Company profile

researched Sep 2026

RelayVoice is a voice-AI outreach service operated by DemTEC, Inc. The company applies generative and voice AI to outbound communication campaigns on behalf of client organizations, positioning its offering around delivering a client's message to larger audiences at lower cost than manual calling.

The product set covers three main services: an interactive polling tool built on the company's voice AI; patch-through calling, which connects contacted individuals directly to decision-makers for live conversations; and personalized voicemail delivery using ringless voicemail technology combined with AI-generated voice. Engagements are configured per customer, with RelayVoice working with each client to adapt the application of AI to that organization's existing processes and campaign objectives.

Published use cases span sales pipeline generation, fundraising outreach, and call-to-action campaigns intended to activate an existing contact list toward a specific outcome such as booking appointments or attending events.
