The Proof-Backed Giving Loop makes reporting part of the contribution itself. At Charity: Water's first event, attendees put money into a clear box under a stated promise that it would support clean water. Harrison says the organisation then used the proceeds for a well and repairs in Uganda and returned to the same supporters with photographs, video of flowing water, and satellite locations. The mechanism links a defined group of contributors to a documented project, reducing the ambiguity that originally made many of Harrison's friends distrust charities. A responsible version must preserve consent and avoid claiming more attribution than the evidence supports. The loop is complete only when contributors receive a clear account of what was funded, where it happened, and what observable result followed.
Origin
Harrison used the approach after Charity: Water's first birthday fundraiser, sending attendees photographs, video, and project locations from Uganda.
Core principles
- 01A contribution becomes more credible when supporters can see what followed.
- 02Evidence should connect the specific campaign to a specific result.
- 03Visual and location evidence can make remote impact concrete.
- 04Closing the loop is part of the experience, not an optional report.
How to run it
- 1
State the use
Tell contributors what the campaign is intended to fund before collecting money. Keep the promise specific enough to report against later.
Pro tip Separate the promised use from broader mission language.
Watch out Do not imply a precision the delivery model cannot support.
- 2
Preserve the link
Record the campaign, amount, contributor group, and intended project. Maintain enough provenance to connect later evidence to the original appeal.
Pro tip Use a stable campaign identifier across finance and project records.
- 3
Document the result
Capture appropriate evidence when the funded work is delivered, such as photographs, short video, project records, or location data. Obtain consent and protect vulnerable people.
Pro tip Show the completed work rather than relying only on celebratory language.
Watch out Transparency does not override dignity, privacy, or security.
- 4
Return the proof
Send contributors a concise explanation of what happened, supported by the evidence. Make the connection to their campaign clear without assigning unsupported individual causality.
Pro tip Use the same channel through which the group originally engaged when possible.
- 5
Keep it verifiable
Retain the underlying project and financial records so the public-facing proof is not the only evidence. Correct material changes or shortfalls openly.
Pro tip Design the archive and reporting process before campaign volume grows.
Watch out A polished story without traceable records can reproduce the distrust the loop is meant to solve.
In the wild
Harrison says 700 attendees contributed about $15,000 at Charity: Water's first event. The organisation funded a well and repairs in a Ugandan refugee camp, then emailed attendees photographs, video of clean water flowing, and satellite images showing the project locations.
→ Supporters received visible evidence connecting the event's promise to completed water work.
A youth centre raises money for ten laptops, records the restricted appeal, obtains consent before photographing the installed equipment, and sends donors the invoice, delivery confirmation, and a short account of how sessions changed.
→ The centre closes the loop without exposing the children it serves or exaggerating long-term outcomes.
Common mistakes
Stopping after the donation
The trust mechanism depends on returning evidence to supporters after the funded work occurs.
Using generic impact imagery
Unlinked images do not establish that a particular campaign supported the project being shown.
Trading dignity for transparency
The transcript supports visual proof, but it does not justify publishing identifiable people or sensitive locations without appropriate consent and safeguards.
Is it for you?
Best for
Organisations delivering concrete, documentable projects whose supporters rarely see the work directly.
Not ideal for
Sensitive services where public images, locations, or stories could compromise dignity, consent, privacy, or safety.
