Overview

Stammer is built for the agency rather than the end customer. Chat agents handle websites, Instagram, Facebook and WhatsApp, voice agents take inbound and outbound calls, and the entire dashboard is white-labelled onto the agency’s own domain, so clients never see Stammer.

Pricing usage separately from the platform is the honest part of the model. Agency at $197 and Full SaaS Mode at $497 buy the platform, then messages cost from $0.001 on a small model to $0.03 on Claude 3.7 Sonnet and calls run $0.11 to $0.17 a minute, which lets a reseller price their own margin knowingly rather than guessing at an all-in bundle.

The company reports 35,000 live agents and 12 million conversations, with no-code setup, live chat handoff and daily office hours. Per-message costs on the better models add up fast at volume, a white-label platform means an agency’s client relationships depend on a supplier those clients cannot see, and reselling means owning support for someone else’s software.
