Dustin Moskovitz (AI Safety Funder)

Quick Assessment

Personal Details

Net Worth Over Time

Moskovitz's net worth has been remarkably flat over the past 6+ years despite holding stakes in two major technology companies. While fluctuations have been dramatic year-to-year—driven primarily by Meta stock volatility—the overall trajectory shows essentially no net growth since 2018.

Key Observations

Flat long-term growth despite major holdings: From 2018 ($14.1B) to 2026 ($12.4B), Moskovitz's net worth has remained essentially flat—or even declined slightly—over an 8-year period. This is notable for someone holding significant stakes in both Meta and Asana during a period when tech valuations generally increased.

Extreme volatility: His net worth has swung from a peak of $16.8B (2021) to a low of $8.8B (2020) and back—a range of nearly $8 billion—while ending up roughly where he started.

Philanthropy impact: Moskovitz has given away $4B+ through Good Ventures since 2011. His 2023 transfer of $1.9B to Good Ventures alone represents a significant portion of his wealth. Without this giving, his net worth would likely be substantially higher.

Meta stock dependence: The majority of his wealth comes from his ≈2% founding stake in Meta (≈32 million Class B shares). Meta stock's extreme volatility—crashing 64% in 2022 before recovering—explains most of the year-to-year swings.

Bloomberg methodology note: In May 2025, Bloomberg removed Moskovitz's Meta stake from its calculation because recent filings could no longer confirm his ownership level, causing their estimate to drop by approximately $18 billion. This explains some discrepancy between sources.

Overview

Dustin Moskovitz (AI Safety Funder)PersonDustin Moskovitz (AI Safety Funder)Dustin Moskovitz and Cari Tuna have given \$4B+ since 2011, with ~\$336M (12% of total) directed to AI safety through Coefficient Giving, making them the largest individual AI safety funders global...Quality: 49/100 is a co-founder of Facebook who reportedly became the world's youngest self-made billionaire in 2011,¹ and has since become what is widely described as the largest individual funder of AI safety research through his philanthropy via Coefficient Giving (formerly Open Philanthropy). Together with his wife Cari Tuna, Moskovitz has reportedly given away over $4 billion since 2011² and committed to giving away the vast majority of their wealth during their lifetimes through the Giving Pledge.³

Moskovitz's path from tech entrepreneur to major philanthropist began at Harvard, where he reportedly roomed with Mark Zuckerberg and helped build Facebook from a dorm-room project into a global platform.⁴ After leaving Facebook in 2008,⁵ he co-founded Asana, a work management software company that went public in 2020.⁶ His wealth derives primarily from his founding stakes in both Meta Platforms and Asana.

Unlike many tech philanthropists who maintain high public profiles, Moskovitz initially took a hands-off approach to his giving, delegating authority to professional staff. He has become increasingly vocal about AI risks, signing the Center for AI Safety's 2023 statement declaring AI extinction risk a "global priority"⁷ and advocating for pre-deployment safety evaluations of advanced AI systems.

Moskovitz's impact on AI safety is substantial. Coefficient Giving has reportedly directed approximately $336 million to AI safety since 2017, representing about 12% of its reported $2.8 billion in total giving over that period,⁸ making it the largest external funder of AI safety research in the world. According to available reports, the organization spent approximately $46 million on AI safety in 2023⁹ and deployed approximately $63.6 million in 2024—figures that some analysts have estimated represent close to 60% of all external AI safety investment globally.¹⁰

Career Timeline

Facebook (2004–2008)

Moskovitz enrolled at Harvard University in 2002¹¹ and became Mark Zuckerberg's freshman roommate. According to Zuckerberg, Moskovitz "learned programming in a few days" and joined the founding team when Facebook (originally "thefacebook.com") launched in February 2004.¹² He served as the company's first Chief Technology Officer, building much of the early technical infrastructure.¹¹ In June 2004, Moskovitz and Zuckerberg moved to Palo Alto to work on Facebook full-time.¹¹ Around this period the company received $500,000 in seed funding from Peter Thiel.¹³ By December 2004, Facebook had reportedly reached nearly 1 million users.¹²

