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.

Danny Courtis has been exceptionally helpful and patient as he teaches me how to do my own google ads. He clearly knows all the ins and outs of the platform! I love getting targeted advice specifically for my situation, and that's what Danny is doing for me. 10 out of 10 - couldn't ask for a better teacher!

Anna DeBattiste's Review Sourced from Google
Danny from Somar Digital recently gave a presentation on Google ad grant management to a group I'm part of and it inspired me to set up an exploratory session with him. He gave me an hour of no-pressure, educational one-on-one time to explain how Google ad grant management works and what my opportunities might be. I was impressed with the quality of his service.

Gene McCreesh's Review Sourced from Google
FIVE STARS!!! 10 out of 10.After more than 30 years in business, I’ve learned the hard way that not all website and SEO companies deliver on their promises. Over the years, I’ve hired multiple companies that talked a big game but never produced real results.Nowadays, having a strong online presence is absolutely critical in the service industry, and Jeremy at Digital Minds has finally gotten us moving in the right direction. From day one, he’s been honest, knowledgeable, responsive, and incredibly easy to work with. He always answers the phone, knows SEO and website marketing inside and out, and consistently over-delivers for a very fair price.What I appreciate most is that Jeremy isn’t trying to drain your budget with unnecessary extras. He puts together a realistic game plan and rolls things out the right way so you get the maximum return on your investment.I can honestly say I’ve finally found my SEO, website, and marketing team. Highly recommend Jeremy and his team at Digital Minds to any business owner looking for real results. 100%. I'm super excited to grow this area of my business with the support of people that know what they're doing.Thank you,Gene McCreeshPresidentMcCreesh Tree Service, Inc.

Jeremy at Digital Minds is fantastic. From start to finish, he was incredibly personable, easy to talk to, and genuinely invested in making sure everything turned out exactly the way I needed. His responsiveness is unmatched — every question was answered quickly and clearly, and he consistently went above and beyond to keep the process smooth. If you’re looking for someone reliable, professional, and truly customer-focused, Jeremy is the one. Highly recommend!

Dave Everington's Review Sourced from Google
We are so pleased we decided to work with Framework. From start to finish they have been so clear with timelines, possibilities and creative design. Even after the website went live we have worked with the team to make small amends which were turned around extremely quickly. Special mention for Phoebe who managed the project. She has been so helpful throughout.
