Quora

Quora (operating at quora.com) is a social question-and-answer platform engineered for knowledge sharing and discovery. Founded in 2009 by Adam D'Angelo and Charlie Cheever and headquartered in Mountain View, California, Quora transforms how individuals seek and contribute expertise. Unlike traditional forums or search engines, it aggregates insights from a global community, fostering structured, high-quality discussions on nearly any topic. Under the hood, the platform leverages user-generated content moderated by algorithms and community guidelines, ensuring relevance and credibility. This allows curious individuals, professionals, and researchers to access nuanced perspectives while contributing their own expertise. With reported annual revenue of approximately US$20 million, Quora operates independently, prioritizing long-term knowledge growth over traditional monetization models.
