Email notification and monitoring tools

Entries dated before the index start are sparse, with one entry in each month from 2011 to 2025, showing a low but persistent rate of new product ideas. Traction leaders are hermes-invoice-radar with 4 stars, while comingsoonest and Newton Mail - Email App have 0 stars each.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
