What does Sierra do?

Sierra is an enterprise-grade AI platform that helps companies build and deploy conversational AI agents for customer service. These agents handle complex customer interactions across multiple channels including chat, SMS, WhatsApp, email, and voice. The platform enables businesses to automate customer support while maintaining personalized, brand-appropriate conversations that can handle everything from simple queries to complex multi-step processes like flight bookings or account management.

The platform stands out with its comprehensive Agent OS, which includes both a no-code Agent Studio for business teams and an Agent SDK for developers. It features sophisticated conversation monitoring, multivariate testing capabilities, and deep integration with existing customer data systems. Unlike simple chatbots, Sierra agents can access real-time customer data, make personalized recommendations, and proactively engage customers based on behavioral signals.

This tool primarily benefits large enterprises with significant customer service operations across retail, financial services, healthcare, and technology sectors. Real-world use cases include handling customer inquiries for Rocket Mortgage, managing subscriber support for SiriusXM, and providing personalized shopping assistance for brands like The North Face and Gap. It's particularly valuable for companies looking to scale their customer service while maintaining quality and personalization.
