Big picture

Period	Development summary	More details
2006–2008	Initial years	GiveWell starts conducting its grant application process. Initial struggles in founding are experienced, with very little money moved through the website. Some controversies emerge in the leadership.
2009–2010	Stabilization	GiveWell achieves growth in money moved. GiveWell staff begin making site visits to the areas served by current and potential top charities.
2011–2012	Partnership	Good Ventures is formed and starts injecting money. Annual cycles are standardized.
2013–2014	Relocation	GiveWell moves to the San Francisco Bay Area, where people have become strong supporters of effective altruism. GiveWell Labs grows in this period.
2015 onward	Reorganization	A spectacular growth in money moved through recommendations is experienced in this period. GiveWell Labs separates from GiveWell, renaming as Open Philanthropy Project.

Highlights by year

Year	Event
2007	GiveWell launches. In the first year, fifty-nine organizations apply for GiveWell grants, with fifteen being considered to produce adequate information about their activities. Population Services International (PSI) is announced as first recommended charity, and becomes the recipient of GiveWell's first substantial donation.
2008	GiveWell moves US$35,021 through its website, and receives 130 donations.
2009	GiveWell decides to rate only charities that meet a minimal standard of transparency. The evaluator moves US$143,013 through its website (A 308% increase from the previous year). The number of donations reaches 665 (a 412% increase from 2008).
2010	GiveWell manages to track over US$1.5 million in donations to top charities, compared to just over $1 million in 2009. Its website traffic nearly doubles compared to the previous year, and donations through the website nearly triples. The evaluator moves US$399,456 through its website (a 179% increase from 2009), whereas the number of donations reaches 976 (a 47% growth from the previous year).
2011	A strong growth is experienced during the year. GiveWell tracks over US$5 million to top charities, compared to about US$1.5 million in 2010. Its website reaches US$1,305,089 in movement (a 227% increase from 2010), whereas its number of donations more than triples to 3,099 (a 218% growth from the previous year). In 2011 GiveWell broadens its search on charitable organizations to include flag promising charities, based on additional characteristics. The set of heuristics for flagging charities worth investigating further is partially developed by incorporating research and previous heuristics from the 2009 report.
2012	GiveWell starts searching for organizations working on immunization, nutrition and other global health programs. The evaluator identifies three top priorities for the year: to make significant progress on GiveWell Labs; find more top charities under the same basic framework as our existing recommendations; and expand its team.
2013	GiveWell develops a cause selection framework, getting basic context for assessing causes within policy-oriented philanthropy and scientific research funding.
2014	GiveWell tracks 27.8 million dollars moved to its recommended charities, about 60% more than in 2013. The total number of donors giving to GiveWell's recommended charities or to GiveWell unrestricted would not grow significantly (up 9% to about 9,300). Many new donors who gave less than $1,000 in 2013 would not give again in 2014, but among those who gave $10,000 or more in 2013, a higher proportion would give again in 2014.
2015	GiveWell tracks approximately 100 million dollars in donations going to its recommended charities as a result of its research.
2015–2016	GiveWell seeks to expand top charity room for more funding and consider alternatives to its top charities by inviting other groups that work on deworming, net distributions, and micronutrient fortification to apply. This would lead to adding Sightsavers' deworming program, the END Fund's deworming program, Project Healthy Children, and Food Fortification Initiative to GiveWell's lists.
2017	The Open Philanthropy Project becomes an independent entity.
2018	GiveWell tracks US$141 million in money moved in donations to its recommended charities or through its Incubation Grants program. In the same year, the GiveWell moves US$65 million to its top charities.
2019	GiveWell processes US$54.1 million in donations.

Interactions

The dates of first mention may be inaccurate insofar as earlier mentions were missed. Dates are in YYYY-MM-DD format.

