Startups that closed their waitlist and opened sign-up

In Q4 2026 (to 9 November 2026), 3 startups closed their waitlist and opened sign-up, out of 1,797 with at least two captures in the archive that quarter. These are observations in the archive, not a market-wide rate. Coverage differs by quarter.

What counts

The homepage had a waitlist at the previous check and now offers sign-up instead. A change counts in a quarter only when both checks it lies between fall in that quarter; the share is out of the startups with at least two visible captures in that quarter. Two captures do not guarantee a usable comparison, and observation frequency varies. Method.

334 observations cannot be allocated to a quarter. Inspect their date ranges. Zero counted changes does not establish that nothing changed.

334 observations · less precisely dated. Showing 201–240.

Dated less precisely

These changes happened between two checks in different quarters, or were already showing at the first check, so they are not counted in any quarter above.
