ZERO NEGATIVE Reviews & Testimonials
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.

Web Development Review from Sofia Juan
We recently had the pleasure of working with Small Projects Bureau Development on our new website for Show Kids, a company offering performing arts classes and after school programs for children in NYC. From start to finish, the experience was amazing.The team at Small Projects Bureau Development truly understood our vision and was able to bring it to life in a way that exceeded our expectations. Their creativity, attention to detail, and technical expertise resulted in a beautifully designed, user-friendly website that perfectly reflects the essence of Show Kids. The website is not only visually appealing but also functional and easy to navigate, which is crucial for our audience of parents.Throughout the process, they were communicative, responsive, and highly professional. They took the time to understand our specific needs and ensured that every element, from the layout to the content, was aligned with our goals. The final product showcases their commitment to quality and their deep understanding of web development.We couldnt be happier with the outcome, and were excited to share our new online presence with our community in NYC. So much so that we are now working with Small Projects Bureau Development again to create a new website for our upcoming location in Barcelona, Spain. If you're looking for a team that combines creativity with technical skill, we highly recommend Small Projects Bureau Development!Thank you for helping us bring Show Kids to life online, both in NYC and soon in Barcelona!
