Dylan Matthews is a policy journalist, effective altruism advocate, and former senior correspondent at Vox, where he founded and led the Future Perfect newsletter and section for seven years. Known for his deep-dive reporting on global health, animal welfare, and evidence-based philanthropy, Matthews embodies his own editorial philosophy: he donated a kidney to a stranger in 2016, initiating a chain that helped four people. As of December 2025, he joined Coefficient Giving (backed by Open Philanthropy) to manage the $120M+ Abundance and Growth Fund, moving from writing about doing good to actually doing it.
Kelsey Piper is an American journalist and effective altruism advocate best known for her work at Vox's Future Perfect newsletter, where she spent seven years covering AI safety, global catastrophic risks, evidence-based philanthropy, and education policy. She broke major stories including OpenAI's non-disparagement agreements and conducted the first post-collapse interview with Sam Bankman-Fried. In August 2025, she left Vox to co-found The Argument, a Substack newsletter focused on reasoned policy debate. A Stanford Symbolic Systems graduate who pledged 30% of her lifetime income to charity, Piper brings a rare combination of technical fluency, ethical rigor, and accessibility to some of the most consequential questions of our time.
Matthew Yglesias is one of America's most influential political writers - a Harvard-trained philosopher turned media entrepreneur who co-founded Vox and then bet on himself by launching Slow Boring, a Substack newsletter that earns him over $1.4 million a year. Known for his contrarian, rigorously argued takes on housing, immigration, economics, and American governance, he occupies a strange and productive niche: too wonky for Twitter, too heterodox for legacy media, and too prolific for anyone to ignore.
