A line the company declared to usedby itself, or that it lists as a sub-processor on its own legal page, 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 | |---|---|---|---|---| | Retell AI | [Anker](https://www.usedby.ai/companies/anker.md) | Confirmed | [retellai.com](https://www.retellai.com/case-study/how-anker-transformed-global-customer-support-with-human-quality-al-voice), captured 2026-10-05 | 2026-10-20 | | Retell AI | [Boatzon](https://www.usedby.ai/companies/boatzon.md) | Confirmed | [retellai.com](https://www.retellai.com/case-study/how-retell-ai-became-boatzons-top-performing-employee), captured 2026-10-05 | 2026-10-20 | | Retell AI | [Swtch](https://www.usedby.ai/companies/swtch.md) | Confirmed | [retellai.com](https://www.retellai.com/case-study/how-swtch-keeps-ev-drivers-moving-with-always-on-voice-support-powered-by-retell), captured 2026-10-09 | 2026-10-20 | | Retell AI | [Asbury Automotive Group](https://www.usedby.ai/companies/asbury-automotive-group.md) | Observed | [retellai.com](https://www.retellai.com/customers), captured 2026-10-20 | 2026-10-20 | | Retell AI | [Eufy](https://www.usedby.ai/companies/eufy.md) | Observed | [retellai.com](https://www.retellai.com/customers), captured 2026-10-20 | 2026-10-20 | | Regal | [Angi](https://www.usedby.ai/companies/angi.md) | Confirmed | [regal.ai](https://www.regal.ai/case-study/angi), captured 2026-10-08 | 2026-10-24 | | Regal | [National Energy Equipment](https://www.usedby.ai/companies/national-energy-equipment.md) | Confirmed | [regal.ai](https://www.regal.ai/case-study/national-energy-equipment), captured 2026-10-08 | 2026-10-24 | | Regal | [The Farmer's Dog](https://www.usedby.ai/companies/the-farmer-s-dog.md) | Confirmed | [regal.ai](https://www.regal.ai/case-study/the-farmers-dog), captured 2026-10-08 | 2026-10-24 | | Regal | [Guitar Center](https://www.usedby.ai/companies/guitar-center.md) | Observed | [regal.ai](https://www.regal.ai/customers), captured 2026-10-24 | 2026-10-24 | | PolyAI | [Fogo de Chão](https://www.usedby.ai/companies/fogo-de-chao.md) | Confirmed | [poly.ai](https://poly.ai/customers/fogodechao), captured 2026-10-08 | 2026-10-21 | | PolyAI | [Hawksmoor](https://www.usedby.ai/companies/hawksmoor.md) | Confirmed | [poly.ai](https://poly.ai/customers/hawksmoor), captured 2026-10-08 | 2026-10-21 | | PolyAI | [Foot Locker](https://www.usedby.ai/companies/foot-locker.md) | Observed | [poly.ai](https://poly.ai/), captured 2026-10-21 | 2026-10-21 | | PolyAI | [The Melting Pot](https://www.usedby.ai/companies/the-melting-pot.md) | Observed | [poly.ai](https://poly.ai/resources/case-studies), captured 2026-10-21 | 2026-10-21 | | Replicant | [Fanatics](https://www.usedby.ai/companies/fanatics.md) | Confirmed | [replicant.com](https://replicant.com/case-studies/fanatics), captured 2026-10-08 | 2026-10-21 | | Synthflow | [Nellis Auction](https://www.usedby.ai/companies/nellis-auction.md) | Observed | [synthflow.ai](https://synthflow.ai/pricing), captured 2026-10-16 | 2026-10-16 | | Vapi | [Kavak](https://www.usedby.ai/companies/kavak.md) | Observed | [vapi.ai](https://vapi.ai/customers), captured 2026-10-22 | 2026-10-22 | ## Method Public customer lines of active AI phone & voice agents tools at companies classified in Commerce & Retail.
