12 SaaS started advertising
These went from barely advertising to real spend. The libraries show who is live, not who began, so this needs a series rather than a snapshot.
Counted 25 October 2026, today.
Every day so far
Read from the public ad libraries of Meta, Google and LinkedIn. We read about 1,400 companies a day, so 96% of the catalogue has been read again inside the last month, and every number here carries the date we counted it. Each day keeps the page it was published on and is never rewritten.
