Perplexity AI

Perplexity AI has built the most credible challenger to Google Search in a decade — an AI-native search engine that provides cited, conversational answers to complex queries instead of a list of blue links to sift through. At a $9B valuation after its July 2024 funding round, the company has grown from zero to 15M monthly active users in 18 months through viral growth among researchers, engineers, and knowledge workers who value answer accuracy over advertising revenue. Unlike ChatGPT, Perplexity always cites its sources and provides real-time web access — features that make it uniquely useful for professional research. CEO Aravind Srinivas has positioned Perplexity as the 'answer engine' for the post-search-bar internet, and the product has received attention from Lex Fridman's podcast and major tech media.
