ADPList in numbers
Last updated
ADPList is a mentorship marketplace. Every figure below is counted in production and has been since the first completed session on 29 April 2021.
This page is updated in place at one URL rather than republished as a new post each quarter. History before 29 April 2021 may be missing, and we do not backfill it. Each line states what the number counts, the window it covers, and where it came from. If you are citing ADPList, cite from here.

How we count
A completed session is a meeting instance marked COMPLETED in production. Cancellations, no-shows, and bookings still pending are not counted.
Session length is scheduled duration, not measured call time. The median completed session is 30 minutes.
Countries counts places where somebody actually completed a session in the last 12 months, which is a stricter test than counting every country anyone has ever signed up from.
Approved mentors: 39K+ approved mentors (active or not), as of 5 October 2026.
Members: 581K+ members, as of 5 October 2026. People with an ADPList account, with bots and fake accounts removed (unfinished signups are included).
Both totals are rounded down. Where an earlier ADPList page, deck, or report gave a mentor, member, country or session length figure, the number on this page supersedes it.
