Sierra
PaidConversational AI agents that handle customer service for large brands
What is Sierra?
Sierra is a platform for building branded AI agents that talk to customers over chat and phone. It was founded by Bret Taylor and Clay Bavor and is used by large consumer brands to handle tasks like returns, subscription changes and troubleshooting.
Each Sierra agent is configured with the company's tone, policies and access to systems such as order management and CRM. The platform includes tools for testing agents against simulated conversations, monitoring live quality and rolling out changes safely.
Sierra prices on outcomes, so customers pay when the agent completes a task such as resolving a case. It acquired the French workflow startup Fragment in 2026 to extend its agents into more back-office processes.
