According to Pew Research Center, 83% of US adults were using smartphones in 2019, and 74% of them were also desktop or laptop owners. Moreover, surprising four and a half billion people around the globe, which is 59% of the total world population, were internet users.

With the use of technologies constantly increasing, users get picky — the more sophisticated they are, the more powerful software is expected to become. This contributes to an ever-intensifying market competition.

At the same time, providing customers with software that meets all the expectations is only half the battle: before and once the product is on the market, companies also have to take care of their up-and-running systems, as well as ensure the cohesion and integrity of the IT environments these systems operate in.

Why Do I Need Software Testing Companies?

The more intricate the solutions are, the more potential faults they are likely to carry. Not only this affects user churn rate negatively, but also results in reputational damage the product owners may face, with hardly predictable losses. According to the research by CISQ, poor software quality costed US companies approximately $2.84 trillion in 2018. That’s why it’s crucial for software providers to consider quality assurance and testing as thoroughly as the development process itself, and ensure the following:

  • The software performs well and precisely fits business specifics 
  • There are no security flaws, so sensitive data is kept safe
  • The software satisfies users’ needs and makes their activities effortless

Quality assurance is a complex time-consuming process, which should be entrusted to experienced professionals with relevant expertise. In case you are looking for such a tech partner, we’d like to facilitate this challenging task and provide you with the list of 30 leading software testing companies. 

When analyzing the market, Explority identified six criteria that served as the basis for evaluation: 

  • Online reviews
  • Market presence
  • Geographic strategy
  • Industry experience
  • Customer experience
  • Portfolio

Each provider is a unique company with both strengths and weaknesses, so you are welcome to find the perfect one for your needs and budget based on the scores below.
