WordPress Website Design Review from Lauren Maffei Johnson
Our company had such a wonderful experience with this team! Their design work is top-notch, and they did a really wonderful job of walking us through the process, but also finding ways to go above and beyond with things we needed additional help with, such as connecting Google Analytics. Highly recommend and would use again.

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.

Designli Reviews & Testimonials

Software Development Review from Anshuman Yadav
Designli created a clickable Figma prototype for the MVP of our AI-powered operating system, along with a detailed technical document for building it. As a founder, having something real to show made it much easier to validate the idea with potential customers and present it to investors. The team acted quickly on feedback, communicated proactively, and kept the project on schedule. Pairing design with technical planning gave us a clear path from concept to build.

Software Development Review from David Williamson
We brought Designli in to turn our construction management software idea into a clickable MVP prototype, complete with designed screens and user stories showing how the platform will work. They delivered on time and beyond what we expected. People in the construction industry who tried it were impressed by how simple and easy to use it is, even though the product behind it is complex. Communication was quick and clear, and the project was well managed throughout.

Mobile App Development Review from John Laporte
Designli helped us define the requirements, features, and user experience for an app for our motorcycle organization. They produced technical documentation and a clickable prototype covering navigation, member tools, and safety features. They were responsive, delivered on time every time, and turned our broad concepts into something people could actually click through. The prototype got our stakeholders aligned, earned internal approval, and set us up for engineering, and working out design questions early should save us rework later.