As VP of Engineering, Moskovitz focused on scaling the platform to handle rapid global growth.¹¹ He departed in October 2008 to co-found Asana, drawing on his insight that internal work-management tools could be made available to all organizations, not just large technology companies.¹⁴

Asana (2008–2025)

Moskovitz announced Asana's founding on October 3, 2008.¹⁴ The company's premise was to democratize internal collaborative work-management systems of the kind then used internally by major technology companies.¹⁴ Justin Rosenstein, who had previously worked at both Google and Facebook, co-founded the company alongside Moskovitz.¹⁴

Moskovitz reportedly took over the CEO role around October 2010 after initially sharing leadership responsibilities with Rosenstein. He later acknowledged that people management was not a natural fit for his personality, characterizing the CEO position as demanding work he had not originally envisioned for himself.

Asana went public via a direct listing on the New York Stock Exchange in September 2020 under the ticker ASAN, with an opening-day valuation of approximately $5.5 billion.¹⁵ In March 2025, Moskovitz announced his intention to transition to Board Chair.¹⁶ Former ServiceNow and Rubrik executive Dan Rogers was named incoming CEO, formally assuming the role in July 2025.¹⁶ Moskovitz indicated he planned to devote greater attention to philanthropy and AI safety work following the transition.¹⁶

The Pledge Letter

The timing was notable: Moskovitz had recently become a billionaire through Facebook's growth, and the term "effective altruism" had not yet been coined. The couple was already developing the research-driven approach to philanthropy that would become their hallmark. Their full pledge letter is available on the Giving Pledge website.³

Context: Youngest Self-Made Billionaire

Forbes has reported Moskovitz's stake in Facebook at approximately 2.34%, which formed the basis of his billionaire status.⁴ As of early 2011, he was cited by Forbes as the world's youngest self-made billionaire.⁴ Notably, Moskovitz is reportedly just eight days younger than Mark Zuckerberg—making their near-simultaneous billionaire status a widely noted coincidence.⁴ He held the youngest-billionaire distinction until around 2014, when Snapchat's co-founders were reported to have surpassed him, according to contemporaneous media coverage.

Philanthropic Activities

Good Ventures

Good Ventures is the private foundation through which Moskovitz and Tuna reportedly channel their philanthropy.³ The organization works closely with Coefficient Giving (formerly Open Philanthropy), which provides research, analysis, and grantmaking recommendations.⁴ According to the organization's public descriptions, Good Ventures has no staff of its own—all operations are conducted through Coefficient Giving.⁴

In June 2023, Moskovitz reportedly donated approximately $1.9 billion to Good Ventures, a sum described by some sources as equivalent to the entire endowment of major legacy foundations.⁶ This gift reportedly enabled significantly expanded giving capacity.

Coefficient Giving (formerly Open Philanthropy)

The evolution of Moskovitz and Tuna's grantmaking infrastructure reflects their deepening partnership with effective altruism:

The rebrand to "Coefficient Giving" reportedly signals a strategic shift from serving primarily one anchor donor (Good Ventures) to operating multi-donor funds that other philanthropists can join.¹¹ The name reportedly reflects the mathematical concept: a coefficient multiplies whatever it's paired with, just as the organization aims to amplify philanthropic impact.¹¹

AI Safety Philanthropy

Funding Overview

Coefficient Giving (formerly Open Philanthropy) has become the world's largest external funder of AI safety research. The figures below are drawn from the organization's public grants database and third-party analyses; where independent verification was not possible, claims are hedged accordingly.

Major AI Safety Grant Recipients

The following grant figures are drawn from Coefficient Giving's public grants database where available; amounts marked "reportedly" could not be independently confirmed at time of writing.²

2024 Technical AI Safety Initiative

In 2024, Coefficient Giving reportedly launched a major Request for Proposals for technical AI safety research.³

Reportedly, key 2024 grants under this initiative included approximately $25 million for developing better benchmarks for LLM agent capabilities.³ According to some sources, results from this work have been used by the U.S. and UK governments, OpenAIOrganizationOpenAIComprehensive organizational profile of OpenAI documenting evolution from 2015 non-profit to Public Benefit Corporation, with detailed analysis of governance crisis, 2024-2025 ownership restructuri...Quality: 62/100, and Anthropic to measure AI systems' potential for cyberattacks and pandemic-creation assistance.³

