About us

With our QA and software testing expertise, we help companies prioritize, plan, and design their QA processes, ensuring long-lasting quality and driving successful business outcomes.

Enhancing your software development journey

Putting quality in the agenda 

We live in a digital world where technology is not just a support but an essential tool for enhancing our daily lives and propelling business growth. Recognizing and addressing user needs is thus crucial to ensure quality in the applications your audience relies on daily. Quality is, at the end of the day, defined by the user’s expectations: performance, reliability, speed, responsiveness and beyond. 

Guided by this principle and strengthened by more than 25 years of experience in software testing and quality assurance, we empower you with the competence, expertise, and guidance needed to support you through each stage of your software development: from requirements to delivery. By staying ahead of technological advancements, industry trends, and organizational strategies, we proactively ensure that your software, systems, and apps not only meet but exceed user expectations. 

Our vision

...Through expertise and continuous improvment.

We are focused on being a driving force in shaping the quality of future products, services, and experiences. Anticipating future needs, staying ahead of industry trends, and actively contributing to advancements that will define the standard of quality in the years to come.

Our beginning

In 1998, ACIAL was founded and opened its Paris office, marking the company's first milestone. Growth in the French-speaking market followed with new offices in Nantes, Geneva, Lille, and Lyon, bringing us closer to our clients. In 2013, we expanded our services by establishing the Testing University.

Paving the way for future growth with QCENTRIS

In 2011, another milestone was reached when QCENTRIS opened its doors in Switzerland and Germany.

Borders were no limitation. In the following years, we expanded internationally, establishing offices in Austria, Egypt, Sweden, and Ukraine, allowing us to offer our services globally.
