What is Eleven Labs?

ElevenLabs is a software company founded in 2022 that develops natural-sounding speech synthesis and voice AI tools, including text-to-speech, voice cloning, dubbing, and conversational AI agents. The recent thread in commentary is its rapid commercial expansion, particularly into government contracts, and its position ahead of rival voice AI startups.

Release history

  • Aug 2026 - ElevenLabs told Patrick Collison it was blocking 2,000 free trial abusers per day.

Worth quoting

Harry Stebbings on Sequoia's awkward dual position in the Sierra vs. Eleven Labs rivalry.

“I think Sierra running behind them chasing and they're doing a decent job of it but they've got Brett and they've got Sequoia and Green Oaks and every royalty of Silicon Valley behind them and they're still running behind chasing 11 Labs with Sequoa kind of pretending to be neutral because they're in both of them which is incredibly challenging.”

Company & tool watch

Eleven Labs has secured government buyers across all major Western democracies in just three months, signaling rapid enterprise and public-sector penetration in voice AI.

“Now 11 Labs is an unstoppable machine at this point to the point where it has government buying across all of the large major western democracies. Actually it's insane the government buying they have and they started 3 months ago.”

Contrarian take

Sierra trails Eleven Labs in the voice-AI market despite having Bret Taylor, Sequoia, and Greenoaks behind it, suggesting financial and reputational backing alone cannot close a product lead.

“I think Sierra running behind them chasing and they're doing a decent job of it but they've got Brett and they've got Sequoia and Green Oaks and every royalty of Silicon Valley behind them and they're still running behind chasing 11 Labs with Sequoa kind of pretending to be neutral because they're in both of them which is incredibly challenging.”
