      Software Testing Review from Lindsey Allard

      They move really quickly which is huge for us as a startup. They are also very flexible. We added their team to our slack channel so now it’s so quick to ask them to test certain thing and they meshed with our dev team seamless.

      Software Testing Review from Maria Musillo

      Ongoing web application quality assurance testing including new features and regression testing. Additional penetration testing and site scanning. Ability to quickly assign a resource to a new project, little lead time needed. If a resource gets reassigned they do the handover on their end without being dependent on customer.

      Software Testing Review from Domoniq Doby

      QA Mentor has been an excellent on demand source for our immediate QA needs. Not only are they prompt and great at executing directions, they exceed expectations. They also have great integrity and are always responsive when needed, and not needed. I will continue to use them for my on demand QA services.

The team ensured the process was seamless and straightforward, which significantly minimised disruption. Their expertise and attention to detail gave us complete confidence in the solution delivered. The aftercare and ongoing support have also been excellent, providing reassurance that we are in safe hands.
