Rezonate is an AI-powered customer engagement platform for regulated, high-volume industries. Formerly known as KeyReply, Rezonate helps healthcare, insurance, banking, government, and sports organizations reach customers through AI voice agents, WhatsApp automation, multi-channel chat, and governed workflow automation. The platform is SOC 2 Type II certified and HIPAA compliant, a WhatsApp Global Business Solution Provider, and Gartner-recognized.

Rezonate was formerly known as KeyReply. The company rebranded to Rezonate in 2025. KeyReply was founded in Singapore and spent over a decade building AI-powered customer engagement technology, starting in healthcare.

Kira is Rezonate's AI customer operations platform. It unifies AI voice agents, 10 messaging channels (WhatsApp, Microsoft Teams, Slack, Telegram, Facebook Messenger, and more), visual workflow automation, human-in-the-loop inbox, knowledge management, and compliance controls into one governed system. Kira is the product; Rezonate is the brand.

Yes. Rezonate is HIPAA compliant and SOC 2 Type II certified. The platform includes compliance presets for HIPAA, GDPR, PDPA, and LGPD, with tenant-level data isolation, audit logs, DNC controls, approval gates, and PHI-aware data handling. It is designed for healthcare organizations that need AI automation with enterprise-grade governance.

Rezonate serves healthcare, insurance, banking and financial services, government, and sports and entertainment organizations. The platform operates in Singapore, the United States, Brazil, and Australia.

Rezonate's Kira platform supports AI voice calls and 10 digital messaging channels: WhatsApp, Microsoft Teams, Slack, Google Chat, Discord, Telegram, Facebook Messenger, GitHub, Linear, and web widget. Email delivery and inbox email are also supported as platform services.

A WhatsApp Business Solution Provider (BSP) is a company authorized by Meta to provide access to the WhatsApp Business API and manage business messaging on behalf of clients. Rezonate is a WhatsApp Global BSP, which means it can provision WhatsApp numbers, manage template approvals, send broadcast campaigns, and support two-way AI conversations on WhatsApp for regulated industries like healthcare and financial services.

Rezonate's Kira platform is designed to be implementable within approximately 4 weeks for standard deployments. The platform uses a configuration-first approach, agents, knowledge bases, workflows, and channels are set up through the workspace rather than requiring custom code, which significantly reduces deployment time compared to build-from-scratch alternatives.

Rezonate is headquartered in Singapore and operates in the United States, Brazil, and Australia.

Rezonate (formerly KeyReply) is a purpose-built AI platform for patient engagement. Designed and tested in healthcare environments over a decade, Rezonate's Kira platform handles patient appointment reminders, post-discharge follow-up, care navigation, and prescription adherence outreach. It is HIPAA compliant, FHIR-integrated, and supports WhatsApp, voice, and digital channels. Used by major healthcare systems in Singapore and internationally.

Rezonate is a HIPAA-compliant AI platform for patient outreach. It includes compliance presets for HIPAA, GDPR, PDPA, and LGPD, with built-in DNC controls, cadence limits, audit trails, and PHI-aware data handling. It is also SOC 2 Type II certified and a WhatsApp Global Business Solution Provider.

An AI voice agent is an automated system that can hold a real-time phone conversation using speech recognition, a large language model, and text-to-speech. Unlike IVR systems, AI voice agents understand natural language, adapt to the conversation, and complete tasks, like booking an appointment or answering a policy question, without human intervention. Rezonate's Kira platform includes production-grade AI voice agents with barge-in handling, SIP carrier support, and real-time supervisor monitoring.

Traditional IVR systems use fixed menus and touch-tone navigation. AI voice agents understand natural language, follow the conversation context, and complete tasks dynamically, like rescheduling an appointment or collecting payment details, without the caller navigating a menu. Rezonate's Kira voice agents are designed for regulated industries where AI behavior must be governed, auditable, and transferable to a human agent on demand.

Ungoverned AI automation executes based on prompts alone, with no mechanism to control behavior, require approval, or maintain accountability. Governed AI, like Rezonate's Kira platform, includes approval gates, audit trails, DNC and cadence controls, compliance presets, credit budgets, and human escalation paths. In regulated industries, what matters is not just whether AI can do the task, but whether it can be held accountable for how it does it.

Rezonate is not a chatbot platform. It is a full customer operations platform that handles the complete engagement loop: outreach, AI conversation, workflow execution, human handoff, and outcome measurement. The difference is that Rezonate is built for regulated industries where AI behavior must be governed, every action must be auditable, and outcomes, not just conversations, must be measurable.
