Sent Raises $12M Series A to Supercharge AI Messaging Infrastructure

Sent, a unified API for reaching users over SMS, WhatsApp, or RCS through one integration, reported an oversubscribed $12 million Series A. The funding cycle adds to its shift toward licensed telecom infrastructure in the United States, where it can allocate numbers directly.

According to the company, its platform routes messages based on channel availability and channel optimality, so a message is sent to the channel a recipient can reach. Sent also described built-in compliance features, carrier relationships, and deliverability performance metrics tied to routing decisions made in real time.

Sent said the API determines, in real time, which platforms can receive a message to a number and which channel is optimal when the number is reachable on WhatsApp, SMS, and RCS. It reported mapped channel preferences across direct relationships with 75+ carriers, support for one API for SMS, WhatsApp and RCS, and routing configured for end-to-end delivery typically under 200ms, with 99.9% uptime.

The company said the Series A was led by Companyon Ventures with participation from Bessemer Venture Partners, UIF and CP Overture. Sent also said the round included pre-seed angel investors from Clay, Eleven Labs and Attentive, and that it will use the funding to expand its direct carrier network and deepen its AI-native, agent-facing messaging infrastructure.

“AI agents will soon send more business messages than people do, and the infrastructure beneath them is not ready,” said Daniel Vataj, co-founder and CEO of Sent. “The legacy model asks every company to choose a single channel, integrate and continuously manage it, and hope messages arrive. Sent reverses that model: tell us who you need to reach, and our platform determines where they are reachable, routes the message through the right channel, and handles the compliance and carrier complexity underneath it.”

“The next generation of messaging infrastructure has to make complexity disappear without sacrificing control. Routing, reliability and compliance need to work together at the infrastructure layer, so developers can integrate once and trust that every message and notification delivers. That is the company we set out to build.”

“AI agents will soon send more business messages than people do, and the infrastructure beneath them is not ready,” said Daniel Vataj, co-founder and CEO of Sent.
