Sierra is an enterprise platform for building and deploying AI customer service agents across chat, voice, email, SMS, and WhatsApp. Its agents can take real backend actions (process returns, update subscriptions, manage cancellations) by connecting to enterprise systems via API. Sierra combines generative AI for fluid conversation with deterministic rule-based logic to prevent hallucinations on business-critical decisions. Customers include Rocket Mortgage, Gap Inc., SoFi, and Sutter Health. Pricing is outcome-based (per successful resolution) and entirely enterprise-custom. Key features: - Autonomous agents handling end-to-end customer service across chat, voice, email, SMS, and WhatsApp - Real backend action execution: returns, subscription changes, cancellations via API integrations - Hybrid generative + deterministic logic to reduce hallucinations on rule-bound decisions - Built-in QA workflows with full reasoning transparency for every interaction - Multilingual and multichannel support - Outcome-based pricing: charges per successful resolution, not per seat or query
Enterprise-only, no public pricing. Estimated year-one cost: $200,000-$350,000+. Setup fees of $50,000-$200,000. Ongoing pricing is outcome-based (per resolved interaction). No free trial or self-serve signup.
