      Mobile App Development Review from Sony Tiwari

      The whole Team at Calibrate have been great from beginning to end, and we're excited to have a partner as we continue to grow. Three words I would use to describe Calibrate are organized, insightful and collaborative. From the outset the scope of work was clearly defined, but they also showed great flexibility working through changes that arose. Faizan is terrific at running our regular meetings and keeping everyone up to date on progress. The team has a good balance at listening to your ideas but also guiding with their experience and expertise.Our project took longer than anticipated because of issues unearthed during the development, but Kevin and the team worked through it all with us. They went above and beyond to make sure we were satisfied with the final outcome.This is a talented team for sure, but their passion and ability to collaborate effectively is what really sets Calibrate apart.

      eCommerce Development Review from Lorien Yonker

      I partnered with Calibrate to develop a new eCommerce website, expertly integrating it with Shopify. Its guidance on software operation and website maintenance for future collections was invaluable. I valued the agency's patience and helpfulness in teaching me software intricacies and quick adaptability to changing project scopes. What set Calibrate apart was its attentive approach. Calibrate's small team was ideal for addressing my concerns proactively. While some may find it a drawback, I preferred the agency's primarily virtual meeting approach. (Verified via email)

      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.
