ElevenLabs Agents

Best-in-class generative voice, plus conversational agents across phone, web and apps

About ElevenLabs Agents

ElevenLabs is the reference point for generative voice quality, and its Agents product extends that into conversational agents that talk, type and take action across phone, web and apps, with more than 2 million agents created and 33 million conversations handled. It raised $500M at an $11B valuation in February 2026. Sistava uses voice as one channel attached to an employee that also works over email, Slack, WhatsApp and the browser, sharing one memory across all of them.

Why ElevenLabs dominates voice

Quality, and it is not particularly close. ElevenLabs voices cleared the uncanny valley earlier than competitors and stayed ahead, which matters enormously for phone agents where a synthetic-sounding voice causes people to hang up in the first five seconds. That lead turned into a business: over $330M ARR at the end of 2025, enterprise adoption at Deutsche Telekom and Revolut, and a $500M round in February 2026 led by Sequoia at an $11B valuation, tripling its worth in a year. ElevenLabs Agents extends the voice layer into full conversational agents that handle turn-taking, interruptions and knowledge retrieval, then talk, type and take action across phone, web and apps. More than 2 million agents have been created on it, handling 33 million conversations.

Infrastructure versus employee

ElevenLabs sells the capability. You decide what the agent is for, wire the tools it can call, connect it to your systems, and own the logic around it. That is exactly right if you are building a product with voice in it. Sistava sells the outcome. Voice is a channel bolted onto an employee that already has a role, a memory, a task board and access to your tools. A call it makes updates the same context its emails use, and the leader sees it on the board. Neither replaces the other conceptually. A voice-first company should build on ElevenLabs. A company that wants someone to make the calls should hire rather than build.

Per-minute pricing and when it bites

Roughly $0.10 per minute, or around $0.08 on Business, is competitive and transparent. On low volume it is genuinely cheap: a hundred five-minute calls a month is about $50. It scales linearly, which is the thing to model. A thousand calls a month at five minutes is closer to $500 in conversation cost alone, before whatever you spend on the surrounding stack and the engineering time to build it. A flat plan with a shared credit pool behaves differently: predictable, and covering email and chat from the same budget. Which is better depends entirely on whether voice is your only channel or one of five.
