Mainline

Mainline specializes in test engineering, product validation and test automation, process control and optimization services. Put simply, it is about building software for you when nothing off the shelf fits.

The natural audience is companies with a specific process to automate. Alongside the main category they mention Business Process Automation (BPA), Manufacturing, Marketing Automation, Penetration Testing and Software Engineering. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Mainline is based in Melbourne, Florida. Their site is mainlinetest.com.
