Overview

Front

Front transforms your traditional email inbox into a powerful customer operations platform. Instead of juggling disconnected tools, you can manage all your communication channels—email, SMS, live chat, and social media—in one collaborative space. You can assign messages to teammates, chat internally on customer threads without forwarding emails, and use shared drafts to ensure every response is perfect before it goes out.

The platform helps you eliminate the chaos of BCCs and forwarded threads while providing deep visibility into team performance. You can automate repetitive routing tasks and integrate your CRM data directly into your inbox so you always have context. It is designed for teams that need the efficiency of a help desk with the personal touch of a standard email client.

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.
