Technology, Information and Internet Mountain View, CA 201–500 employees Founded 2009 Privately Held

Quora operates a dual-platform knowledge network: a public Q&A site with hundreds of millions monthly visitors, plus Poe, an AI chat aggregator for creators. The tech stack reveals heavy investment in real-time personalization (Kafka, Spark, Trino, RAG) and multi-model AI integration (Gemini, Claude). Active migration from Redshift to Trino, combined with recommendation-system projects across feed, notifications, and ads, signals architectural modernization toward lower-latency ranking and real-time ad delivery.
