Charities
Each card below shows so called 'meta-organisations' related to effective giving, effective altruism, and promoting high-impact philanthropy. These organisations do work such as outreach, capacity building, fundraising, charity incubation, and evaluation.
26 organisations
High Impact Professionals
A career-support organisation helping experienced professionals move into high-impact work, increase effective giving and use their networks for positive impact.
11.7X most likely multiplier
High Impact Professionals reports that their impact multiplier of 11.7x is conservative estimate and shares it along with another multiplier of 16x. It is a self-evaluated, cross-domain figure combining career transitions and giving pledges.
No uncertainty range published.
More figures and context
- 2025 outputs. More than 50 high-impact career transitions and around 70 new effective-giving pledges, producing approximately $2.5 million in estimated counterfactual impact.
- Methodology. The estimate combines career transitions and giving pledges, adjusts for individual and programme counterfactuality, caps the value of outcomes at 2.5 years, and uses Giving What We Can-style assumptions for giving pledges.
Cause areas supported
HIP's impact is not publicly detailed in exact percentages per cause area, but they report that their focus includes Global Health, AI Safety, Animal Welfare and Climate Change.
Giving Green (When donating to 'Support Our Work')
Research team evaluating and recommending high-impact climate nonprofits, and running a regranting fund.
11X most likely multiplier
Giving Green reports that each operational dollar has historically generated $11 in additional donations to high-impact climate charities.
No uncertainty range published.
Cause areas supported
- Effective Climate Work — 100%
share of recorded donations, 2025–2025
Effective Altruism Australia (When donating to their operations)
Independent Australian fundraising foundation directing tax-deductible donations to evaluated effective charities across multiple causes.
9X most likely multiplier
Scenario range
Plausible range: 7× (conservative scenario) – 9× (best guess)
· Last updated 2026-10-09
Cause areas supported
While Effective Altruism Australia has not publicly shared the exact cause areas, it is safe to assume that it aligns with the broader effective altruism movement's focus on high-impact global causes.
Giv Effektivt (When donating to their operations)
Danish donation platform that passes 100% of donations to GiveWell- and Giving What We Can-recommended charities.
7.1X most likely multiplier
Giv Effektivt projects that each krone spent on operations will generate about 7 kroner of impact-equivalent funding from 2025 onward. Its estimated adjusted historical multiplier for 2022–2024 was around 17x; the projected figure is lower and should be treated as forward-looking. Their unadjusted figure (gross multiplier) was: 20x (in 2022–2024).
No uncertainty range published.
More figures and context
- Historical adjusted multiplier, 2022–2024: about 17x. A retrospective result, in contrast to the 7x forecast.
- Adjustment model. The model estimated a 66.6% counterfactual/effectiveness adjustment, with an interval of 57.7% to 74.4%.
Cause areas supported
- Global Health & Wellbeing — 100%
share of recorded donations, 2025–2025
Giving What We Can (When donating to their operations)
Runs the 10% Pledge and a donation platform that routes money to independently evaluated, highly effective charities worldwide.
7.1X most likely multiplier
GWWC estimates that each dollar supporting its work generated around $7 in counterfactual value for highly effective charities in 2025, with a 1.5x conservative scenario. This is an average estimate for the year, not necessarily a marginal funding estimate.
Scenario range
Plausible range: 1.5× (conservative scenario) – 7.1× (best guess)
· Last updated 2026-10-09
More figures and context
- Rounding. GWWC's published 2025 executive summary reports the result rounded to 7x.
- Earlier evaluations (prior periods only). 6x for 2023–2024; 30x best guess and 9x conservative for 2020–2022. These are shown for context and are not blended into the current estimate.

