About DeepMark

GPAgent's own fund-neutral profile, written from public information. Updated Sep 29, 2026.

Summary

DeepMark embeds a machine-readable identity signal directly into AI-generated audio at the moment of production, surviving VoIP, codecs, and the phone network intact. Banks, call centers, and end recipients can verify in real time that a call originated from an authorized AI agent, replacing trust that previously depended on metadata that gets stripped in transit. The same embed-and-verify flow also marks AI-generated images and video for regulatory compliance, including EU AI Act transparency obligations.

Go-to-market

DeepMark targets banks, call centers, and enterprises running AI voice agents, offering a demo-request entry point and API-level integration into existing infrastructure.

A live watermark inside AI voice that survives phone calls

DeepMark is the authentication layer for AI voice. When an AI agent speaks, we embed a compact, machine-readable ID directly into the audio, not in metadata, which gets stripped the moment a file is touched. The ID resolves to a trust record, so a bank, a call center, or the person on the line can verify in real time who the agent is.
