Some of the world’s largest companies build their agents on Sierra: hundreds of people working inside a single agent, across hundreds of journeys, serving millions of customers.

It catches the issues that are easy to miss and expensive to ship: a tool your prompt references but never made available, conflicting instructions to the agent, a lookup tool doing an action tool’s job, a response that works on screen but falls apart on a call, or a sensitive-data lookup with insufficient authentication.

A large airline, travel marketplace, and fintech company are already using split traffic to control how rollouts reach their customers.
