CSA

CSA offers services in system engineering, safety analysis, simulation and fault isolation through its software and tools. The job it does: building software for you when nothing off the shelf fits.

It makes the most sense for companies with a specific process to automate. They also list Simulation and Software Engineering, so expect those to show up in the feature set. 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.

CSA is based in Adamsville, Rhode Island. Their site is csa-usa.com.
