Fintech Review from Sergei Lishchenko
The exception team the client collaborated with brought in fresh ideas and innovative technologies previously unfamiliar to the client. For example, with Yalantis' guidance, the client's developers explore the Go language. The primary reason the client chose Yalantis is its strong organizational and project management skills. It's not just about the developers; Yalantis provides a comprehensive support framework, ensuring that a project manager is consistently present. (Verified via email)

UI/UX Design Review from Frank Duenas, MS
Slide UX has been such a pleasure to work with. The team deeply understands our needs and provides very thoughtful solutions, insights, and analysis. They intimately understand the uniqueness of our industry and our business objectives. I look forward to the next opportunity to work with them.
UI/UX Design Review from John Miller
We had the pleasure of working with Slide UX on a recent project requiring deep user engagement and thoughtful design. Much of this work was particularly tricky, as the workflows were for expert users in a complex system, and the focus was ensuring users can do their work quickly and with a high degree of accuracy.Their team expertly helped us conduct workshops to gather insights from end users, identifying pain points and refining complex requirements. Their ability to translate these discussions into clear, actionable designs and wireframes was invaluable, ensuring that the final deliverables were both highly usable and aligned with our needs.Beyond their technical expertise, Slide UX consistently demonstrates exceptional professionalism and responsiveness. They collaborated seamlessly with our team for about a year, maintained clear communication throughout the process, and consistently delivered high-quality work on schedule. Their keen eye for detail and ability to create a set of cohesive design elements across our larger application suite further strengthened the outcome. We highly recommend them to any organization looking for smart, user-focused design solutions.
UI/UX Design Review from Dane Koch
As a UX designer at SolarWinds, I had the opportunity to work closely with the team at SlideUX during the redesign of our company website, and I couldn't be more impressed with their professionalism and expertise. From the outset, their team demonstrated a clear understanding of our goals, offering valuable insights tailored to our business needs and our users' expectations. They consistently delivered high-quality work, providing detailed audits, wireframes, mockups, and site maps aligned perfectly with our vision. The professionalism and attention to detail were evident at every stage, making the entire process seamless and efficient.One of the biggest challenges we faced during the project was our evolving company strategy, which often led to shifting priorities and new direction mid-project. Despite these hurdles, SlideUX was incredibly adaptable. Their team not only met each new challenge with a solution-oriented mindset but also communicated proactively with our internal team to ensure that every change was integrated smoothly into the design. Whether it was refining the user experience for a newly prioritized feature or adjusting the visual language to better reflect our updated branding, SlideUX's ability to pivot while maintaining design integrity was invaluable.Throughout the process, SlideUX didn't just design for us they also took the time to consult with our internal UX team, offering mentorship and sharing best practices. This collaboration helped strengthen our own design capabilities and ensured we were aligned with modern UX standards. The final product is a sleek, modern website with a much-improved user journey that is intuitive, engaging, and aligned with our broader business goals. Thanks to SlideUX, we now have a user experience that not only looks great but also performs seamlessly, setting a strong foundation for future growth.

Ryan's team handled our Chicago company's WordPress redesign from start to finish, and the SEO groundwork was baked in from day one.

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.
Ravi Prajapati's Review Sourced from Google
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 highly recommend Isaac with Techy Toes! I’ve been blessed to have found Isaac and received his services to help promote our plumbing business in Arizona. Within the first 6 months of help Isaac not only had provided us with a fully functioning website but also had worked his magic in getting us to become visible on Google. We have held one of the top three spots in our city on Google Maps for the past 4 years now. The past three years we were awarded the best plumbing company in our city from 3 separate plumbing magazines. We would never have been able to accomplish what we have so far without Isaac. We highly recommend his SEO, Website, and other business related services. He is very honest, patient, and hard working. He will always receive our honor and gratitude for his dedicated hard work and patient understanding. Thank You Isaac and Techy Toes.
