      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.

      Oyova has continuously proven to be a fantastic partner to our team! They are knowledgable, easy to work with, and come to the table ready to collaborate. When seeking a business relationship, the hope is always that it’s seamless, and that’s exactly the experience we’ve had with them. Whether we have a simple question or a complex need, they remain a team that we can rely on. My primary point-of-contact is Beth, and she’s been wonderful! She’s not only great at keeping things on track, she’s also kind and approachable. In fact, I’ve collaborated with multiple members at Oyova and everyone has made it easy to build a long-term, trusting relationship with them. If you have the chance, work with them. You’ll be glad you did!

      Small Businesses Website Development Review from Kris Meyer

      Austin rebuilt our website from the ground up and helped turn Bespoke Tint & PPF into one of the top tint brands in Bellevue. The work started with a full redesign of our website, including branding, copywriting, conversion improvements, mobile optimization, and development. The new site immediately performed better and generated more leads after launch. After the website launch, we continued working together on SEO, AI search optimization, paid advertising support, analytics, A/B testing, and ongoing marketing strategy. He also helped improve our review visibility, local search presence, and overall positioning online. What started as a website project became an ongoing growth partnership focused on increasing traffic, leads, and customer acquisition.
