About Respond.io
Respond.io is rebuilding around Voice AI Agents — and just gave them a way to escalate.
Respond.io's center of gravity has clearly moved to AI Agents. Recent releases give them multi-model failover, faster GPT-5.4-class responses, awareness of which human agents are online, ad-source context for Meta and TikTok leads, and now real-time handoff from a live AI call to a human. The traditional inbox features (custom Facebook templates, mobile UX, webhook reliability) are still shipping but feel like the supporting cast.
