Perplexity

Perplexity AI, founded in August 2022 by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski, is a San Francisco-based company specializing in AI-powered search and assistant technologies. The company integrates large language models with real-time web search capabilities to provide users with direct, detailed answers to their queries, accompanied by source citations. Its flagship product, Perplexity, offers conversational search experiences, while Comet, launched in October 2024, is an AI-powered web browser designed to compete with established browsers like Google Chrome and Microsoft Edge. Comet enables users to perform tasks such as booking meetings, sending emails, and making purchases through conversational interactions, all backed by AI-generated responses. In February 2026, Perplexity introduced 'Computer,' a cloud-based AI agent integrated directly into macOS, leveraging 20 frontier models and advanced search to autonomously understand user goals and complete tasks. This product aims to enhance productivity by automating complex workflows and providing real-time information retrieval. As of April 2026, Perplexity reported an annualized revenue of $500 million, marking a 335% year-over-year increase. The company's valuation reached $20 billion in September 2025, following a $200 million funding round. Notable investors include SoftBank and Nvidia. Perplexity has established partnerships with media organizations such as Le Monde and Prisa Media, integrating their content into its AI-driven platforms. However, the company has faced legal challenges, including lawsuits from The New York Times and other media outlets alleging copyright infringement related to AI content generation. Despite these challenges, Perplexity continues to expand its product offerings and user base, positioning itself as a significant player in the AI search and assistant market.
