The Story Behind Perplexity AI: From Startup to Search Disruptor

Perplexity AI was founded in 2022 by Aravind Srinivas (ex-OpenAI), Andy Konwinski, Denis Yarats, and Johnny Ho — visionaries frustrated with the inefficiencies of keyword-based searches and hallucination-prone AI chats4.

Their goal: Build an engine that combines the vastness of the web with the intelligence of large language models (LLMs) to provide verifiable answers.

By 2023, it gained traction with its Retrieval-Augmented Generation (RAG) technology, which fetches live data from sources like news sites, academic papers, and forums, then synthesizes it using models like GPT-4 or Claude.

Fast-forward to 2025: Perplexity has pivoted to compete directly with Google, emphasizing accuracy, speed, and transparency. Recent milestones include a $200 million funding round that boosted its valuation to $20 billion and partnerships like the Notion integration for seamless in-app querying2520.
