Today, Open Philanthropy is becoming Coefficient Giving. [Our mission](https://coefficientgiving.org/our-approach/) remains the same, but our new name marks our next chapter as we double down on our longstanding goal of helping more funders increase their impact. We believe philanthropy can be a far more vital force for progress than it is today; too often, great opportunities to help others go unfunded. As Coefficient Giving, our aim is to make it as easy as possible for donors to find and fund them. (For more on how we chose our new name, what’s changing, and what’s staying the same in this next chapter, see [here](https://coefficientgiving.org/research/the-story-behind-our-new-name/).)

The world has seen [enormous improvement](https://ourworldindata.org/a-history-of-global-living-conditions) in living conditions over the last two centuries, but continues to face devastating problems philanthropy is well-placed to address. [Nearly half of children](https://pubmed.ncbi.nlm.nih.gov/33713615/) in poor countries have elevated blood lead levels even though there are proven methods to [dramatically reduce lead exposure](https://coefficientgiving.org/funds/lead-exposure-action-fund/the-plan/). [Billions of animals](https://ourworldindata.org/how-many-animals-are-factory-farmed) live in horrendous conditions on factory farms, though [corporate campaigns](https://www.dwarkesh.com/p/lewis-bollard) can meaningfully reduce their suffering. [Strict zoning](https://worksinprogress.co/issue/the-housing-theory-of-everything/) and [other barriers](https://www.theatlantic.com/science/archive/2019/07/we-need-new-science-progress/594946/) slow growth and progress, but YIMBY and the broader abundance movement are [beginning to turn the tide](https://www.theargumentmag.com/p/have-you-heard-the-good-news-on-housing). Advances in synthetic biology will increase the risk of [novel bioweapons](https://www.foreignaffairs.com/world/new-bioweapons-covid-biology), but [ambitious biosecurity efforts](https://defensesindepth.bio/the-four-pillars-a-hypothesis-for-countering-catastrophic-biological-risk/) to improve detection and response are there for the taking. And while advances in AI hold enormous promise, they could also pose unprecedented risks, leaving a [narrow window](https://coefficientgiving.org/research/our-approach-to-ai-safety-and-security/) to implement technical and policy safeguards.

Over the last decade, we’ve developed a model for finding and funding the most cost-effective opportunities to solve these problems. We’re proud of
