A line the company declared to usedby itself is marked declared. A signal is never a case study or a vendor listing. Strongest proof first. "Last check" is the later of the line's re-verification and its latest capture. | Tool | Company | Proof | Source | Last check | |---|---|---|---|---| | ElevenLabs | [AudioStack](https://www.usedby.ai/companies/audiostack.md) | Confirmed | [elevenlabs.io](https://elevenlabs.io/blog/audiostack), captured 2026-10-18 | 2026-10-18 | | ElevenLabs | [Bolna](https://www.usedby.ai/companies/bolna.md) | Confirmed | [elevenlabs.io](https://elevenlabs.io/blog/bolna-powers-recruitment-voice-agents), captured 2026-10-18 | 2026-10-18 | | ElevenLabs | [Layer](https://www.usedby.ai/companies/layer.md) | Confirmed | [elevenlabs.io](https://elevenlabs.io/blog/layer), captured 2026-10-18 | 2026-10-18 | | ElevenLabs | [Thoughtly](https://www.usedby.ai/companies/thoughtly.md) | Confirmed | [elevenlabs.io](https://elevenlabs.io/blog/thoughtly), captured 2026-10-18 | 2026-10-18 | | ElevenLabs | [Hedra](https://www.usedby.ai/companies/hedra.md) | Confirmed | [elevenlabs.io](https://elevenlabs.io/blog/hedra), captured 2026-10-18 | 2026-10-18 | | ElevenLabs | [Rosebud AI](https://www.usedby.ai/companies/rosebud-ai.md) | Observed | [elevenlabs.io](https://elevenlabs.io/customer-stories), captured 2026-10-09 | 2026-10-09 | | ElevenLabs | [Cora AI](https://www.usedby.ai/companies/cora-ai.md) | Observed | [elevenlabs.io](https://elevenlabs.io/blog/category/customer-stories) | Not dated | | ElevenLabs | [Notta](https://www.usedby.ai/companies/notta.md) | Observed | [elevenlabs.io](https://elevenlabs.io/blog/category/customer-stories) | Not dated | | ElevenLabs | [ThisGen 911](https://www.usedby.ai/companies/thisgen-911.md) | Observed | [elevenlabs.io](https://elevenlabs.io/customers) | Not dated | | ElevenLabs | [Athos](https://www.usedby.ai/companies/athos.md) | Observed | [elevenlabs.io](https://elevenlabs.io/blog/category/customer-stories) | Not dated | | ElevenLabs | [Zooly](https://www.usedby.ai/companies/zooly.md) | Observed | [elevenlabs.io](https://elevenlabs.io/blog/category/customer-stories) | Not dated | | Resemble AI | [Charisma.ai](https://www.usedby.ai/companies/charisma-ai.md) | Observed | [resemble.ai](https://www.resemble.ai/resources?category=case-studies), captured 2026-10-17 | 2026-10-17 | | Resemble AI | [KomBea](https://www.usedby.ai/companies/kombea.md) | Observed | [resemble.ai](https://www.resemble.ai/resources?category=case-studies), captured 2026-10-17 | 2026-10-17 | | Resemble AI | [Umanitek](https://www.usedby.ai/companies/umanitek.md) | Observed | [resemble.ai](https://www.resemble.ai/), captured 2026-10-17 | 2026-10-17 | | WellSaid | [Waymark](https://www.usedby.ai/companies/waymark.md) | Confirmed | [wellsaid.io](https://www.wellsaid.io/resources/case-studies/how-wellsaid-labs-transformed-waymarks-ai-video-production-platform), captured 2026-10-08 | 2026-10-20 | ## Method Public customer lines of active Voice & audio generation tools at companies classified in Artificial Intelligence. 8 companies that sell software were left out, so a vendor is never counted as a user.
