Heymarket layers AI agents and routing on top of its business-messaging core.
Heymarket is a business-messaging platform expanding across channels (now RCS via Twilio) and into AI agents and workflow features like Escalations. The crawled feed mixes real feature announcements with how-to and thought-leadership content.
Krisp adds AI voice-fraud security to its Call Center AI stack
Krisp is expanding its Call Center AI suite well beyond its noise-cancellation roots. Recent releases center on a new Voice Security product line — AI voice-fraud detection with deepfake detection and agent voice verification — plus continued Speech Analytics, Voice Translation (v3, more languages, admin oversight of translated calls), and admin governance controls. It ships on a fast biweekly cadence with monthly recap posts.
Heymarket is a business-messaging platform expanding across channels (now RCS via Twilio) and into AI agents and workflow features like Escalations. The crawled feed mixes real feature announcements with how-to and thought-leadership content.
The product is moving from shared-inbox messaging toward AI-assisted, omnichannel operations — RCS, AI agents trained in-house, escalation routing, and structural tools like conversation tags and webhooks. The direction is a fuller customer-messaging operations layer.
Expect continued investment in AI agents and channel breadth (RCS, voice) on top of the shared-inbox foundation, likely with more routing and automation controls.

It ships on a fast biweekly cadence with monthly recap posts.
Krisp is stacking distinct AI capabilities onto the contact-center seat it already owns — translation, analytics, and now fraud security — moving from a utility into a broader agent-experience and security platform. Voice Security is the strategically new thread; Voice Translation and Speech Analytics are maturing with more languages, deeper analytics, and tighter admin controls.
Expect Voice Security to broaden (more fraud signals, deeper admin and audit tooling) and Voice Translation to keep adding languages, given the steady per-release expansion visible across the feed.
