ElevenLabs Staff to Sell Shares at $6.6 Billion Valuation

ElevenLabs, the fast-growing voice cloning AI startup, is allowing employees to sell shares at a $6.6 billion valuation, double its January 2024 value of $3.3 billion, according to Bloomberg News. The move highlights the ongoing competition among AI firms to retain top talent by offering stock liquidity.

The tender offer will enable staff who have worked at the company for at least a year to sell up to $100 million worth of shares, giving them an opportunity to cash out while allowing investors to boost stakes. Sequoia Capital and Iconiq are leading the deal, joined by Andreessen Horowitz and other backers.

Founded by Piotr Dabkowski (ex-Google) and Mati Staniszewski (ex-Palantir), ElevenLabs has seen explosive growth. Its headcount jumped from 77 employees to 331 in a year, while annualized recurring revenue surged from $100 million in October 2024 to $200 million in mid-2025. The company aims to hit $300 million by year-end.

The valuation leap puts ElevenLabs among the most valuable AI startups in the world. It comes as OpenAI also explores an employee stock sale that could value it at $500 billion, underscoring how AI’s growth is reshaping private markets.

FBI Warns AI-Generated Voices Used to Impersonate Senior U.S. Officials in Cyber Campaign

The FBI has issued a public warning that malicious actors are leveraging AI-generated voice messages and text to impersonate senior U.S. government officials, targeting both current and former federal and state officials in a sophisticated social engineering campaign.

According to the FBI’s announcement on Thursday, the aim of the scheme is to:

  • Gain access to personal accounts of government officials

  • Target additional contacts once access is gained

  • Harvest sensitive information or even solicit funds fraudulently

How the Scheme Works:

  • Attackers initiate text message conversations to build rapport with the targets.

  • Once trust is established, they urge the recipient to switch to another platform, often linking to a hacker-controlled website designed to harvest credentials like usernames and passwords.

  • In some cases, attackers use AI-generated voice clips to convincingly impersonate the tone and mannerisms of known officials.

Threat Scope:

The FBI has not disclosed how many individuals have been targeted or whether the actors are financially motivated cybercriminals or state-aligned entities. The use of generative AI makes attribution and detection more difficult, and the agency continues to assess the full scope of the threat.

This follows a December 2024 warning from the FBI regarding the broader use of AI-generated contentincluding text, audio, images, and videoto commit crimes such as fraud, extortion, and identity theft.

Broader Implications:

The campaign underscores the growing threat of generative AI in cybercrime, particularly in impersonation and phishing-style attacks aimed at high-value targets. Government agencies and private sector organizations are now being urged to:

  • Strengthen multi-factor authentication

  • Train personnel to recognize AI-driven impersonation attempts

  • Avoid clicking on unsolicited links or moving conversations to unknown platforms

As AI tools become more accessible, security experts warn that digital impersonation will become an increasingly common tactic for attackers seeking access to sensitive systems or socially engineered pathways into secure environments.

ElevenLabs Secures $180 Million in Series C Funding, Valuation Hits $3.3 Billion

Voice AI startup ElevenLabs announced on Thursday that it has raised $180 million in a Series C funding round, bringing the company’s valuation to $3.3 billion, tripling its previous worth. The round was co-led by Andreessen Horowitz and Iconiq Growth, with participation from new investors such as NEA, World Innovation Lab, Valor, Endeavor Catalyst Fund, and Lunate.

The surge in investment comes as venture capitalists look to capitalize on the growing commercial potential of generative AI products following the success of OpenAI’s ChatGPT. Based in London, ElevenLabs plans to use the new funds to further research into more expressive and controllable voice AI, create new products, and expand its tools for developers and businesses.

Since its founding in 2022, ElevenLabs has raised a total of $281 million. The company offers AI-generated voice tools that can create voices in different languages, accents, and emotional tones. CEO Mati Staniszewski emphasized that the goal of the funding is to create digital interactions that feel as natural and effortless as human conversations.

In 2024, ElevenLabs expanded its product offering to include speech generation, voice design, sound effects, and AI-driven dubbing in 32 languages. It has also forged partnerships with major publishers like The New Yorker, The Washington Post, and The Atlantic, as well as gaming studios such as Paradox and Cloud Imperium Games.

Existing investors such as Sequoia Capital, Salesforce Ventures, Smash Capital, and SV Angel are also increasing their backing.
