Quora’s mission is to grow the world’s collective intelligence. We do this by connecting people and AI to share knowledge, collaborate, and solve problems together. By reducing friction in how intelligence is shared—publicly on Quora and privately on Poe—we’re building platforms that make knowledge more accessible and accelerate learning and progress for everyone. Quora is a global knowledge sharing platform with hundreds of millions of monthly unique visitors, connecting writers who have knowledge across millions of topics with a global audience of readers who want to learn from their collective experience. Poe aggregates access to the best models from many different AI companies in a single chat interface across all platforms, and enables creators to build and monetize applications that use these models.

Brainly is an AI-powered learning platform used by hundreds of millions of students, parents, and educators around the world. Built with educators, Brainly helps students understand their schoolwork, not just finish it. It combines the moments that matter most in school — homework help, studying, and test prep — into a single product, guiding students through their own assignments step by step and turning everyday work into targeted practice for what's next. Brainly began as a crowdsourced, peer-to-peer question-and-answer community, and that community of verified Experts is still part of the foundation. What's changed is everything built on top of it: AI help, test prep, study tools, and progress visibility for parents, layered with expert review so students get the speed of AI with the accuracy of a human educator.
