telnyx

Telnyx is a full-stack communications and AI infrastructure platform that owns its carrier-grade global network from the physical layer through AI inference. The platform provides developers and enterprises with voice AI agents, telephony APIs (voice, SMS, SIP trunking), eSIM, speech-to-text, text-to-speech, and global number management — all running on Telnyx's private fiber network with co-located edge PoPs and GPUs for sub-500ms end-to-end latency. Unlike platforms that layer over third-party infrastructure, Telnyx owns the full stack from bare-metal interconnects to AI runtime, enabling autonomous agent-to-agent orchestration, programmatic compliance (10DLC/KYC), and enterprise security at the network layer. Customers including OpenAI, IBM, Cisco, Microsoft, and Zillow use Telnyx to power healthcare automation, finance workflows, travel booking, logistics, and contact center operations.
