integrations
Works with the tools your operator already uses.
Hermes is a single platform — no BYOK, no glue code. We bundle voice, calendar, CRM, billing, and notifications. For tools you can’t replace, we sync.
trusted technologies
The infrastructure we build on, the platforms we integrate with.
Hermes uses best-in-class infrastructure under the hood. Operators see one platform; we manage the upstream complexity.
