Who keeps this running
Noosphere is paid for by subscriptions, donations and identified sponsors. Here they are, by name and with a link. None of them decides anything about what is in the corpus or about what the answers say.
Updated 26 August 2026
There are none yet. If your organisation works in research, training or harm reduction, you could be the first — and the founder rate stays frozen for two years.
What this page guarantees
That all of them are on it. Any organisation paying to appear anywhere in Noosphere appears here, with the tier it has booked. There are no quiet sponsorships and no arrangements that go unmentioned.
- They do not influence the corpus. Not which documents go in, not which come out, not how they are weighted.
- There is no sponsored answer. A sponsor appears in an answer only if a document in the corpus mentions it on its own account.
- There are no sponsored nodes in the concept graph.
- They hold no right of veto over any document.
The full rules are in the editorial and sponsorship policy, and what each sponsor signs contains a specific clause setting them out.
And who is not
We do not accept anyone selling controlled substances in any country, retreats offering them on Spanish territory, unproven claims of cure, anyone demanding that content be changed, anyone asking to install tracking pixels, or anything aimed at people under 18.
