Welcome, Mike O'Meara Show listener!
GiveWell searches for the charities that save or improve lives the most per dollar. We recommend a small number of charities that can do an incredible amount of good.
Your donation can make a meaningful difference for some of the poorest people in the world.
Which donations are eligible for the match?All first-time donations from new donors are eligible to be matched up to $100. GiveWell will allocate each matching donation in proportion to the original donation. For example, if you choose to split your donation equally between three of GiveWell’s recommended charities, we will also split your matching donation equally between those three charities.
How do I make sure my donation is matched?
You can either click the “Make a matched donation” button on this page or select "Mike O'Meara" on the donation page. Donations made through any payment method will be matched. If you’re unsure if your donation was matched, you can email us to confirm at firstname.lastname@example.org.
The gold standard for giving.
How we maximize your gift's impact:
Our Research Process
We extensively research each charity before recommending it. We continue evaluations each year after.
We look at independent studies of charity programs, such as randomized controlled trials, to understand their effectiveness.
We build in-depth models to analyze charities' cost-effectiveness. We refine this throughout our charity evaluation process, based on their budget and monitoring, to estimate impact per dollar spent.
Interviews and site visits
We conduct extensive interviews with charity staff. We visit charities in the field to see their work on the ground.
We review charities' past spending and forecast their future spending, to better understand their track record and expected impact.
We ask charities to share their data showing how well their programs reach the intended beneficiaries so we can better understand how successful charities' programs have been.
We continually assess the work, progress, and future plans of our recommended charities. We will remove a charity recommendation if we no longer believe the organization meets our criteria.

Check our work.
It's right to ask questions of any charity that promises incredible impact. It's hard to do incredible things.
We publish the full details of our analysis so you can fully vet our reasoning. We also share mistakes we've made which are relevant to evaluating our work.
Why our top charities work in lower-income countries.
Helping people in high-income countries is expensive, and the gains can be more marginal. People living in low-income countries face many problems that have ready solutions, such as children dying from malaria or suffering from parasitic worms.
Donating internationally is the most cost-effective way to provide lifesaving help.
