Great job! My wife and I liked both website design options you provided, but the first option was the clear winner! That's definitely the look I was going for on my new site!

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.

RNO1 Reviews & Testimonials

UI/UX Design Review from Neil Serebryany
I had the pleasure of working with RNO1 on a web transformation project in CalypsoAI and couldn't be happier. Right from the start, it was clear that they had a very skilled workforce, that had data architects as well as UX designers on board.They gave us a first implementation of your platform to work before your deadline and this demonstrates that they are conscious of time and the quality they want to offer. The look and feel design talents of RN01 are on par with the finest User Interface design and UX skills, moreover, the backend programming is also excellent.Most noticeable was their ability to fit into our working environment and improve the efficiency of our team while advancing the projects. Well done and organized they ensured the entire period was smooth and productive.As for web design and CMS development, I have no reservations in recommending RN01. They can really be considered as an innovation partner.
UI/UX Design Review from DANIEL HARMAN
The entire team at RNO1 was instrumental to the successful launch of our Product Management Company. Through the team’s guidance, design direction, and ease of working them as a Global Branding & Digital Agency.
