ElevenLabs just pulled off one of the year's biggest AI funding rounds, raising $500 million at an $11 billion valuation from Sequoia Capital. The voice AI company has tripled its worth in just 12 months, closing 2025 at $330 million in annual recurring revenue. With Sequoia partner Andrew Reed joining the board and existing investor a16z quadrupling down, the round signals investors are betting big on voice AI becoming the next frontier of human-computer interaction.
ElevenLabs is making a massive bet that voice is just the beginning. The voice AI startup announced today it's raised $500 million in new funding led by Sequoia Capital, vaulting its valuation to $11 billion - more than three times what it was worth just 12 months ago when it hit a $3.3 billion valuation in January 2025.
The round's heavyweight investor lineup tells the story. Sequoia, which participated in ElevenLabs' last secondary tender round, is now leading with partner Andrew Reed joining the company's board. But the real vote of confidence comes from existing backers doubling down hard - a16z quadrupled its investment amount, while Iconiq, which led the previous round, tripled its stake. BroadLight, NFDG, Valor Capital, AMP Coalition, and Smash Capital all piled back in.
New money came from Lightspeed Venture Partners, Evantic Capital, and Bond, though ElevenLabs is keeping some investor names under wraps until later this month. The company's been coy about why, hinting these might be strategic partners rather than pure financial investors. With over $781 million raised to date, ElevenLabs now has serious runway to execute on an ambitious expansion plan.
The numbers backing this valuation are hard to ignore. ElevenLabs closed 2025 at $330 million in annual recurring revenue, according to TechCrunch. Even more striking, co-founder Mati Staniszewski told earlier this year that the company jumped from $200 million to $300 million ARR in just five months. That kind of growth momentum in the enterprise AI space is rare, even in today's frothy market.