Animal Charity Evaluators (When donating to their operations)
Evaluates and recommends highly effective animal-advocacy charities, and makes grants of its own.
6X most likely multiplier
ACE estimates a counterfactual giving multiplier of about 6x, explained in its counterfactual report.
No uncertainty range published.
More figures and context
- Historical gross multipliers. 11x in 2020 and 7.3x in 2018. These are historical gross influenced-giving figures, not current counterfactual multipliers.
- Newer reporting. ACE influenced at least $59 million between January 2019 and March 2025, of which about $28 million would not otherwise have been donated, plus $3.8 million in counterfactual movement-grant funding. They are not used for the main multiplier.
Cause areas supported
- Animal Welfare — 100%

Mieux Donner (When donating to their operations)
French effective-giving organisation that directs donations to evaluated high-impact charities.
5.3X most likely multiplier
Mieux Donner reported a 5.3x multiplier for 2025. This is treated as a counterfactual figure.
No uncertainty range published.

Ge Effektivt (When donating to their operations)
Swedish donation platform for evaluated effective charities, independent nonprofit since 2021.
4.7X most likely multiplier
Ge Effektivt's counterfactual giving multiplier was 4.7x in 2025, its most recent figure. Earlier years: 4.5x (2024), 2.1x (2023), 2.9x (2022) and 3.7x (2021).

80,000 Hours
Research-backed career advice and job board helping people direct their working lives toward high-impact careers.
NaN most likely multiplier
No public multiplier found.
No current giving multiplier is shown. 80,000 Hours' work combines career changes, community growth and donations, which a single giving multiplier cannot capture.
More figures and context
- Historical research note (not a current multiplier). Its 2016 evaluation included estimates such as a 0.5x realised donation multiplier, 4.5x including anticipated donations, and about 9x using financial rather than opportunity costs. Its 2017 review gave broader impact-value estimates, including 18.5x on financial costs and 6.1x including opportunity costs.
- Caveat. These figures are old and scenario-dependent, and they combine career changes, community growth and donations. They are not current giving multipliers.

Effektiv Spenden (When donating to their operations)
German donation platform (operated by UES gGmbH, Berlin) directing donations to evaluated effective charities across global health, climate, and animal welfare.
NaN most likely multiplier
Their unadjusted figure (gross multiplier) was: 26x (in 2025).
Historical figures: Published, counterfactual methodology available
More figures and context
- Earlier estimate, 2019–2021. Best guess 17.9x; conservative 10.4x. The 2020–2022 estimate is used as the main number because it is the most recent available overlapping period.
- Historical uncertainty. Calculations have had wide uncertainty; a prior public report cited a broad 11x–91x counterfactual range for 2021.

Founders Pledge
Pledge platform for tech entrepreneurs and founders to commit equity or proceeds to effective charities, backed by in-house research.
NaN most likely multiplier
Their unadjusted figure (gross multiplier) was: 16.9x to high-impact opportunities; 31.1x to the charitable sector overall (in 2025).
Historical figures: Published, gross/attributed leverage only
More figures and context
- Total charitable-sector leverage, 2025: 31.1x. For each $1 donated to Founders Pledge, it reported helping to move $31.10 to the charitable sector overall. This includes charitable giving beyond its high-impact funding opportunities, so the two figures should not be compared as like-for-like.

GiveWell (When donating to 'Unrestricted')
Charity evaluator that performs deep-dive research and recommends top global-health and development charities.
NaN most likely multiplier
No public multiplier found.
GiveWell is kept as an evaluator, but no X-factor is shown. Money moved divided by operating costs is not a counterfactual multiplier, and GiveWell has itself cautioned that money moved is not a complete estimate of impact versus a world where GiveWell did not exist. No X-factor until a credible counterfactual methodology and a compatible operating-cost denominator are available.

Rethink Priorities
A research organisation that aims to improve decisions by grantmakers and organisations across global health, animal welfare, global catastrophic risks and other high-impact areas.
NaN most likely multiplier
No public multiplier found.
Rethink Priorities has discussed models in which research can generate multiples of direct-giving impact, but no robust public retrospective X-factor for Rethink Priorities itself was found.
More figures and context
- Not a validated multiplier. Model-based statements about research leverage are conceptual, not a validated organisation-level multiplier, so no figure is shown.
