Software that has to hold up in the real world
A demo is not a product. Real users, weak networks, and awkward cases are the job.
We test paths that do not appear in a slide: retries, empty states, permissions, and devices that are not the designer’s laptop. Launch is a step in the process, not a surprise at the end.
This is why custom software, mobile apps, and web applications share one philosophy at RootoverZero. If it only works in a staged environment, it is not finished.
Businesses hiring a software company should ask how testing is defined. If the answer is only visual QA, keep looking.
