      eCommerce Development Review from Kelly Johnson

      Since partnering with Bilberry, we have seen a marked improvement in our websites stability and performance. Their team manages our backlogged issues with such efficiency that our monthly development spend has actually decreased. Estimates are consistently accurate, and we appreciate their proactive communication; if a projects scope evolves, they provide an updated estimate for approval before moving forward. Our monthly sprints are now seamless thanks to their reliable planning and ability to scale resources rapidly to meet even the tightest deadlines.

      Web Development Review from Adam Ely, PMP

      As Director of Operations at Sands Investment Group, I partnered with Bilberrry to lead the redesign and rebuild of our website, enhance our marketing operations, and streamline internal workflows. We chose Bilberrry for their strong technical capabilities, cultural alignment, and outstanding reputation. The project followed a well-structured four-phase process: discovery, design, development, and launch. From the beginning, Bilberrry took a strategic and collaborative approach, conducting workshops and technical audits to define a scalable architecture and intuitive user experience. Their team went on to create custom designs for more than 20 pages, build a flexible design system, and ensure the site met key standards for SEO and accessibility. On the development side, they customized a robust content management system tailored to our needs, incorporating dynamic listing features such as saved searches, email alerts, and early-access content for select users. The new site also connected seamlessly with our internal tools, enabling greater efficiency and automation across teams. The impact was immediate and significant: we saw a dramatic reduction in manual processes. Our team is now better equipped to manage content independently, while the platform itself is built for long-term scalability and performance. Throughout the process, Bilberrry was responsive, professional, and incredibly easy to work with. They communicated clearly, incorporated feedback quickly, and consistently brought thoughtful, strategic ideas to the table. Bilberrry's unique blend of strategic insight, technical depth, and design acumen made them an invaluable partner in creating a high-performing, visually polished digital platform tailored to our business.

      Web Design Review from Alyssa Brenke

      Specifically, working with Ben was amazing! He was incredibly responsive and answered all my questions throughout the process of updating our website. Our original site was built roughly a decade ago (or longer) so we were in need of some streamlining and modernization. The team did just that and quickly! The first iteration was spot on for what we were looking for. Not to mention, they were able to launch quickly and without any interruption to our daily operations. Would 100% recommend [it]!

      My experience working with CouveCreative has been excellent. The full scope of our work together included a complete website redesign, a transition to new hosting, and ensuring an A level security scorecard...they handled each part with professionalism and attention to detail. Communication has been clear and consistent, and the team has been friendly, knowledgeable, and quick to respond to questions or changes throughout the project. I also appreciated their willingness to go above and beyond, even taking the initiative to learn and install a new tool simply to help troubleshoot an internal on premise issue on our side. We will be continuing our partnership with CouveCreative, and I feel secure and confident that any future needs or issues will be addressed with the same level of responsiveness and care. It has truly been a pleasure partnering with your company.

      Doron and his team are amazing! One of the things I spoke to Doron about when first meeting him was my desire to understand the overall structure of SEO better and I asked him if he would be willing to A. Start with a baseline of all the metrics of where our website currently was for future comparison and B. To explain to me in layman’s terms what he was doing when we met at the end of every month to discuss the results. He agreed with no hesitation and so far has been a huge help in increasing my understanding of SEO and also with huge results! Our company brand is very important to us and Doron has been very cognizant of that and has consistently tried to match the feel we are looking for in his website design and blogs. Doron and his team have almost tripled my website viewership in the span of six months, brought us to #1 on several search terms and in the top three for several others as well as increasing our google business clicks by over 300% in 5 months! Any minor technical issue that comes up he deals with swiftly and efficiently. I highly recommend him, he’s awesome!
