Sierra (Bret Taylor's voice-agent platform) is the most credible direct competitor — well-funded, well-engineered, multi-vertical. Cresta covers contact-center AI broadly. Both can eventually cover Reg E, Reg BI, and FINRA scope. The buy-vs-build window for mid-sized banks, credit unions, and independent broker-dealers is the same 24-36 months: by the time Sierra ships a regulated-financial-specific pack with FINRA capture wired in, the in-house Wells/JPM/BofA builds will also be live.
Where Sage Voice wins inside the window:
Kill condition. If Sierra ships a financial-services vertical pack with Reg E + Reg BI capture, or a core-banking vendor (FIS, Fiserv, Jack Henry) ships a native voice-AI module, the financial vertical compresses into an acquihire window faster than insurance or healthcare.
31 CFR § 1020.220 (banks); § 1023.220 (broker-dealers); FINRA Rule 2090. Structured CIP fields with audit-log linkage. Tenant supplies documentary or non-documentary verification.

12 CFR Part 1005. Disclosure summary delivered on EFT enrollment; full Reg E disclosures mailed/emailed via the tenant's downstream pipeline. Acknowledgement timestamped.
17 CFR § 240.15l-1 (Reg BI); § 240.17a-14 (Form CRS). Broker-dealer suitability capture; Form CRS link delivery and receipt confirmation in the audit log.

Full SSN, PAN, and account numbers are captured via keypad DTMF, never via voice. The audit log never contains these values in plaintext. For tenants with PCI DSS v4.0 scope, Sage Voice operates as a P2PE channel — cardholder data does not enter the Worker memory in plaintext.
The orchestrator (Retell or Vapi) gates the DTMF capture window; the Worker only sees a redacted token. The tenant's downstream PCI-scoped system receives the actual values via a separate secure channel and is the system of record for cardholder data.
CIP + CDD capture, OFAC screening, GLBA privacy notice. Hand off to banker for funding and signature card.
FCRA-noticed credit pull authorization. Qualification ranges only — no commitment. Adverse-action notice triggered on tenant decline.
Verify recent transactions via DTMF; escalate on confirmed fraud. Reg E error-resolution timeline started in the audit log.
Periodic-review documentation. CIP re-verification. Enhanced due diligence on threshold-triggering accounts.
