AgentPhone

AgentPhone gives every AI agent its own dedicated phone number, enabling autonomous agents to call businesses, send and receive SMS/iMessage/RCS/WhatsApp, and complete real-world tasks without human intermediaries. The company abstracts away telecom compliance complexities (STIR/SHAKEN, A2P 10DLC, carrier registration) into a single developer API and unified webhook. Founded in 2026 and backed by Y Combinator's Spring 2026 (P26) batch, AgentPhone targets developers and engineering teams building autonomous AI agents. Its thesis is that the $2 trillion global telecom industry was built for humans, and AI agents are currently blocked from acting in the real world because they lack a phone identity.
