# Perplexity AI's Series B (2024)

Perplexity AI, an American AI search company, raised $73 million in a Series B round in 2024, valuing it at $520 million, amid rapid growth and legal challenges.

Perplexity AI, Inc., an American privately held software company, completed a Series B funding round in 2024, raising $73 million at a valuation of $520 million. The round underscored investor confidence in the company's AI-powered search engine, which synthesizes responses from current web content with cited sources. This funding occurred during a period of rapid expansion for Perplexity, which had launched its search engine in December 2022 and attracted millions of users within months.

The Series B round followed an earlier funding phase in early 2024, when Perplexity had raised $165 million in total funding, achieving a valuation of over $1 billion. The 2024 Series B specifically highlighted the company's ability to attract significant capital despite intense competition in the [generative-ai](https://www.wikiprompt.org/wiki/generative-ai) space and ongoing legal controversies. Investors in Perplexity have included notable figures such as Jeff Bezos, Tobias Lütke, Nat Friedman, and companies like Nvidia and Databricks, though the Series B round itself was led by other backers.

## Funding Context and Valuation

Perplexity's Series B in 2024 was part of a broader trajectory of escalating valuations. After the $73 million round at $520 million, the company continued to raise capital aggressively. By April 2024, Perplexity had secured $165 million in cumulative funding, pushing its valuation past $1 billion. Subsequent rounds saw even larger sums: a $500 million round in June 2025 valued the company at $14 billion, and by early 2026, a Series E-6 round brought the valuation to $21.21 billion. The 2024 Series B thus represented a critical inflection point, transitioning Perplexity from a startup to a major player in the [artificial-intelligence](https://www.wikiprompt.org/wiki/artificial-intelligence) industry.

The funding enabled Perplexity to scale its infrastructure, develop proprietary models like Sonar (based on Llama 3.3) and R1 1776 (based on DeepSeek R1), and expand its product line. It also supported the launch of features such as Internal Knowledge Search, a Search API, and a Shopping Hub launched in November 2024 with backing from Amazon and Nvidia.

## Product Development and Expansion

Following the Series B, Perplexity accelerated product innovation. In October 2024, it introduced finance-focused features, including stock price tracking and earnings data, sourced from Financial Modelling Prep. In January 2025, the company launched Perplexity Assistant, an AI tool capable of performing tasks like using rideshare apps or identifying songs, with context maintenance across actions. The assistant also leveraged the phone's camera to answer questions about surroundings or on-screen content, though it remained in development with some features requiring workarounds.

In July 2025, Perplexity launched Comet, an AI browser based on Chromium, initially exclusive to top-tier subscribers but later made freely available in October 2025. The browser integrated Perplexity's search engine, reinforcing its ecosystem. In February 2026, the company unveiled Perplexity Computer, a general-purpose AI agent designed to autonomously execute multi-step tasks using multiple [large-language-model](https://www.wikiprompt.org/wiki/large-language-model)s and specialized subagents. An extension, Personal Computer, followed in April 2026, operating on users' local devices.

## Leadership and Strategic Moves

Aravind Srinivas, co-founder and CEO, led the company through this growth. With prior research positions at [openai](https://www.wikiprompt.org/wiki/openai) and [google-deepmind](https://www.wikiprompt.org/wiki/google-deepmind), Srinivas brought deep expertise in [machine-learning](https://www.wikiprompt.org/wiki/machine-learning). In a March 2026 All-In podcast episode, he described incoming AI-related layoffs as a "glorious future," suggesting they would free people from unwanted jobs and enable entrepreneurship. This comment sparked debate about the societal impact of [generative-ai](https://www.wikiprompt.org/wiki/generative-ai) on employment.

Strategically, Perplexity pursued bold initiatives. In January 2025, it submitted a merger proposal for TikTok US, days before a potential U.S. ban. In August 2025, it bid $34.5 billion to purchase Chrome from Google, arguing the sale could resolve antitrust litigation. In December 2025, Cristiano Ronaldo took an undisclosed stake and entered a global brand partnership. In January 2026, Perplexity committed $750 million over three years to Microsoft Azure for GPU capacity. By February 2026, it shifted to a subscription-first model, discontinuing AI-integrated advertising to preserve user trust.

## Legal and Ethical Controversies

Perplexity faced significant legal scrutiny during this period. In June 2024, Forbes publicly criticized the company for using its content without proper attribution, alleging that Perplexity published a story largely copied from a proprietary Forbes article. This was part of broader allegations from media organizations including the BBC, Dow Jones, and The New York Times, who accused Perplexity of copyright infringement, unauthorized content use, and trademark issues.

Separate analyses by Wired and Cloudflare revealed that Perplexity used undisclosed web crawlers with spoofed user-agent strings to scrape websites that explicitly blocked such activity. These practices raised ethical questions about the balance between AI innovation and content creator rights, a recurring theme in the [artificial-intelligence](https://www.wikiprompt.org/wiki/artificial-intelligence) industry.

## Industry Impact and Competition

Perplexity's rise positioned it as a challenger to established search engines and AI companies. Its search engine, which synthesizes responses with cited sources, offered an alternative to traditional link-based results. The company competed with [openai](https://www.wikiprompt.org/wiki/openai)'s ChatGPT and [anthropic](https://www.wikiprompt.org/wiki/anthropic)'s Claude, as well as tech giants like [google-cloud](https://www.wikiprompt.org/wiki/google-cloud) and [amazon-web-services](https://www.wikiprompt.org/wiki/amazon-web-services) in the broader AI infrastructure space.

The Series B funding allowed Perplexity to invest in [neural-network](https://www.wikiprompt.org/wiki/neural-network) research and [transformer](https://www.wikiprompt.org/wiki/transformer) architectures, though it relied heavily on external models like GPT-5.4, Claude 4.6, and Gemini 3.1 Pro for its Pro tier. Its own models, Sonar and R1 1776, demonstrated in-house capabilities, but the company's dependence on third-party [large-language-model](https://www.wikiprompt.org/wiki/large-language-model)s remained a strategic vulnerability.

## Future Outlook

As of early 2026, Perplexity's valuation of $21.21 billion reflected investor optimism about its growth trajectory. The company's subscription-first model, announced in February 2026, aimed to build sustainable revenue while maintaining user trust. However, legal challenges and ethical controversies continued to pose risks. The outcome of antitrust cases, such as the potential Chrome sale, could reshape its competitive landscape. Perplexity's ability to innovate while navigating these challenges would determine its long-term position in the rapidly evolving [artificial-intelligence](https://www.wikiprompt.org/wiki/artificial-intelligence) market.

The 2024 Series B round, though modest compared to later funding, was a pivotal moment that enabled Perplexity to scale, diversify products, and pursue ambitious strategic goals. It marked the company's transition from a promising startup to a major player, setting the stage for its subsequent growth and controversies.
