Company information
The facts on file
- Description
- Sierra is an enterprise conversational-AI platform that builds autonomous customer-service agents for voice, chat, email and messaging, running alongside an existing helpdesk rather than replacing it. Founded in 2023 by Bret Taylor and Clay Bavor, it targets large consumer-facing enterprises with high ticket volume and claims to serve over 40% of the Fortune 50. All contracts are custom-quoted through a sales-led process with an outcome-based (per-resolution) pricing philosophy and no published prices.

- Regulatory
- Sierra's own trust page states commitment to SOC 2, HIPAA, GDPR, PCI, FedRAMP High, CCPA, CSA STAR, ISO 27001 and ISO 42001, with automatic encryption and masking of PII and no data sharing between customers; third-party corroboration confirms ISO 27001 and ISO 42001 certification and no cross-organisation model training. One retrieved third-party source conflicts, listing only SOC 2 Type II plus enterprise HIPAA BAAs and stating that ISO 27001 and PCI-DSS Level 1 are not evidenced publicly, and that audit logs are conversation-scoped rather than full reasoning traces. Deployment is Sierra's managed cloud with US and EU regions on enterprise plans; on-prem is not offered. Regulated buyers should request the actual certificates and audit reports.