Counterpart entity	Founding year of counterpart entity	Entity type	First mention by GiveWell	First mention of GiveWell by that entity (if applicable)	Notes
Population Services International (PSI)	1970	Charity	2007-01-07		Population Services International (PSI) is one of GiveWell's top recommendations from early 2007 till the end of 2009, when GiveWell would come up with an updated list based on its research.
Charity Navigator (CN)	2001	Charity evaluator	2007-01-09		GiveWell's first mention of Charity Navigator, and many of its subsequent mentions, are in the context of criticism of too much focus on the "overhead ratio" of charities, a metric that CN focuses on. GiveWell also mentions CN in its business plan as another organization providing a somewhat similar service but one that is different in important ways. GiveWell also responds to personal blog posts by Trent Stamp, the President of Charity Navigator at the time.
Bill & Melinda Gates Foundation (BMGF; Gates Foundation) (timeline)	2000	Foundation	2007-01-20	2019-07-01	GiveWell often mentions the Gates Foundation, generally positively, though at times being critical or puzzled about the Gates Foundation's lack of transparency and unwillingness to make recommendations or accept money from individual donors. GiveWell recommends that Good Ventures co-fund a grant with the Gates Foundation in 2012.
Network for Good	2001	Donation processor	2007-01-20		On the GiveWell blog, Karnofsky brings up criticisms of Network for Good's donation-processing fees and argues that PayPal may be better. Katya of Network for Good responds with clarifications, and Karnofsky updates his views somewhat. In 2017, GiveWell says that the blog post no longer represents their views on Network for Good.
Tactical Philanthropy (main blogger: Sean Stannard-Stockton)	2006	Blog/website	2007-02-17	2007-02-16	Sean Stannard-Stockton writes positively about GiveWell on the Tactical Philanthropy blog; GiveWell links to the post the next day from their roundup. The two blogs link to each other occasionally over the coming years with mutual respect and admiration, even though some of the commentary would be critical.
Copenhagen Consensus	2004	Prioritization project / cause research	2007-11-27		In 2008 and 2009, while in the early stages of exploring different cause areas within global health and development, GiveWell often cites the Copenhagen Consensus as one of the information sources it consults. GiveWell's references to the Copenhagen Consensus become less frequent starting 2010.
Disease Control Priorities Project (DCPP)	1993 (2006 for DCP2)	Prioritization project / cause research	2007-11-27		GiveWell frequently cites the work of the Disease Control Priorities Project, specifically the Disease Control Priorities Report (DCP2), in its exploration of various cause areas between 2008 and 2011. In 2011, GiveWell discovers an error in the deworming cost-effectiveness estimates in DCP2.
Abdul Latif Jameel Poverty Action Lab (J-PAL) (timeline)	2003	Program evaluator	2008-02-05		GiveWell cites and references the work of J-PAL, more in its early years (2008 to 2011) though occasionally even after that.
Innovations for Poverty Action (IPA) (timeline)	2003	Program evaluator	2008-02-05		GiveWell cites and references the work of IPA, more in its early years (2008 to 2011) though occasionally even after that.
Coalition for Evidence-Based Policy	2001 (?)		2008-02-05		GiveWell cites and references the work of the Coalition for Evidence-Based Policy, mostly in its early years (2008 to 2010). GiveWell even has a guest post from the Assistant Director at the Coalition for Evidence-Based Policy.
Global Burden of Disease Study (GBD)	1990	Prioritization project / cause research	2008-08-11		GiveWell cites GBD's 2000 report several times in blog posts in August and September 2008, and occasionally in the coming years.
Against Malaria Foundation (AMF) (timeline)	2004	Charity	2008-09-26		GiveWell discovers AMF and starts investigating it, adding AMF to its list of recommended charities in July 2009, and cementing its top charity status in December 2009. With the exception of a year-long period where GiveWell marks AMF as not having room for more funding, GiveWell continues to recommend AMF as a top charity.
