      Web Development Review from Jaroslav Tyman Jr.

      We contacted Zero Negative about a two stage renewal of our company website with a very aggressive timeline for the first stage. Zero Negative worked and guided us through pulling off the first stage within our timeline while also ensuring that the content and ideas for that stage were readily applicable to the full design. When we got to the full design, they were fully responsible for corralling the various preferences and ideas from our team into a well executed cohesive site. We're now in a good spot and look forward to continuing to work with Zero Negative as our business and needs grow.

      Web Development Review from Susan E. Roberts

      Zero Negative did an exceptional job designing my website, roberts-communications.com. From the start, they understood that this wasn't just about aesthetics it was about positioning, credibility, and clarity for a senior-level communications brand. They translated a complex, high-stakes business into a site that feels polished, modern, and authoritative without being flashy or over designed. The process was collaborative, efficient, and thoughtful, and they were responsive to feedback while also offering smart guidance when it mattered. The final result reflects exactly how I want Roberts Communications to be perceived: strategic, sophisticated, and trusted. I would highly recommend Zero Negative to anyone looking for a design partner who understands brand, not just web building.

      Web Development Review from Anonymous

      These guys are the best! We engaged with Zero Negative to develop a comprehensive web-based system for our factory that allows for managing orders, processes, and inventory. This initiative was essential for us to secure a big ticket client. We truly could not have accomplished this without their assistance. They dedicated considerable time to on-boarding and collecting the requisite information, followed by prototyping the software, and ultimately developing it from scratch. Overall, we are very satisfied.

      Solveit managed our comprehensive eCommerce project, developing a full-featured web platform with Node.js and React technologies. The agency also created a Flutter-based mobile app for seamless data synchronization across iOS and Android devices. We were thoroughly pleased with Solveit's expertise and adherence to deadlines. It provided timely updates and communicated openly about our project's status. Solveit's proactive approach and transparency were exceptional, particularly during the staff augmentation process, where the agency efficiently matched us with qualified candidates and facilitated a smooth onboarding. We were satisfied with Solveit's high-quality work and exceptional support.

      iPhone Review from Gabriel Sabadin

      We engaged SolveIt to develop a minimum viable product (MVP) app, including a user-friendly iOS design, an artificial intelligence (AI) model, and a monetization strategy while ensuring General Data Protection Regulation (GDPR) compliance and preparing for future integrations. Despite a tight deadline, SolveIt delivered the app on time and efficiently handled beta-testing within three months, allowing us to gather feedback and launch successfully. We acquired our first 1,000 users within a month of launching the app. SolveIt's team communicated effectively, addressed issues proactively, and maintained a high level of autonomy, bringing diverse expertise that greatly benefited our project. We appreciate the agency's dedication and professionalism.

      Product Design Review from Chris Milner

      UXReactor helped us with a UI/UX research process, which included in-person interviews where they walked users through unboxing, connecting, and using the features of our smart air conditioner. From there, the team took the findings and produced a report for us to make improvements to our app and increase our activation rates. In addition to the report, UXReactor also redesigned some parts of our app using Figma. The project required a very iterative process, so we required more than one discovery call to get started. In fact, they didn't just work with me; we also integrated our consumer marketing insights team to identify participants. We also collaborated with them to figure out how to recruit the right users based on our target customer profiles. Additionally,UXReactor recruited participants for us, going through their database to find actual users. Then, they brought a researcher and a designer to interview all the participants on-site in their location. That was actually a challenge because we're a remote team, but we needed a physical location to show the actual air conditioner to the participants. After the interviews, UXReactor worked with us to go through the results and the report's structure. We had multiple revisions to ensure that we were pulling out the insights I wanted to find on it. After the report was complete, they actually delivered it to our overseas team, doing a presentation that included the insights and recommendations.

      Product Design Review from Dhirendra Kumar

      The objective was to create a safety release which would activate at certain weights and fit into an already existing design. Porticos was able to create a strong, lightweight and reusable buckle which fit perfectly into the design both functionally and visually. Their involvement improved the overall safety of our therapeutic equipment, and allowed us to develop another complete product line of similar products with other applications.

      UI/UX Design Review from Kamil Qui

      The project scope was to to refresh the UX and visual design. The project lead really helped . I was taking care of a lot of other things, so I appreciated getting weekly updates from them. They detailed the work they did and then outlined the next items on the list. They brought up potential roadblocks in advance, making sure wed still meet deadlines. UXReactor worked very closely with us, so they were an extended team from my perspective. I could call upon and engage them in discussions, and we had daily standups. They followed a systematic methodology, and that helped us go through the process of doing user research, collecting feedback, and combining that with the existing product features. Using that, we were able to create a framework that allowed us to continue development.
