Get in touch with Vasyl to discuss your quality assurance needs and learn more about our services.


Do I need a quality assurance partner?

The short answer is yes. If you don’t have a solid quality assurance process in-house, you need to partner with a QA services company that can have your product or service tested before it reaches the market, as well as each time an update is implemented. With that in mind, here are a few more specific scenarios: 

  • You have a product that requires constant updates, something which makes regular quality assurance necessary to ensure high quality performance.
  • You have trouble hiring enough in-house QA engineers and are looking for external support to take testing off the shoulders of developers or project managers.
  • You don’t have a quality assurance process at all and want experienced QA engineers to set it up from scratch.
  • The first version of your product is already on the market and now needs an in-depth QA audit to ensure its fault-free performance in the next release.
  • You produce IoT solutions and lack the lab equipment required to cover embedded software QA services to test your products.
  • You lack a specific type of QA expertise for a project.
  • You’re looking to automate your quality assurance process.
What products can I test with you?

Our multifaceted team provides product development and quality assurance services for IoT devices, digital experiences, and products based on artificial intelligence.

This means the range of products and services we can test is expansive, from simple mobile apps and web-based systems to multi-layered integrations between apps, devices, the cloud, and embedded software. Simply put, if you see a service on our website that pertains to your specific product, you can be assured of proper QA.

Are there any other reasons why I should choose Lemberg Solutions over other providers of QA software testing services?

Effective communication. You’ll be in touch with our QA team at all times and receive regular updates on the testing progress. If you have any questions, you’ll be able to ask them right away.
