an AI-powered fraud triage solution for one of our clients in the Europe financial services sector. The project involved a complex fraud investigation workflow where analysts were handling a large number of alerts and gathering information from multiple systems. Zealous System worked closely with us to understand the requirements, existing processes and expectations of the end client before moving into development. The team developed an AI-powered fraud triage agent that brings relevant information together, helps prioritise alerts and provides explainable recommendations while keeping human analysts involved in important decisions. What I appreciated was the team's ability to understand both the business and technical sides of the project. Communication was consistent, and they were responsive when requirements evolved during development and testing. The solution helped streamline the investigation process and reduce the amount of repetitive manual work involved in reviewing fraud alerts. Overall, we had a positive experience working with Zealous System. They were a reliable technology partner for us on this project, particularly given the complexity of introducing AI into a financial services environment.

DIPAK VAIDH's Review Sourced from Google
I visited Zealous System on 16th June 2025 for the walk-in interview announced on LinkedIn for interns/freshers in Python, PHP, WordPress, .Net, and QA roles. Despite clearly stating it was open for freshers, upon arrival, all Python candidates, including myself and my sister, were told they only accept those with prior experience, as interns are directly placed on live projects. This information was never mentioned in the post. The company blamed the marketing team for the misleading post. This experience wasted our valuable time, energy, and travel expenses. I urge the company to coordinate better internally and post accurate job/internship information to avoid misguiding freshers who genuinely seek opportunities.

Zealous System is outstanding when it comes to AI development! Their team helped us build a smart, AI-powered software solution that completely transformed how we manage data and customer interactions. They explained complex AI concepts in simple terms and delivered a solution that works flawlessly. From planning to post-launch support, everything was smooth and professional. Highly recommended if you're looking for reliable AI experts!

Kelly Lavelle Founder, Chief Beauty Officer at Aloe Beauty

Software Development Review from Kelly Lavelle
We hired Competenza to build a custom software tool to help manage our online bookings and product sales in one place. They designed and developed a booking system for our spa that also connected with our product store. It included custom dashboards, easy scheduling, and reports we could actually use. We saw fewer booking errors, faster checkouts, and more online sales. The system saved our staff time every day and made things easier for our customers too. They really listened to our needs and built something that felt like it was made just for us, not a one-size-fits-all. Everything was done on time and the process was smooth. Communication was clear, and they were quick to make changes when we asked.

Software Development Review from Bahaa Wahid
Competenza Innovare upgraded our platform with better video, new connection options, group ordering, and a catering tracker. They worked in clear sprints, tested across devices, and delivered on time and in budget. The backend and admin site they built make managing content easy. Communication was consistent, and they were quick to fix issues. Very organized team.

Software Development Review from Brett Danielson
They built a custom search tool for us. The system works well and saves us a lot of time. They keep up with our fast pace and still hit deadlines. Sometimes they even add features we didn’t request because they know it will help. Now we can look up customer info, shipments, and vendor details in seconds. We meet every week to go over what we need next. They fix bugs, but they also make the system easier to use without us asking. Our business changes fast, but they stay patient and flexible. They really listen and adapt. Everyone on their team wants to help us succeed.

Linda Jane Review from Google

Linda Jane's Review Sourced from Google
Our startup idea is quite complex because it solves some of the most challenging problems in the fintech industry. This idea requires a product that not only leverages the power of Al (LLM) but also incorporates cutting-edge technologies like RAG (Retrieval-Augmented Generation). It was very challenging to find a team with firsthand experience in all these advanced technologies, but we found Sunrise Technologies. They are one of the few companies in Australia capable of solving the most complex tech problems.

I'm currently working with Sunrise Technologies to build a mobile application with an integrated AI agent. Before choosing Sunrise, I spoke to many mobile app companies in Sydney, and I can confidently say my decision has been well rewarded. The journey so far has been excellent and Sam and the team have gone above and beyond to meet my needs. I’m happy to recommend them to anyone looking to build software products. 5 stars from me

I have worked with the Intuji team (formerly WEBO) on several integrations since 2022 and have found them a pleasure to deal with. Dilshad and his team of experts and good at what they do, and I continue to place my trust in their technical expertise and support. Whatever technical issues arise, they are always happy to assist to their best ability. Would highly recommend Intuji to any business/company seeking expert digital support.

Julian and his team developed a website from nothing and the outcome was above and beyond our expectations. The team at WEBO Designs has continued to offer assistance and support throughout our initial and ongoing marketing campaigns. WEBO Designs not only have a great understanding of web development and marketing, but also assisted us with hosting services for emails and a number of other IT elements. We enjoyed our experience working with WEBO and look forward to working with them in the future.

We made the decision to move our development back home, after years of working with offshore developers. The Mobi team made the transition seamless, coming up to speed on a complex auction system quickly so there was limited down time in development. Mobi doesn't feel like an agency partner, but part of the FarmGate team. They aren't afraid to speak up if they feel we're heading off course, advise us on the right technology partners and have worked through the night alongside us if s%#t ever hits the fan. We know they have our back!