Center for Global Development (CGD) (timeline)	2001	Research think tank	2009-01-07		GiveWell cites the work of researchers at CGD in several blog posts over the years starting 2009, including the work of David Roodman. GiveWell spin-off organization Open Philanthropy later hires David Roodman as an advisor. GiveWell also recommends grants to CGD in the 2010s, and GiveWell spin-off Open Philanthropy makes several further grants to CGD.
Carter Center	1982	Charity	2009-02-09		Elie Hassenfeld of GiveWell starts investigating the Carter Center after finding some of its program activities promising. The investigation ends in 2009 with disappointment, as the Carter Center does not provide GiveWell with a useful budget breakdown between its programs.
Aid Watch	2009	Blog/website	2009-02-12	2012-07-18	In 2009, GiveWell cites and responds to several Aid Watch posts, including Aid Watch's posts arguing for cash transfers and cash as a benchmark.
Center for High Impact Philanthropy	2006		2009-03-04		GiveWell talks about the Center for High Impact Philanthropy (based at the University of Pennsylvania) in March 2009. The Center for High Impact Philanthropy is mentioned in further blog posts and comments on the GiveWell blog between 2009 and 2011.
Peter Singer	1946	Effective giving advocate	2009-03	2009-03-06	Peter Singer highlights GiveWell as a resource for donors interested in effective giving in his book The Life You Can Save. The GiveWell blog has a review of the book shortly after its publication. The GiveWell blog continues to reference and engage with Singer in the coming years, particularly in the context of obligations to give and cost-per-life-saved estimates.
Stop TB Partnership	2001	Charity	2009-04-03		GiveWell prepares a report on Stop TB Partnership, and then adds it to its top charity list. Stop TB Partnership is dropped from the top charity list around 2012.
Good Intentions are not Enough	?	Blog/website	2009-05-21		GiveWell frequently cites and mentions the work of the Good Intentions are not Enough blog, that tends to highlight cases where aid and charities don't work as well as expected.

Full timeline

Year	Month and date	Event type	Details
1999	November 30	Prelude (website registration)	givewell.org is registered (by a different organization).
2003	July 4	Prelude (website registration)	givewell.com is registered (by a different organization).
2003		Prelude	Holden Karnofsky graduates from Harvard with a degree in Social Studies. Karnofsky would spend the next several years in the hedge fund industry.
2004		Prelude	Elie Hassenfeld graduates from Columbia University with a degree in Religion. As well as Karnofsky, Hassenfeld would spend the next several years in the hedge fund industry.
2006	August	Prelude	Holden Karnofsky and Elie Hassenfeld, working at a hedge fund in Connecticut, set up an informal “charity club” with colleagues, to help them make informed decisions about their giving. Each person would pick a cause and then research the best charities working on that cause, evaluating them based on data and performance metrics. Hassenfeld and Karnofsky find this work so satisfying that it would ultimately lead them to create GiveWell.
2006	November 19	Online community	givewell.net is registered.
2006	November 25	Content creation	Probably the earliest GiveWell wiki edit is made on this date. The wiki would later be shut down.
2006	December 23	Content creation	The first post on the GiveWell blog is from this date. The initial tone of the blog would be playful and exploratory, with Holden Karnofsky and Elie Hassenfeld sharing the intermediate results of their investigations and using emotionally expressive language. Over time, the blog would mirror the organization's own growth in stature and influence and switch to a more formal, measured tone.
2006	December 28	Cause identification (malaria)	In a post on the GiveWell blog, Karnofsky expresses excitement about the seemingly low cost-per-life-saved ($200) of malaria net distribution based on numbers provided by Nothing But Nets for malaria net distribution, as well as a study of the effect of malaria net distribution on malaria-induced mortality. Karnofsky does not yet have enough details to make a concrete recommendation, but seems excited about the possibility, and argues that readers too should be excited at the possibility of saving lives at such a "bargain" price. GiveWell's interest in malaria nets would eventually lead to it recommending Against Malaria Foundation in 2010, an organization that GiveWell would recommend for the next decade, with brief pauses in due to lack of room for more funding.
