AI audio models, creative tools, and conversational agents
ElevenLabs
ElevenLabs builds AI audio models and tools for businesses, creators, and developers. ElevenCreative lets creators and marketers generate, edit, and localize speech, music, images, and video across more than 70 languages. ElevenAgents lets businesses deploy voice and chat agents with integrations, testing, and monitoring for customer operations. ElevenAPI exposes its audio models to developers building interactive products. The broader toolkit includes voice cloning, dubbing, transcription, and sound effects.
Founded in 2022, ElevenLabs is led by co-founders Mati Staniszewski, CEO, and Piotr Dąbkowski, CTO. The two grew up together in Poland, where poorly dubbed films inspired their interest in overcoming language barriers. Its voice research addresses both speaker identity and expressive delivery: voice cloning encodes the target speaker’s characteristics, while voice conversion preserves source intonation. Its multilingual dubbing research applies these ideas to carrying a speaker’s voice, emotion, and delivery across languages.
Customers include Deutsche Telekom, Square, and Revolut for enterprise agents, and Duolingo, NVIDIA, and TIME for creative content. The company reported surpassing $500 million in annual recurring revenue during the first four months of 2026. In February 2026, it announced a $500 million Series D at an $11 billion valuation; the round reportedly exceeded $550 million after its third close.

Messages from the stage
Designing spoken interaction
Schaeff’s workshop addresses regional accents, specialized pronunciation, latency, and multilingual transcription limits. Harries adds emotion-aware turn-taking and semantic VAD, while Reeve’s statue demonstration raises questions about culturally appropriate accents and conversational interruption.
Testing an undocumented phone protocol
Starkov describes brute-forcing device commands and investigating settings that vanished after reboot. His account emphasizes validating discoveries through closed-loop experimentation before routing the phone through a Twilio SIP trunk.
Understanding training behavior
Perivolaropoulos’s workshop connects tokenizer and transformer implementation with optimization schedules, validation, overfitting, and initial loss behavior in a small GPT-2-style model built using Torch.
