How the list is made
The list comes from Alion's similar-companies engine, the same one AI agents query through the Alion MCP server. A company ranks higher when it shares more of American Systems's industry segments and is less spread over others, when its job postings name the same technologies, when it is headquartered in the same country and when its size is close. The list is rebuilt every week.