2007	January 2		Holden Karnofsky blogs about his 2006 donation decisions, that are split between New Visions for Public Schools ($5000), Interplast ($2000), Children's Aid Society ($1000) and four other smaller causes ($256 each). Karnofsky argues for donating to fewer of the causes that one thinks are best rather than splitting donatons across a wide variety of causes that one does not think are all equally good; this repeats parts of an argument made previously by Steven Landsburg, though Karnosky still ends up splitting between seven charities. Karnofsky says that his decision was "based on about .01% of the information I wish I had". The only named charity in the list that would make it to the 2007 end-of-year recommendations would be Interplast, and none of these charities would make it to the GiveWell end-of-year recommendations starting 2009.
2007	January 7	Recommendation	In a blog post, Elie Hassenfeld announces GiveWell's first official recommendation: Population Services International (PSI) for their work on oral rehydration therapy (ORT) that helps combat diarrhea, for an estimate of $50 per life saved. PSI would also be a recommendation at the end of 2007, but would drop out of the recommendations in GiveWell's updated list at the end of 2009 and never return as a top charity.
2007	January, with some followup posts in March	Concept development (overhead ratio fallacy)	In a series of blog posts, Holden Karnofsky critiques the "overhead ratio" (the split of a charity's revenue that it spends on overhead versus direct program expenses) -- a prominent measure used by Charity Navigator to rate charities. Karnofsky says that the measure is useful to identify really wasteful charities, but that it does little to help figure out the effectiveness of a charity's programs and does not help identify the best charities.
2007	February	Update	A blog post by Elie Hassenfeld talks about the reactions of nonprofits working in the clean water space to the questions he posed to them about their work. He classifies the reactions into three categories: hostile, dumbfounded, and grateful. Hassenfeld feels that Population Services International is one of the few organizations that was able to provide an adequate response, but he'd like to do a lot better by the end of 2007.
2007	February 16	External citation	Writing for Tactical Philanthropy, Sean Stannard-Stockton praises the efforts of the GiveWell blog and project, calling it the "pissed off donor model" and saying: "I don’t agree with everything they write. But it is refreshing to see donors blogging instead of consultants and advisors (like me) telling everyone what donors want." He asks (rhetorically?) why foundations don't share more of their research publicly the way GiveWell has been.
2007	February 27	Concept development (cause neutrality, transparency)	Holden Karnofsky responds to Blog Carnival's prompt on what donors wish nonprofits knew about them. His first point: "I see you as competing with other charities." includes an early formulation of the idea of cause neutrality: REDIRECT Template:Blockquote Karnofksy's remaining points underline that he, as a donor, actually wants to know how his money will be used, and is looking to have impact and learn the truth rather than looking for "reassurance" or "customer service".
2007	April 7	Publication	GiveWell publishes The Case for the Clear Fund, its so called original business plan, written mostly to solicit the support and feedback of its existing contacts. Holden Karnofsky announces that he's quitting his hedge fund job on April 27 to devote himself full time to the Clear Fund / GiveWell, and Elie will also be taking a leave of absence from the hedge fund world to help Holden.
2007	April 28	Team	This is Holden Karnofsky's first day working full-time for GiveWell.
2007	June 9	Concept development (proven, cost-effective, scalable)	A blog post by Holden Karnofsky, talking about GiveWell starting to contact charities to apply for grants from it, says: "broadly, we want organizations with proven, effective, scalable ways of helping people." These adjectives would form a key part of GiveWell's self-description of the sort of charities and interventions it seeks to recommend.
2007	late June / early July	Official launch	GiveWell is founded by Holden Karnofsky and Elie Hassenfeld, with the purpose of evaluating, ranking, and recommending charities, focussing on evidence of effectiveness, cost-effectiveness, transparency, self-monitoring and need for funding. The organization has a board including Holden, co-founder Bob Elliott, and several others, and a set of focus areas.
