What it does

Sierra builds conversational AI agents for large consumer brands. The company was founded in 2023 by Bret Taylor, former co-CEO of Salesforce, and Clay Bavor, formerly of Google, and quickly became one of the highest-profile companies in the AI agent space.

Sierra’s platform lets companies deploy branded AI agents that handle customer conversations over chat and voice, follow company policies, and take actions in backend systems such as order management or subscription changes. The company emphasizes guardrails, brand tone, and outcome-oriented deployments rather than self-serve tooling.

Sierra works with enterprises through a high-touch sales and deployment model, and pricing is negotiated per customer.
