Voice-native conversational AI agents for customer and employee touchpoints
A voice-native platform for building and orchestrating AI agents, with agent and model selection, rule-based actions, and human-assisted resolution.
Agents are designed to keep listening and understanding through interruptions, background noise, and the unpredictable flow of real conversations.
Layered guardrails at instruction, task, function, and channel level, a proprietary PII-detection LLM, tenant isolation, encryption, and full audit logging.
Deploy agents to digital channels and physical locations — phones, drive-thrus, in-car systems, kiosks, and employee tools — from a single system.

AI-powered customer conversation platform for B2C messaging at scale
Bring WhatsApp, TikTok, Instagram, Facebook, Telegram, email and web chat into one shared inbox so no customer thread gets lost between apps.
AI agents qualify leads, answer routine questions, route to the right teammate and follow up automatically when conversations go quiet.
Track tags, custom fields, lead status and lifecycle stage per contact, and move deals through a pipeline without a separate CRM.
Reach thousands of customers with one message, and capture new leads directly from social ads and website links.