2007	August 3		Elie Hassenfeld joins GiveWell full-time.
2007	November 11	Online community	GiveWell launches its website at www.givewell.net where it summarizes its research and findings to date. Until this time, GiveWell had been communicating its research through its blog and mailing list, but neither of these served the purpose of providing a concise description of what GiveWell currently recommends and why.
2007	November 20	Concept development (proven, cost-effective, scalable)	A blog post by Holden Karnofsky argues that in relative terms, there is a lot more money for innovative, high-risk projects and not enough money for scaling up existing projects that work. GiveWell is interested in focusing on the latter, and Karnofsky argues that more philanthropic money in general should go towards scaling up proven interventions.
2007	December 13	External citation	The Chronicle of Philanthropy covers GiveWell.
2007	December 17	Grantmaking	At a board meeting, the GiveWell staff and board try to figure out the best charities to fund in cause areas that GiveWell had been investigating. They aren't able to cover causes 3 and 4 as GiveWell hasn't done enough research in these yet. For "Employment assistance" the board unanimously chooses with HOPE after some discussion. For Cause 1, "Saving lives in Africa", the debate is between Population Services International (PSI) and Partners in Health (PIH), with heated debate ultimately leading to PSI being selected. For "Global poverty", the board goes with Opportunity International, despite overall reservations regarding the microfinance category. Audio of the board meeting does not survive, but a blog post goes into detail on the events of the meeting.
2007	December 19	Concept development (money goes farther in the developing world)	Elie Hassenfeld says that he regrets GiveWell having pledged $25,000 for one charity each in its five cause areas, as, based on the research they've done, they believe that the money donated to charities working to save lives in the developing world delivers much more value per unit money spent than money on the cause areas focused in the New York City area (such as the ones working on helping people find employment). This is an early clear articulation of the idea that donations go much farther when focused on global health and development and targeted at the developing world, an idea that would inform GiveWell's internal prioritization in future years as well as become part of their messaging to donors on their website.
2007	December 20	External citation	Stephanie Strom at The New York Times publishes article entitled "2 Young Hedge-Fund Veterans Stir Up the World of Philanthropy", featuring GiveWell and its founders.
2007	December 20	External citation	Rachel Emma Silverman and Sally Beatty at The Wall Street Journal publish article highlighting GiveWell among WSJ resources for donors.
2007	December 20	Interview	Holden Karnofsky and Elie Hassenfeld are interviewed by CNBC.
2007	December 24	Interview	Holden Karnofsky and Elie Hassenfeld are interviewed by NPR.
2007	December 27	Concept development (transparency, measurement, humility)	A blog post by Holden Karnofsky titled "Transparency, measurement, humility" identifies humility is an important underpinning value of the GiveWell value, and explains GiveWell's focus on transparency and measurement as both being due to its underlying focus on humility. Notable quote: REDIRECT Template:Blockquote In a later personal blog post in 2017 (after he was no longer working at GiveWell), Karnofsky would describe the evolution in his personal views, some of which is based on his experience of relatively high costs and low benefits of transparency.
2007	December	Controversy	Holden Karnofsky is discovered posting a question about GiveWell to community weblog MetaFilter using another individual's name, and then posting an answer about the organization with his own name but without disclosing his affiliation with GiveWell. Negative publicity would arise, leading Karnofsky to resign from the role of executive director, though he would later be reinstated. This would be one among several "astroturfing" incidents in which Holden Karnofsky and Elie Hassenfeld would participate over the time period; GiveWell would later post what they claim to be a full list of such incidents on their website as well as a FAQ on GiveWell and astroturfing.
2008	January 3	Content creation	The article GiveWell is created at Wikipedia. This is a stub and about half the article discusses the controversies around its co-founders' promotional methods.
