Perplexity AI, Inc. is an American technology company headquartered in San Francisco, California, that specializes in artificial intelligence and machine learning. Founded in August 2022 by a team of prominent engineers—Aravind Srinivas (CEO), Denis Yarats (CTO), Johnny Ho (CSO), and Andy Konwinski (President)—the company has positioned itself at the forefront of the emerging conversational "answer engine" market. Moving beyond traditional search engines that return a list of links, Perplexity leverages advanced large language models (LLMs) to synthesize information from across the web, delivering direct, context-aware, and highly precise answers complete with transparent inline citations. The company's flagship product is its web-based conversational search platform, complemented by a Google Chrome extension and dedicated mobile apps for iOS and Android. To serve a diverse user base, Perplexity operates a freemium model. Its core search functionalities are available for free, while the premium subscription service, Perplexity Pro, grants users access to more advanced language models (such as GPT-5.5, Claude, and Gemini), increased file upload capacities, and an Internal Knowledge Search feature designed for deep research. For corporate environments, the company offers Perplexity Enterprise Pro, which delivers data security alongside robust user management and authentication controls. Perplexity has also expanded its ecosystem with Comet, an AI-powered assistant designed to streamline browser workflows, and specialized platforms like the Shopping Hub, which provides AI-driven product recommendations. Financially, Perplexity AI has experienced a meteoric rise, establishing itself as a prominent tech "unicorn." The company's innovative approach attracted significant early investments from high-profile technology figures and institutional investors, including Jeff Bezos, Nvidia, New Enterprise Associates (NEA), and IVP. While it initially grew through venture funding—raising its valuation to $1 billion by early 2024 and $9 billion by late 2024—its valuation soared to $20 billion by September 2025. Following a Series E-6 funding round in early 2026, its valuation reached $21.21 billion. To support its massive computational demands, Perplexity entered into a three-year, $750 million commitment with Microsoft Azure in January 2026 to secure GPU capacity. Strategically, the company has heavily prioritized user trust; in February 2026, leadership shifted Perplexity to a subscription-first model by entirely discontinuing its AI-integrated advertising strategy to ensure completely objective, un-sponsored search results. Additionally, to balance the intellectual property ecosystem, Perplexity runs a Publishers' Program that allows content creators and media partners to share in subscription revenues linked to AI-generated citations. Controlled by its original founders and backed by major industry giants, Perplexity AI continues to reshape how global users access, verify, and interact with digital information.
