The Challenge
Sonar had a strong product but a confusing online presence. Their old site lacked clarity, hierarchy, and performance-focused UX. They needed a design system and content flow that communicated product value quickly, simplified technical language, and nudged users toward action — across both marketing and onboarding flows.
Our Solution
We started with a deep UX audit and restructured the site’s information hierarchy. Using a modular component-based system, we redesigned the entire web experience with an emphasis on clarity, white space, and mobile responsiveness. On the back end, we implemented performance-first development to ensure fast load times and CMS flexibility.


The Outcome
Following the relaunch, US Car Buying saw a 34% increase in test drive sign-ups and a 22% drop in bounce rate. Their new site positioned them as a premium, enterprise-ready solution and gave internal teams the tools to scale marketing with ease.
