NXIVO AI Receptionist

Every missed call costs your business $450 in lost revenue. Nxivo is the AI receptionist that makes sure you never miss one. Nxivo answers every inbound call 24/7 with a natural, conversational voice, books appointments directly to your Google Calendar, and collects payment via Stripe, all during the call, before the caller hangs up.
