Telephony for the Builders.
We built Telephony.io because enterprise telecom APIs are too complex and expensive. We believe in raw primitives, fair pricing, and 3-second reliability.

Our Values
The principles that guide our product decisions.
Speed to Lead
Every second counts. If it's not instant, it's broken. We optimize for millisecond latency at every layer.
Developer First
APIs should be typed and intuitive. SDKs shouldn't be an afterthought. We build the tools we want to use.
No Bloat
We don't sell CRMs; we sell the pipe. We do one thing extremely well: Programmable Communication.
