Perplexity AI, Inc., an American privately held software company known for its AI-powered search engine, completed a Series D funding round in 2025, raising $500 million and valuing the company at $14 billion. The round, part of a broader trend of substantial investments in artificial intelligence startups, underscored Perplexity's rapid growth and ambition to challenge established search engines. By September 2025, the company's valuation had climbed further to $20 billion, reflecting continued investor confidence and market expansion.
The company was founded on August 22, 2022, by Aravind Srinivas, Denis Yarats, Johnny Ho, and Andy Konwinski, engineers with backgrounds in back-end systems, machine learning, and artificial intelligence. Its flagship product, a search engine that synthesizes answers from live web content with cited sources, launched on December 7, 2022, and quickly gained traction. By February 2023, Perplexity reported two million unique visitors, and by April 2024 it had raised $165 million, crossing a $1 billion valuation.
Funding History and Growth
Perplexity's funding trajectory accelerated significantly in 2024 and 2025. In January 2024, the company raised $73.6 million in a Series B round at a valuation of approximately $520 million, led by investors including Nvidia and Jeff Bezos. By April 2024, an additional $200 million round pushed the valuation to over $3 billion. In June 2024, a Series C round of $500 million brought the valuation to $9 billion, with participation from Databricks and other existing backers.
The Series D round in 2025, again raising $500 million, valued Perplexity at $14 billion. This round included investments from Microsoft and other strategic partners, reflecting growing interest in AI-native search. The company's valuation continued to rise, reaching $20 billion by September 2025, according to company statements. Investors have included prominent figures such as Nat Friedman, Tobias Lütke, and venture firm 1789 Capital, known for its association with Donald Trump Jr.
Products and Services
Perplexity's core offering is an AI-driven search engine available as a free web portal, with a premium tier called Perplexity Pro that provides access to advanced models such as GPT-5.4, Claude 4.6, and Gemini 3.1 Pro, as well as proprietary models like Sonar (based on Llama 3.3) and R1 1776 (based on DeepSeek R1). The company has expanded into various verticals, including a Shopping Hub launched in November 2024 with backing from Amazon and Nvidia, finance features introduced in October 2024, and an assistant launched in January 2025.
In July 2025, Perplexity released Comet, an AI browser based on Chromium, initially for top-tier subscribers and later free to download in October 2025. The company also launched Perplexity Computer in February 2026, a general-purpose AI agent for autonomous multi-step tasks, and Personal Computer in April 2026, a local-device extension. Additionally, Perplexity has been contracted to build a chatbot for Truth Social, Donald Trump's social media platform.
Series D Details and Strategic Moves
The Series D round in 2025 was part of Perplexity's aggressive expansion strategy. In January 2025, just before the U.S. ban on TikTok, Perplexity submitted a proposal to merge with TikTok US, though the deal did not materialize. In August 2025, Perplexity bid $34.5 billion to purchase Chrome from Google, proposing it as a remedy to antitrust litigation. These moves signaled Perplexity's ambition to compete directly with Google in the search market.
In December 2025, footballer Cristiano Ronaldo took an undisclosed stake in Perplexity and entered a global brand partnership. By early 2026, Perplexity's valuation reached $21.21 billion following a Series E-6 round. In January 2026, the company signed a three-year, $750 million agreement with Microsoft to use its Azure cloud and Foundry service, giving access to models from OpenAI, Anthropic, and xAI. Amazon Web Services remained its primary cloud provider.
Leadership and Vision
CEO and co-founder Aravind Srinivas has been a vocal advocate for AI's potential to transform work. In a March 2026 All-In podcast episode, he described incoming AI-related layoffs as a 'glorious future' that frees people from unfulfilling jobs and enables entrepreneurship. His leadership has guided Perplexity through rapid growth and strategic pivots, including a shift to a subscription-first model in February 2026, discontinuing AI-integrated advertising to preserve user trust.
Controversies and Legal Challenges
Perplexity has faced legal scrutiny over copyright and trademark issues. In June 2024, Forbes publicly criticized the company for using its content without authorization. Major media organizations, including the BBC, Dow Jones, and The New York Times, have alleged unauthorized scraping and content use. Analyses by Wired and Cloudflare found that Perplexity used undisclosed web crawlers with spoofed user-agent strings to access websites that block scraping, raising ethical and legal questions about its data practices.
Market Position and Outlook
As of 2025, Perplexity stood as a significant contender in the AI search space, competing with OpenAI's ChatGPT and Google's Search with AI Overviews. Its valuation growth from $1 billion in April 2024 to $20 billion in September 2025 reflected strong investor interest in AI-native search. The company's partnerships with major cloud providers and model developers positioned it to scale, though legal and ethical controversies posed ongoing risks. In February 2026, Perplexity's pivot away from advertising to a subscription model marked a strategic bet on user trust over ad revenue, a move that could redefine its revenue streams in a competitive landscape.
