GNU Radio Project

GNU Radio is a free and open-source software development toolkit that provides signal processing blocks to implement software radios. The job it does: solving a specific business problem with software.

It makes the most sense for teams in its space. Related areas on their profile: Non Profit. As a very small product team themselves (1 to 10 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

GNU Radio Project is based in Washington, District of Columbia. You can read more at gnuradio.org.

Things worth asking about: pricing, support, and how it fits with the tools you already use. Get the renewal terms in writing before the first invoice.
