Community Notes is a crowdsourced fact-checking system on X (formerly Twitter) that allows regular users to add contextual notes to potentially misleading posts. Using a proprietary 'bridging-based agreement' algorithm that rewards notes approved by people who typically disagree, the system has grown to nearly 1 million volunteer contributors and delivered 30 billion note views in 2024—more than double the prior year. The product's success demonstrates that open, decentralized approaches to information quality can outperform traditional centralized fact-checking.

Success came from combining exceptional talent density, unwavering focus on consumer needs, and deep regulatory knowledge.

Pioneer is a founder-scouting platform that identifies promising people working on interesting ideas around the world using psychometrics and machine learning, then creates and funds companies for them on the spot.

The company is partially funded by Daniel and investors including Stripe co-founders and Marc Andreessen.
