Sent provides a single API that intelligently routes messages to the channel most likely to deliver—SMS, WhatsApp or RCS—based on real-time AI models that determine availability and optimal channel. The platform reaches more than 1 billion unique phone numbers through direct relationships with 75+ carriers and is used by over 20,000 developers and product teams. Sent reports 99.9% uptime, routing decisions made in real time with end-to-end delivery typically under 200ms, and customers cutting messaging costs 70–80% versus SMS-only approaches. The company recently became a licensed telecom carrier in the United States and is SOC 2 Type 2 compliant. Sent positions itself as infrastructure for an agentic messaging era as AI agents increasingly initiate business-to-consumer conversations and lists customers who have migrated from incumbents like Twilio to its platform.
