Overview
Nextiva
Nextiva is a unified communications platform that brings your phone, video, and messaging together in a single interface. Instead of juggling multiple apps, you can manage all your business conversations from your desktop or mobile device. It helps you eliminate communication silos by connecting your team through internal chat and providing a clear view of every customer interaction across different channels.
You can easily set up toll-free numbers, professional auto-attendants, and advanced call routing to ensure your customers always reach the right person. The platform also includes built-in productivity tools like screen sharing and task management. It scales effectively for any business size, offering various service tiers that integrate with your existing tools like Microsoft Outlook and Google Workspace.
Sierra
Sierra is a conversational AI platform that helps you transform customer service from simple chat into autonomous problem-solving. Instead of basic bots that just answer questions, you can build AI agents that actually perform tasks—like upgrading a subscription, tracking a complex shipping route, or managing a return—by connecting directly to your existing enterprise systems and data.
You can ensure your AI agent stays on brand and follows your specific business logic through a robust reasoning engine. The platform focuses on high-quality, human-like interactions that reduce the need for manual intervention while improving customer satisfaction. It is designed for consumer-facing brands that need to scale their support operations without sacrificing the nuance and personality of their brand identity.
