ADPList in numbers
Last updated
ADPList is a free mentorship marketplace. The platform figures below — mentors, sessions, minutes, and countries — are counted in production and have been since the first completed session on 29 April 2021. The search and signup figures come from Google Search Console and Amplitude over the shorter windows named on each row.
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. Totals that include every booking regardless of status are much larger and we do not publish them as completed sessions.
Minutes are the scheduled duration of completed sessions added together, not measured call time. The median session is 30 minutes.
An active mentor is an account currently bookable, not everyone who has ever registered as a mentor, so this number can go down as well as up.
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.
Where an earlier ADPList page, deck, or report gave a larger figure for mentors, sessions, minutes, or countries, the number on this page supersedes it.

Is ADPList free?
Effectively yes. ~99% of sessions cost the mentee nothing: 0.8% of bookings created in the last 12 months were paid, and 0.3% of lifetime completed sessions were paid. There is no subscription and no paywall on browsing or booking — a small number of mentors offer an optional paid session type, and everything else is free. Mentors are volunteers rather than being paid per session. Source: production DynamoDB.
How many countries does ADPList reach?
People in 165 countries completed an ADPList session in the 12 months to 21 August 2026. That is countries with real completed session activity in the window, not the number of countries anyone has ever registered from. Source: production DynamoDB.
