Bland AI
Purpose-built outbound AI calling with the clearest compliance posture in the category.
Bland is the only vendor we reviewed that publishes a flat per-minute rate, states daily call and concurrency ceilings for every tier, and holds SOC 2 Type II, a HIPAA BAA, GDPR and PCI DSS at once. It also offers on-prem/VPC deployment, which almost nothing else at this price does. You can start with no credit card. It loses points only on ecosystem breadth: there is less turnkey CRM tooling than platforms built around integrations.
Synthflow
Enterprise-only voice AI with ISO 27001 and EU hosting — and a $30,000 annual floor.
Synthflow has moved upmarket and now sells enterprise contracts only, starting at $30,000 per year. To its credit it publishes that floor, which most sales-gated vendors will not do. The compliance stack is the strongest here alongside Bland — SOC 2, HIPAA, GDPR and ISO 27001, with EU or US hosting. But there is no self-serve path at all: you cannot place a test call without going through sales.
