Responsive design fails often happen because teams test only standard breakpoints, not real device variations.

Build a service that tests websites against actual viewport dimensions collected from real user data.

Design teams would pay to catch responsive issues before deployment.

Start with a simple testing tool that checks against common problem sizes.

The risk is competition from broader testing platforms.
