Telnyx

Provides communications and AI infrastructure primitives for building realtime voice and omnichannel agents, covering telephony, messaging, speech-to-text, text-to-speech, and inference while meeting a 500ms conversational turn budget. Sells to developers, IT and operations teams in B2B companies building contact centers, notifications, and connected fleet applications. Positioned as the only licensed carrier that owns its AI infrastructure end-to-end — private network, GPUs, and edge compute — so every hop between agent and caller is owned.
