Our Story

Testlio was founded in 2013 by Kristel and Marko Kruustük after winning a global hackathon (AngelHack). The Techstars Accelerator in Austin then forged the Testlio product/service approach. By 2014 Testlio was serving clients, furthering the product, expanding a global tester community, and growing an amazing team. As the company picked up momentum, press, analysts, investors, and others took notice. Today, the company has raised ~$8.5M, is financially and operationally strong, and remains manically committed to the four concepts below.

We live to do four things:

First, we are passionate about advancing the practice and impact of QA work on a global scale.

Second, we are committed to enabling a massive community of testers around the world to flourish.

Third, we work tirelessly on our software platform to ensure it meets the highest standards.

Fourth, we partner with amazing app providers, bringing robust teams of professionals to serve them.
