Challenge

Two weeks before launch, an AI meeting product had no QA at all. Nobody had checked it outside the developers' own machines and browsers.

What we did

We ran exploratory testing across user roles, devices and browsers, and checked AI transcripts and summaries on real meeting recordings. We triaged bugs with the team daily and retested every fix before release.

Result

We found 60+ bugs, 15 of them critical, and all were closed before release. The product launched on schedule with zero critical defects afterwards.
