What AI companies need

Sinch solves all three reasons AI agents struggle at scale

AI and technology companies get blocked by a few predictable problems in their communications stack. Here’s exactly how Sinch fixes each one.

A slow OTP or a laggy voice handoff is instantly visible in an AI product, forcing you to stop and troubleshoot. Sinch’s global infrastructure of direct carrier connections easily handles the jump from a thousand users to millions, so your team can keep building.

Legacy integrations and compliance requirements pile up as platforms mature, and every new vendor adds more to maintain. Sinch unifies messaging, email, voice, and verification under one platform that fits your existing stack.

An AI agent handling verification or a transaction on its own can expose a vulnerability before a person catches it. Sinch’s fraud controls run natively at runtime, so agents call them the same way they call any other tool.
