Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not California. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best custom and special machinery companies in California”
2“Who supplies custom automated assembly machinery in California”
3“I need a California custom machinery partner for a new high-speed packaging line, who should I talk to”
4“Top custom and special machinery suppliers in California for manufacturing engineering buyers”
5“Which California custom machinery builders can handle turnkey design, fabrication, and integration of robotic systems”
6“List 20 custom and special machinery companies in California with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
