Perplexity is an AI search engine that answers your questions directly with sourced, written responses instead of a list of links.
Perplexity is a search engine, but not the kind that hands you ten blue links and wishes you luck. You ask it a question in plain language, and it writes you a direct answer, streaming it out word by word, with numbered footnotes linking to the websites it pulled the facts from. That last part matters: the answer comes with receipts, so you can check the source yourself. People use it for quick research, comparing products, digging through academic papers, or just getting a straight answer without clicking through ads and clutter.
The company makes money in a few ways. Most people use it free, but a paid tier called Perplexity Pro gives subscribers access to stronger AI models and more searches, and that subscription is the business's main engine. It also sells a version to businesses, and it runs a shopping feature where retailers pay to have their products appear with a "buy" button when someone asks about, say, a good pair of running shoes. The pitch to users is simple: one tool that searches the live web and thinks at the same time, rather than an AI chatbot stuck with old training data or a search engine that makes you do the reading. Perplexity was founded in 2022 by Aravind Srinivas, a former researcher at OpenAI and Google's DeepMind, along with Denis Yarats, Johnny Ho, and Andy Konwinski. It grew fast by riding the AI wave, and it has raised money from big-name investors at eye-popping valuations for such a young company. It also struck a notable deal to put its answer engine inside some devices and platforms, and it launched a browser of its own, betting that the way people find information is being rebuilt from scratch. The business sits in a brutal neighborhood. It competes with Google, whose search engine still owns the habit of billions of people, and with AI assistants like Microsoft's Copilot and OpenAI's ChatGPT. Its edge is focus and speed: it is a small, nimble team built entirely around answering questions well, unburdened by a giant advertising machine to protect. The catch is that running powerful AI models is expensive, and the company must persuade enough people to pay for something they can partly get free elsewhere.
In 2022, Aravind Srinivas left OpenAI and teamed up with Denis Yarats, Johnny Ho and Andy Konwinski to start Perplexity. The problem was that search engines handed you a list of links and left you to do the reading. Perplexity's answer was to give you a direct, summarized answer, with the sources cited so you could check it. And it did this without building its own giant AI model, instead combining other companies' models with a live look at the web, a setup known as RAG.
People liked the idea fast. By early 2023 the site was pulling in millions of visits a month, and the iOS app passed a hundred thousand downloads within days of launching that spring. Soon the company had raised over $28 million, and it was talking with shopping and payments companies like Instacart and Klarna about putting conversational search inside their apps.
Then came the money. Perplexity raised four rounds in 2024, and its valuation shot from around half a billion dollars in January to $9 billion by November. The final round, led by IVP, was half a billion dollars, with backers like Nvidia, Databricks and Jeff Bezos joining in. It had become one of the most valuable AI startups in the world, and its ambitions grew with it.
That ambition turned toward Google directly. In mid-2025 Perplexity launched Comet, its own AI browser aimed at Chrome and Google's search dominance. Days later it raised another $100 million at an $18 billion valuation, and then it made a stunning $34.5 billion bid for Google Chrome itself, a clear signal it wanted to be a real alternative to Google.
Selling was not the plan. CEO Aravind Srinivas said the company intended to stay independent rather than be bought by the likes of Meta, Google or Apple. He framed the mission as offering a genuine alternative to Google's search, browser assistant and Gemini, and that commitment shaped how the company chose to compete.
In February 2026 Perplexity launched Perplexity Computer, a cloud-based AI agent that does complex computer tasks with little hand-holding. Days later came Personal Computer, which runs more than twenty AI models to act as a round-the-clock assistant. The company was no longer just a better search engine; it was helping people finish work, and it was now up against Microsoft Copilot and Anthropic's agents.
The pivot paid off fast. Annualized revenue raced from under $250 million at the start of 2026 to over $750 million by August, mostly on the back of Perplexity Computer. Nvidia was reportedly in talks to invest at a valuation above $30 billion, well up from the prior round, showing how much the agent business had changed the company's trajectory.
In less than a year Perplexity made three product leaps: search to browser, browser to agent, agent to Computer. Revenue climbed from around $100 million to the $500 million level while headcount rose only 34%. Through it all, the company stayed a multi-model orchestrator, pulling together many AI models rather than trying to build one dominant model of its own.
There is also a genuine fight over the rules of the game. Perplexity has been accused by news publishers of scraping their content and summarizing it without permission, and it has responded by launching a revenue-sharing program that pays publishers when their work is used. How that battle shakes out — and whether AI answer engines like Perplexity become the new front door to the web or a niche tool — is the big question hanging over the whole company.
