**Sierra** is an enterprise-grade conversational AI platform designed to automate customer service interactions through autonomous AI agents. Founded by Bret Taylor (former co-CEO of Salesforce) and Clay Bavor (former Google VP), it focuses on high-reasoning capabilities rather than simple scripted chatbots. ### Core Functionality * **Autonomous Problem Solving:** Unlike traditional bots, Sierra’s agents use Large Language Models (LLMs) to reason through complex customer inquiries, perform multi-step tasks, and access company databases to provide specific answers. * **Systems Integration:** It connects directly to back-office systems (e.g., Salesforce, Shopify, Zendesk) to take actions such as processing returns, modifying subscriptions, or tracking shipments. * **Brand Alignment:** The platform allows companies to define a specific "personality" and set of guardrails to ensure the AI reflects the brand’s tone and policies accurately. ### Competitors Sierra competes primarily in the high-end enterprise conversational AI market: * **Zendesk AI & Salesforce (Agentforce):** Incumbent CRM platforms offering built-in AI agents. * **Intercom (Fin):** A popular AI customer service tool for mid-market and enterprise firms. * **Ada:** An automated customer service platform focused on omnichannel AI integration. * **Forethought:** An AI platform focused on the full customer support lifecycle. ### Pricing Model Sierra does not publish public list pricing. It follows an **Enterprise SaaS** model, typically involving: * **Usage-based or Outcome-based pricing:** Charges are often tied to the volume of successful resolutions or interactions handled by the AI. * **Annual Contracts:** Custom contracts based on the scale of integration and support requirements. ### Notable Customers Sierra has secured partnerships with major consumer brands, including: * **WeightWatchers** * **Sonos** * **Casper** * **SiriusXM** * **Oura**

Sierra is an **enterprise conversational AI platform** for customer experience automation: it lets companies deploy a single branded agent across **chat, SMS, WhatsApp, email, voice, and ChatGPT**, and those agents can do more than answer questions by taking actions such as processing returns, updating subscriptions, and handling other backend workflows.[1][7] It competes with enterprise customer-support and conversational-AI platforms such as **Voiceflow, eesel AI, Forethought, Ada, LivePerson, Intercom, and conversational-agent vendors focused on CX automation**; several reviews also position Sierra against broader customer-service automation tools rather than simple chatbots.[6][11][15] Its pricing model is **not public list pricing**; Sierra is described as using **custom, outcome-based pricing**, where customers pay based on successful business outcomes or resolved issues rather than per seat or per message.[3][6][8] Notable publicly named customers include **WeightWatchers, Sonos, ADT, SiriusXM, Casper, Chime, Cigna, Nordstrom, Nubank, Ramp, Rivian, Rocket Mortgage, Singtel, Sutter Health, and Wayfair**.[3]

Instead of charging per seat or per message, Sierra typically charges based on successfully resolved customer issues, aligning its cost with the value/savings provided to the enterprise. ### Notable Customers Sierra focuses on large-scale consumer brands. Its public client list includes: * **Sonos** * **WeightWatchers** * **SiriusXM** * **Casper** * **Oura**
