Perplexity AI, Inc., an American privately held software company, operates a web search engine that processes user queries and synthesizes responses using large language models. Founded in August 2022 by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski, the company has grown rapidly, attracting substantial investment and partnerships. In 2024, Perplexity AI completed a funding round that valued the company at over $1 billion, a key step in its trajectory toward becoming a major player in the generative AI space.
Funding History and Valuation
Perplexity AI's financial growth has been marked by several significant funding rounds. In February 2023, the company reported two million unique visitors to its search engine, indicating early traction. By April 2024, Perplexity had raised $165 million in total funding, which valued the company at over $1 billion. This 2024 round was a critical milestone, elevating Perplexity to unicorn status and attracting a diverse group of investors, including Jeff Bezos, Tobias Lütke, Nat Friedman, Nvidia, and Databricks. Additionally, 1789 Capital, a venture capital firm associated with Donald Trump Jr., provided funding. The company's valuation continued to climb, reaching $14 billion by June 2025 after a $500 million round, and $20 billion by September 2025. As of early 2026, Perplexity AI reached a valuation of $21.21 billion following its Series E-6 funding round.
Products and Services
Perplexity's primary offering is a search engine that uses large language models to generate responses to user queries by searching and summarizing web-based content. The service is available for free without registration, following a freemium model. The paid tier, Perplexity Pro, offers enhanced security, data protection, and access to advanced backend models such as GPT-5.4, Claude 4.6, and Gemini 3.1 Pro. The company has also developed its own models, including Sonar (based on Llama 3.3) and R1 1776 (based on DeepSeek R1).
Internal Knowledge Search allows Pro and Enterprise Pro users to search web content and internal documents simultaneously, supporting file uploads in formats like Excel, Word, and PDF. Enterprise Pro users can index up to 500 files. The Search API provides developers with programmatic access to Perplexity's search infrastructure.
In November 2024, Perplexity launched a Shopping Hub, an online shopping platform that generates product recommendations and enables direct purchases, backed by Amazon and Nvidia. In October 2024, the company introduced finance-focused features, including stock price tracking, earnings data, and basic financial analysis tools, sourcing data from Financial Modelling Prep.
In January 2025, Perplexity launched the Perplexity Assistant, an AI tool designed to improve search functionality by performing tasks such as using rideshare apps or identifying songs, and maintaining context across actions. The assistant can use a phone's camera to answer questions about surroundings or on-screen content, though it remains in development and may require workarounds for certain features.
In July 2025, Perplexity launched Comet, an AI browser based on Chromium, initially limited to top-tier subscribers but released for free in October 2025. The browser integrates the Perplexity search engine. Perplexity has also been contracted to produce a chatbot for Truth Social, Donald Trump's social media platform.
In February 2026, Perplexity launched Perplexity Computer, a general-purpose AI agent designed to autonomously perform multi-step tasks using multiple large language models and specialized subagents. In April 2026, the company introduced Personal Computer, an extension of Computer that operates on a user's local device.
Leadership
Aravind Srinivas serves as CEO and co-founder of Perplexity AI. He previously held research positions at OpenAI, Google DeepMind, and other AI research institutions, focusing on machine learning and artificial intelligence. In a March 2026 All-In podcast episode, Srinivas commented on AI-related layoffs, describing them as a 'glorious future' that frees people from jobs they dislike and creates opportunities for entrepreneurship.
Controversies
Perplexity AI has faced legal scrutiny over allegations of copyright infringement, unauthorized content use, and trademark issues from major media organizations, including the BBC, Dow Jones, and The New York Times. According to analyses by Wired and Cloudflare, Perplexity uses undisclosed web crawlers with spoofed user-agent strings to scrape content from websites that prohibit or block web scraping. In June 2024, Forbes publicly criticized Perplexity for publishing a story largely copied from a proprietary Forbes article without proper attribution.
Strategic Moves
In July 2024, Perplexity announced a publishers' program to share advertising revenue with partners. On January 18, 2025, the day before the impending U.S. ban on TikTok, Perplexity submitted a proposal for a merger with TikTok US. On August 12, 2025, Perplexity made a bid to purchase Chrome from Google for $34.5 billion, stating that the sale could remedy antitrust litigation against Google. In December 2025, Cristiano Ronaldo took an undisclosed stake in Perplexity AI and entered a global brand partnership. In January 2026, the company entered a three-year, $750 million commitment with Microsoft Azure to secure GPU capacity. In February 2026, Perplexity transitioned to a subscription-first model, discontinuing its AI-integrated advertising strategy to preserve user trust in its 'answer engine.'
Impact and Future
Perplexity AI's rapid growth and high valuation reflect the increasing demand for AI-powered search and information synthesis. The company's partnerships with major investors and its expansion into browsers, assistants, and enterprise tools position it as a significant competitor in the artificial intelligence landscape. As of early 2026, Perplexity continues to innovate, with plans for further product development and market expansion.
