Donation-funded basic income via small recurring contributions, since 2014.
Over 330,000 people have funded 1,439 basic incomes through micro contributions. Around 1.1 to 1.2 million people are registered as draw participants. Contribution pattern: recurring monthly micro donations (association self-report; the exact distribution is not publicly broken down).
Our takeaway: Micro contribution plus association form scales to six-digit donor numbers when the story stays consistently tellable over time.
