Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
Experiment
Crowdfunding for research projects
Experiment funds science: a researcher posts a hypothesis, a budget and a method, and backers pay for the work rather than for a product. Every project is reviewed by a person before it goes public, and funding is all or nothing, so a project that misses its number charges nobody. What backers get back is the result, usually a paper or a data set. Anybody looking for a reward tier will find this a strange place.
Our note
Set the goal at what the work actually needs rather than at an ambitious number, because all-or-nothing turns an over-ambitious target into no money at all. The 8 percent is at the high end for crowdfunding, and what buys it is a reviewed, credible platform that scientific backers already trust.
Kindest
Donation pages that start without a subscription
Kindest gives a nonprofit donation forms, recurring giving and donor records on a free plan that takes a percentage instead of a monthly fee, and waives even that on the first fifty thousand dollars of a first year. The paid tier lowers the percentage and adds text campaigns and scheduled time with a person. Forms default to asking the donor to cover fees. Everything here assumes a registered charity rather than an individual.
