Sierra

Enterprise AI agents that act on your behalf

Sierra is a conversational AI platform, co-founded by former Salesforce co-CEO Bret Taylor and former Google executive Clay Bavor, that lets enterprises build customer-facing AI agents matched to their brand voice. It offers Agent Studio, a no-code builder for CX teams, alongside an Agent SDK for developers who want programmatic control, so technical and non-technical teams can work on the same agent. Agents can take real actions — updating accounts, processing orders — rather than only answering questions, and run on a multi-model architecture rather than a single underlying LLM. Sierra targets large, well-known enterprises, with the company stating that more than 40% of the Fortune 50 use its platform, positioning it at the high end of enterprise CX automation alongside competitors like Decagon and Parloa.

Key Features

Agent Studio: A no-code interface letting CX and operations teams design and adjust agent behavior without engineering support.
Agent SDK: A developer-facing toolkit with pre-packaged agent “skills” and connectors for building more customized agents programmatically. Note: access to the SDK and developer docs is gated to contracted enterprise customers rather than offered as a public self-serve API.
Multi-model architecture: Agents route across multiple AI models instead of relying on one provider, which Sierra says improves reliability and lets it match models to tasks.
Guardrails and supervision: Built-in safeguards intended to constrain agent responses and reduce the risk of incorrect or off-brand answers reaching customers.
Simulation and testing: Tools to simulate customer conversations before launch, used to evaluate expected agent performance.
Cross-system action-taking: Agents integrate with backend systems to complete tasks like account updates or order changes, not just generate replies.

Use Cases

For consumer subscription brands: A subscription brand deploys agents to handle plan changes, cancellations, and billing while keeping responses aligned to its brand voice.
For complex regulated workflows: A financial services or healthcare enterprise uses Sierra’s guardrails to let agents handle sensitive tasks like claims status within compliance constraints.
For mixed technical/non-technical teams: An enterprise uses Agent Studio and the Agent SDK side by side so CX operations and engineering can each build at their own level of technical depth.