2008	January 3, 6, 11	Controversy	The Clear Fund Board Meeting of January 3 is focused on discussion of the astroturfing / inappropriate marketing by GiveWell in December 2007, and leads to Karnofsky resigning from the executive director role and his position on the board. As followup, the board publishes two statements that are posted to the GiveWell blog on January 6 and January 11 respectively.
2008	March 4	Grantmaking	At a board meeting, the GiveWell staff and board decide what charities to grant to in the two remaining causes that weren't covered in the December 2007 board meeting. The charities are Nurse-Family Partnership for Cause 3 (early childhood care)and KIPP for Cause 4 (K-12 education).
2008	June 19	Publication	GiveWell's first-year review is published. The review evaluates GiveWell's performance on four goals: Research (B+), Website (B), Publicity (C, mainly due to the aggressive marketing tactics including Karnofsky's Metafilter promotion), and startup hurdles (B+).
2008	July 23		GiveWell announces the GiveWell Pledge, where donors make a formal, advance commitment to donate to charities based on what GiveWell finds after a year of research. The purpose is to demonstrate to GiveWell the level of interest donors have in its research.
2008	August 9	Strategy	At a board meeting, GiveWell board members agree that their top priority for the coming year is money moved, with research as a secondary priority.
2008	August 27	Concept development (proven, cost-effective, scalable)	A blog post by Holden Karnofsky articulates the idea that GiveWell is looking for proven, scalable, and cost-effective interventions. These adjectives would become part of GiveWell's description of its work, and as part of its rubric for evaluating its top charities.
2008	August 29	Concept development (the case against disaster relief)	A blog post by Holden Karnofsky approvingly summarizes the findings of the Disease Control Priorities report on the relatively lower cost-effectiveness of spending on disaster relief compared to spending on disaster-preparedness and on ongoing chronic issues. Several nuances are discussed. This would become part of GiveWell's standard advice on disaster relief.
2008	September 14 (with alternative dates from alternative sources)	Online community	GiveWell mailing list on Yahoo! Groups launches. A GiveWell blog post on October 21, 2008, however, dates the starting of the mailing list to July 2008 and its conversion to a public list to around the time of the public post (October 21).
2008	September 26	Top charities	GiveWell is referred to the Against Malaria Foundation (AMF) on this date. Holden Karnofsky blogs about how he's impressed by AMF's transparency as evidenced on its website. AMF would go on to become a GiveWell top charity in the coming years and GiveWell would direct tens of millions of dollars in funding toward it.
2008	November 17	Strategy	GiveWell publishes its Change of Direction, based on stuff discussed in the August 2008 board meeting as well as further updates since then. The main updates are in the direction of believing that it's more important to focus on research than on money moved for the near term.
2008	December 10	Interview	Holden Karnofsky is interviewed by NPR on the importance of researching for donations.
2008	December	Funding	The William and Flora Hewlett Foundation makes a $100,000 grant to GiveWell.
2008	?	Recommendation	After conducting an open grant application process and reviewing 59 applications in global health and development, GiveWell announces the first recommendations: Population Services International (PSI), which markets and distributes life-saving materials (mostly condoms and insecticide treated bednets); Partners in Health (PIH), which creates comprehensive health programs (hospital, health center, and community health workers) in disadvantaged, generally rural, areas in the developing world; and Interplast, which devotes to correcting deformities requiring surgery (such as cleft lip and palate deformities), both through direct treatment and through support of local doctors. These recommendations would be supplanted by GiveWell's 2009 end-of-year recommendations and none of these charities would return to GiveWell's top charities list after that.
2009	January	Team	GiveWell Board of Directors' member Ari Herman joins the organization.
2009	March	External citation	Australian philosopher Peter Singer publishes The Life You Can Save. Singer writes: REDIRECT Template:Blockquote A review of the book by William Easterly uses GiveWell's difficulties getting effectiveness information from charities to push back against Singer's claims of a clear moral obligation similar to that of saving a drowning child. In a review on the GiveWell blog, Holden Karnofsky agrees with Singer and also partly with Easterly's criticism, concluding: REDIRECT Template:Blockquote
2009	April 3	Top charities	GiveWell completes a preliminary report on the Stop TB Partnership, a charity that it is excited about. Stop TB Partnership would become a GiveWell top charity at the end of 2009 though it would leave the top charity list after a few years.
