Bilberrry Reviews & Testimonials

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 Ari Bixhorn
Bilberrry’s work gave our new website improved performance, greater SEO flexibility, and pages that are much easier to build. They delivered everything on time and kept communication proactive throughout. Their strong project management, technical expertise, and responsiveness built real trust during the process.

Chop Dawg Reviews & Testimonials

Web Development Review from Jimmy Caldwell
Chop Dawg was the strongest development team I’ve worked with in 18 years of software implementation. They took our complex AI-powered senior placement platform and turned it into a functional marketplace with dashboards, business rules, CRM integration, and an AI assistant. The team listened, adapted, communicated often, and treated our vision with real care. The handoff had a few gaps, but overall, they delivered exceptional work.

Design Services Review from Nathan May
Chop Dawg delivered wireframes, high-fidelity screens, a logo, and Figma files while keeping each week’s work clear. They felt like part of our team, brought fresh ideas, and pushed back when needed. The experience was strong overall, though a more detailed final review would have been helpful.

Web Design Review from Anonymous
Chop Dawg turned our early idea for a visual polling and decision-making platform into a prototype we could confidently share with others. It made the product much easier to explain, gave us something real to test with users, and supported more productive investor conversations. The work also helped our team get aligned on the product direction, development scope, and MVP roadmap. Their team was responsive, organized, and easy to work with throughout the process.

Collaborating with TRIARE company for the design and development of our online store was an exceptionally positive experience. Their streamlined processes and efficient project management ensured that deadlines were consistently met, and the project progressed smoothly. Communication was excellent throughout, with their team readily available to address any questions or concerns. They not only revamped our website's design but also developed it with precision and creativity. Their attention to detail and proactive approach to problem-solving were evident at every stage of the project. I definitely can recommend TRIARE!

Mobile App Development Review from Jonathan Fruitman
We thought that their proposed milestones were ambitious. I remember being pleasantly surprised after the first demo. Perhaps based on previous experience, my expectations were too low, but the team really did deliver on a consistent basis.

The app functions smoothly, with bugs or issues promptly addressed by TRIARE. With over 100,000 downloads, Apple has invited MindZip to participate in selected workshops. Overall, Triare met MindZip's expectations. (Verified via email)
