PDF Shareholder letter: Reddit cites Profound's analysis showing it is the most cited domain across AI models, ahead of Wikipedia, YouTube, Forbes, and others

For LLMs and AI search engines, these conversations and the knowledge they create are essential for training. Platforms like Reddit, where people discuss every aspect of life—from the trivial to the transformative—are the backbone of building AI that actually works. That’s why Reddit is the #1 most cited domain for AI across all models, per data collected by Profound. In an automated world that depends on human knowledge, we view Reddit as one of the most important and differentiated data sources.

We believe this validates what we’ve always thought: human conversation is not being replaced by AI; instead, it’s becoming more important. AI doesn’t invent knowledge—it learns from us. From real people, sharing real perspectives. You can’t have artificial intelligence without actual intelligence.
