Perplexity, an artificial intelligence-driven search engine, has closed its fourth funding round this year, tripling its valuation to $9bn as it seeks to compete with offerings from Google and OpenAI.
The $500mn round was led by Institutional Venture Partners. Previous investors have included SoftBank’s Vision Fund 2, Nvidia and Amazon founder Jeff Bezos, as well as several prominent names from the AI industry such as OpenAI co-founder Andrej Karpathy and Meta’s chief AI scientist Yann LeCun.
The San Francisco-based group has grown rapidly this year, with its product receiving hundreds of millions of queries a month. It has 15mn monthly active users with most of that traffic coming from the US.
It is seeking to capitalise and improve on the search advertising system pioneered by Google, in which marketers bid to have a sponsored link placed against search queries. It is in talks with major brands to pilot advertising on its platform.
In a sign of growing competition in the space, AI companies have recently targeted the search market by linking up chatbots to the internet. This week, OpenAI rolled out web searching for its popular ChatGPT product, while Anthropic’s Claude can perform searches through a feature called “computer use”.
Google and Microsoft, which are leaders in the $300bn digital advertising world, have also recently incorporated large language models, which power AI chatbots and make results more conversational, into their search offerings.
The latest round has pushed Perplexity’s valuation higher by nine-fold since the start of the year, in another sign of how hot start-ups developing new AI tools can draw in hundreds of millions or even billions of dollars in investment.
After OpenAI’s $6.6bn fundraising in October — one of the largest in Silicon Valley — one person close to the company said Perplexity was inundated with unsolicited interest from new investors.
Run by former Google intern Aravind Srinivas, Perplexity raised $250mn this summer, on top of previous funding rounds in January and April.
Perplexity makes money through subscriptions. It says its annualised revenues — a projection of full-year revenues based on extrapolating the most recent month’s sales — have grown from $5mn in January to $35mn in August.
The spate of deals for lossmaking AI start-ups has stoked concern among some investors that rising valuations in the sector show all the hallmarks of a bubble, however. But even those who argue most AI valuations are increasingly detached from reality are willing to stake bets on companies they believe could be winners.
The closing of the round was first reported by Bloomberg.
