How the list was made, and what we do with it
- Chosen by hand
- Every source is here because people who work in B2B SaaS & GTM say substantive things on it, not because it is large. Enough of them to cover the field, few enough to audit.
- Checked before listing
- Each feed is fetched before it goes on the list, and a feed that answers but has stopped publishing is a fail, not a warning. Every source is English-language and public.
- Read, so you need not
- You do not have to read all of them. Each new post is read, and the claims worth keeping are pulled out with a link to the paragraph they came from.
- Sent as a brief
- The 12 lines that rank highest across the whole B2B SaaS & GTM beat go out daily or weekly. A claim several independent sources made ranks higher — that counts agreement, not accuracy.
The blogs and newsletters are one part of the beat. Every B2B SaaS & GTM source, all media — or just the podcasts.
