      This is Roshan, CEO at NanoTherapX. Working with Probey Services for our CRM Development. What stood out most was their stability, consistency, reliability, and a smooth implementation.

      What stands out most about Probey Services is their discipline-no missed calls, no vague timelines, and no surprises.

      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.
