Start from your situation, not the feature list.

You have QA capacity but no automation yet
Your testers know the product. Plain-language authoring turns that knowledge into a suite without hiring automation engineers first.

You have tooling but not enough people to operationalize it
The licence isn't the constraint, the headcount is. Embedded engineers arrive already automating and carry the platform with them.

AI spend is up but delivery speed isn't
The tool choice may not be the bottleneck. We assess against your delivery data, consolidate the tool pile, and transfer the capability back to your team.
