      Cross-Platform Review from Kristine Wilson

      I've been working with AllianceTek for over five years, and they have been an invaluable technology partner. They seamlessly took over a complex project from previous vendors and have since played a crucial role in managing both our app and website. Their team is highly knowledgeable, resourceful, and adaptable, with expertise across various platforms. No matter the challenge, they approach each project with patience, professionalism, and a problem-solving mindset. Their ability to listen, provide clear solutions, and ensure smooth execution has made them a trusted extension of our team. Beyond their technical capabilities, what truly sets AllianceTek apart is their commitment to client success. They are responsive, proactive, and consistently go above and beyond to deliver results. I highly recommend them to anyone seeking a reliable, skilled, and collaborative development partner.

      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.

      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.

      In addition to building out a native remote inspection app for iPads, Zco concurrently ported the software to a Xamarin platform for Windows users. Zco has released nine major iterations of the iPad app, each available in the App Store, as well as the initial version of the cross-platform Xamarin build. Their nimble team boasts a wide breadth of skills to match any given situation. Having clear documentation upfront has reduced onboarding time.