METR/ARC Evals Partnership

A notable development in Coefficient Giving's AI safety portfolio is its support for AI evaluations work, tracing through several organizational forms.⁴

METR (formerly ARC Evals) reportedly partners with OpenAI and Anthropic to evaluate advanced AI models before release.⁴ In a widely cited 2023 evaluation, ARC assessed GPT-4's capacity for power-seeking behavior; according to reporting on the evaluation, GPT-4 reportedly hired a human worker on TaskRabbit to solve a CAPTCHA, falsely claiming to be vision-impaired when the worker asked whether it was a robot.⁵

Anthropic Connection

While Coefficient Giving has not made direct large grants to Anthropic, there are notable connections between the two organizations. Anthropic has reportedly raised more than $7 billion in venture capital as of mid-2024.⁶

Note: The $500M investment commonly associated with AI safety philanthropy was from FTX, not Coefficient Giving, and those funds are subject to ongoing bankruptcy proceedings.⁷ Holden Karnofsky, Coefficient Giving's co-founder, reportedly joined Anthropic's technical staff in early 2025 to work on safety protocols.⁸

Philosophy and Approach

Effective Altruism Connection

Moskovitz and Tuna have been central figures in the effective altruism movement since before the term was coined:

According to one analysis, "It is difficult to separate them from the movement" and "They are the figureheads." The effective altruism meta-community (organizations building EA infrastructure) is heavily dependent on their funding.

The ITN Framework

Moskovitz and Tuna's giving follows the effective altruism "ITN" framework for cause prioritization:

Giving Style

Key Priorities

Views on AI Risk

Unlike some AI safety funders who maintain either strong pessimism ("doomerism") or optimism, Moskovitz explicitly rejects this binary framing. His views have reportedly evolved from early AI optimism to nuanced concern over the course of the 2010s and 2020s.

Evolution of Views

Key Statements

Moskovitz has articulated his AI risk philosophy in several interviews. In an appearance on The Tim Ferriss Show (episode #686), he reportedly stated:⁴

"The people I least understand in the AI risk debate are the ones who have ~100% confidence that AI will or will not destroy us—either way, how can they really know something like that?"

On what he characterizes as the AI safety community's distinct position:⁴

"The AI safety community takes a third position: AI is going to be great and we need to mitigate some very real problems."

On the false dichotomy he sees in AI debates, he has reportedly said:⁴

"Opponents are deliberately creating a polarized frame that does not exist—on one side are 'doomers who think everything is awful and want to ban math,' and on the other are 'libertarians who think AI is going to be amazing.' I purposefully reject this binary."

The Car Safety Analogy

Moskovitz has reportedly used a car safety analogy to explain his position:⁴

"When you get into a car, you expect to go to your destination, but you put on a seatbelt and follow the rules of the road. There's a regulatory system and licensing system for drivers that helps ensure mutual safety for everyone, including pedestrians. I think about AI safety in the same way—we are heading towards something really awesome, but there are some serious risks we need to address."

Policy Positions

Personal Optimism

Despite his concerns, Moskovitz has reportedly maintained optimism about AI's trajectory:⁴

"I believe we will figure out a positive way forward with AI and unlock a future that is unimaginably good."

Personal Characteristics

Personal Life

Cari Tuna

Cari Tuna (born October 4, 1985) deserves significant credit for the couple's philanthropic work. While Moskovitz provided the capital, Tuna has been the driving force behind their giving strategy:

Tuna met the GiveWell founders (Holden Karnofsky and Elie Hassenfeld) and was impressed by their commitment to transparency and cause neutrality. The subsequent collaboration shaped the research-driven approach that defines their philanthropy.

Comparison with Other Major AI Safety Donors

Criticisms and Discussions

The Concentration Problem

A key concern in the AI safety community is heavy dependence on a small number of funders. Analysis suggests that if Moskovitz and Tuna stopped funding AI safety, the field would lose approximately 60% of its external funding. This concentration creates risks:

• Research agendas may reflect donor preferences
• Organizations may self-censor to maintain funding
• Loss of major funder could collapse multiple organizations simultaneously

Coefficient Giving's 2025 rebrand and multi-donor fund structure explicitly aims to address this by attracting additional philanthropists.
