Perplexity AI, a trailblazer in the realm of artificial intelligence, was founded on January 1, 2022. The company emerged from the creative minds of former OpenAI employees, including Aravind Srinivas, who now serves as its CEO. Based in California, Perplexity AI has quickly made a name for itself by developing an advanced conversational response engine and search platform that leverages large language models to deliver precise answers without requiring user registration.
What sets Perplexity apart is its unique architecture known as Retrieval-Augmented Generation (RAG). This allows it to provide not just answers but also source citations—something traditional search engines often overlook. Users can engage with the platform freely and explore various features like unlimited follow-up questions and image generation capabilities.
In less than two years since its inception, Perplexity AI has achieved remarkable milestones. By mid-2023, it boasted over ten million monthly active users and nearly thirteen million website visits by February 2025—a testament to its growing popularity.
Financially speaking, the company has attracted significant investment through multiple funding rounds. Notably, it secured $500 million during its Series C round at a valuation of $9 billion and later raised another $200 million in September 2025—pushing its valuation up to an impressive $20 billion. High-profile investors such as Jeff Dean and Yann LeCun have shown interest in this innovative venture.
However, it's not all smooth sailing; media scrutiny led to copyright lawsuits from outlets like Forbes and Wired starting June 2024. Additionally, challenges arose when they launched their mobile Comet browser amidst legal disputes with Amazon regarding purchasing functionalities on behalf of users.
Despite these hurdles—and even service interruptions due to AWS outages—the future looks bright for Perplexity AI as they continue expanding their offerings into new domains like smartphone integration through partnerships with companies such as Motorola.
