Where the money goes when nobody completes

Every rule about where the money goes has an edge case that shows what the company actually believes. Ours is the challenge nobody completes.

It is rare. It is also the one situation where the fund sits there with nobody to return it to, no completer to reward, and no external party watching. Whatever rule you write for that case, you write it knowing nobody will be looking.

The rule we started with

The original rule was simple and it was bad: nobody completes, Pledro keeps the fund.

You can defend it on the mechanics. Completing is the only route back to your entry — that is the whole design, and it is stated on screen before anybody commits. If nobody completed, nobody earned their entry back, and there is no completer whose reward the money could become.

The problem is not the logic. The problem is what it makes us on the day it happens.

It gives Pledro a single outcome in which the worst possible result for every person in a challenge is the best possible result for us. However rarely that occurred, it would sit in the business model as a quiet incentive pointing the wrong way, and we would know it was there.

What the rule is now

Changed in August 2026, and built the same week.

Pledro keeps a tenth of the fund. The other 90% will be donated to a partner charity.

The tenth is the same ceiling that applies everywhere else on the platform — our share is never more than 10% of everything entered, in any circumstance, and this case is not an exception to that. The remaining 90% leaves the business.

Two details are worth saying out loud, because they are the kind of thing that gets rounded in the wrong direction otherwise.

The rounding falls on us. Where a tenth does not divide into whole pennies, our share is rounded down, so the charity is never a penny short. On a £99 fund that is £9.90 to Pledro and £89.10 recorded.

Entrants still get nothing back. This did not change and it should not: completing is the only route back to your entry, and a rule that returned entries when nobody finished would empty the word "commitment" of its meaning. The 90% does not come out of the completers' share, because there are no completers. It comes out of what would otherwise have been ours.

Two honest caveats

No money has gone anywhere. Real-money entries are not live. The whole beta runs on free Grind Coins, which are not money, so nothing has been recorded for any charity and nothing has been paid to one.

No charity has been chosen. One will be, and it will be named on this site before the first paid entry is ever taken. Until then, the setting that holds the charity's name is deliberately empty — and the code refuses to complete a challenge in this state rather than proceeding without one. A missing charity must never quietly become "Pledro keeps it", so we made that impossible rather than promising it would not happen.

Recording is not paying. We would rather say that plainly than let a reader assume we are already writing cheques.

Why 90% and not a token

Because a token amount is a marketing line and this is not meant to be one.

The purpose of the rule is to remove an incentive, and a 5% gesture would leave the incentive almost entirely intact. Ninety per cent removes it: on the day nobody completes, Pledro earns the same tenth it would have earned on a normal challenge, and nothing more. The outcome stops being unusually good for us. It becomes ordinary, which is the whole point.

The line this buys

Pledro never takes more than 10% of total entry fees, in any circumstance.

That sentence holds across every case the reward engine can produce — a few people missing, most people missing, everybody missing, nobody entering enough to run at all. It is not a claim we make in copy and check by hand. It is written as an assertion in the tests that govern how a challenge completes, so a change that broke it would fail the build before it could ever reach anybody.

There is a fuller version of the arithmetic, with a calculator you can move the numbers around in, on Pledro for Good.
