      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.
