      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!

      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.

      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 recently engaged iTelaSoft to help us launch a new financial services product. iTelaSoft were able to quickly assemble a team, process and refine the requirements with us, and tender a solution with costings. iTelaSoft integrated with our team effectively to deliver the solution as specified with little issue, and post implementation support was great. I would work with the iTelaSoft team again on future engagements.