2009	July 1	Recommendation	GiveWell publishes its "2008-2009 international aid recommendations"; the top recommendations are Stop TB Partnership and VillageReach, and other recommended charities include Against Malaria Foundation, Population Services International, Partners in Health, and The Global Fund to fight AIDS, Tuberculosis and Malaria.
2009	July	Team	Natalie Crispin joins GiveWell as a Research Analyst.
2009	?	Team	GiveWell co-founder and Board Chairman Bob Elliott departs from the organization.
2009	?	Review	GiveWell conducts reviews of websites from over 300 charitable organizations, aiming to find ones that either implemented priority programs or published, on their websites, meaningful evaluations of their programs.
2009	?	Grantmaking	GiveWell conducts a grant application process for organizations running economic empowerment programs in the developing world. The $250,000 grant is offered to organizations providing economic empowerment programs in Sub-Saharan Africa.
2009	September 1	Grantmaking	GiveWell grants $42,523.55 to VillageReach and $42,523.55 to the Stop Tuberculosis Partnership. This money comes from donors who had donated to GiveWell to grant to its recommended charities at its own discretion. This would be the first officially announced "discretionary regranting" by GiveWell; discretionary regranting would later morph into the GiveWell Maximum Impact Fund.
2009	September 8	External citation	New York Times columnist Nicholas Kristof co-authors Half the Sky with his wife Sheryl WuDunn. The book points to GiveWell and Charity Navigator as donor resources.
2009	October 3	Concept development (cash as benchmark)	A blog post on the GiveWell blog discusses the idea of cash transfers as a benchmark, i.e., the idea that donations should pass the test of being more cost-effective than donating cash to beneficiaries. The post says: "In concept, we think it’s a great idea (and we proposed something similar for evaluations of U.S. charities). However, one major issue for individual donors is simply that we know of no charity that focuses on delivering cash directly to low-income people." This is a few years before the launch of future GiveWell top charity GiveDirectly that would be focused precisely on delivering cash directly to low-income people. The concept of cash as a benchmark would inform the thinking of GiveWell and its spinoff Open Philanthropy over the coming years, with the effectiveness of marginal donations to GiveWell top charities being reported in terms of their multiplier over cash.
2009	November 8	External citation	GiveWell is recommended by a Wall Street Journal article on resources for evaluating charities, along with Charity Navigator and GuideStar. Whereas Charity Navigator is described as covering 5,400 nonprofits and including "executive compensation, efficiency, organizational capacity, donor privacy policies, and administrative, fund-raising and program expenses", and GuideStar is described as having "nonprofit reports and tax forms for almost two million charities", GiveWell is described as having "in-depth information on individual charities and causes" and focusing on "how well programs work and their impact on the people they serve."
2009	Late months	Strategy	GiveWell begins to use "scenario analysis" asking how a charity's activities would change at different levels of total unrestricted funding.

Hassenfeld replies that the direction GiveWell has chosen is the right one, expressing his belief that it will mean a "more focused, intensely engaged board, and ultimately a more robust, more impactful GiveWell." After the resignations, GiveWell's Board of Directors retains five members: Timothy Ogden (Interim Chair), Cari Tuna, Holden Karnofsky, Julia Wise, and Elie Hassenfeld.

This decision sparks criticism from organizations like GiveDirectly, which argues that the funds could address immediate needs and help alleviate poverty.

The debate highlights broader issues of transparency and the balance between immediate action and strategic future investments in philanthropy.

This balanced approach aims to ensure both optimal impact and personal fulfillment in charitable giving.
