Respond.io is pushing AI agents deeper into every stage of the customer conversation.
Respond.io is an omnichannel customer-messaging platform layering AI agents (text and voice) over WhatsApp, Facebook, and other channels. Recent releases sharpen agent context-awareness, add conversation attribution and auto-close with AI summaries, and extend integrations like Cal.com, tightening the loop between automation, reporting, and human handoff.
Krisp opens a second front: Voice Security to defend contact centers against AI voice fraud.
Krisp has fully repositioned around Call Center AI and ships nearly every week. The defining recent move is Krisp Voice Security — a new product line with deepfake detection and agent-voice protection — layered on top of a steady cadence of Voice Translation, Speech Analytics, and admin-control work. The consumer noise-cancellation roots have receded into the background; this now reads as a contact-center platform.
Respond.io is an omnichannel customer-messaging platform layering AI agents (text and voice) over WhatsApp, Facebook, and other channels. Recent releases sharpen agent context-awareness, add conversation attribution and auto-close with AI summaries, and extend integrations like Cal.com, tightening the loop between automation, reporting, and human handoff.
The product is making its AI agents more situationally aware: recognizing assignment, reopened conversations, and recently transferring live calls to humans, while building the reporting and attribution scaffolding around them. The direction is autonomous agents that handle more of the conversation lifecycle, escalating to humans only when needed.
Expect respond.io to keep widening where AI agents can act on their own, with more event triggers, richer handoff logic, and analytics tying agent activity to conversion. The 5 August 2026 webhook-domain deprecation will also force one-time integration cleanup across customer accounts.

Two arcs are compounding. One deepens the analytics and translation core — broader languages, CRM-aware Speech Analytics via Salesforce, real-time oversight of translated calls. The other establishes a security posture aimed squarely at AI voice fraud. Krisp is moving from 'make calls clearer' to 'make calls trustworthy and measurable,' with admin and audit controls maturing alongside both.
Voice Security most likely expands beyond deepfake detection toward broader fraud and identity tooling, and the CRM-integration pattern started with Salesforce extends to more systems feeding Speech Analytics. Both follow directly from the launch and integration entries in this feed.
