# What each kind of source gives you

> Where segment revenue can come from, and what each kind of source leaves to you.

This table is about kinds of source, not products. The row for numi is the one you can check yourself with a sandbox call. The other rows summarise what the research found in the sources it read on 2026-10-29, and a product of a kind can differ from its row.
