OpenC3

OpenC3 provides an open-source command and control platform for telemetry, commanding, automation, and dashboards for space and test. In practice that means building software for you when nothing off the shelf fits.

Who is it for? Mostly companies with a specific process to automate. Alongside the main category they mention 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.

OpenC3 is based in Erie, Colorado. You can read more at openc3.com.

Things worth asking about: portfolio relevance, who owns the code, and how they handle changes. A short pilot with your real data tells you more than any demo.
