Sierra scores A on the Alion truth index (A is best, E worst), measured over 66 open roles re-checked against its own hiring board: 0% look like ghost listings, 30% have gone stale and 0% are the same role posted again. Its roles close in a median of 95 days. It measures how much of what this employer publishes turns into a real, finite search - not the employer as a workplace. How the index is computed
Overview
Sierra is an American artificial intelligence company founded in 2023 by Bret Taylor, the former co-chief executive of Salesforce and chairman of OpenAI, together with a former Google engineering leader. It builds conversational agents that handle customer service interactions end to end for large consumer businesses, resolving issues by acting on the company's own systems rather than only answering questions, and it charges per resolved outcome rather than per seat. Headquartered in San Francisco and privately held at a multi-billion dollar valuation, it works with retailers, telecommunications operators, financial services firms and healthcare providers.

Products
Agent Evaluation
Tooling that scores agent behaviour against defined expectations before and after deployment. Without it there is no way to change a production agent with any confidence about the effect, which is the main reason enterprises hesitate to hand over customer conversations.
sierra.ai
Voice Agents
Telephone agents handling spoken customer interactions with low enough latency to feel natural. Voice is where most customer service volume still sits, and it is considerably harder to get right than chat.
sierra.ai
Agent OS
The development environment in which agents are configured, tested and monitored. It is what lets a customer's own team adjust behaviour without going back to the vendor for every change, which is the difference between a product and a consulting engagement.
sierra.ai
AI Agents
Conversational agents that resolve customer service issues by taking action in the company's own systems. Charging per resolved outcome rather than per seat aligns the vendor's revenue with whether the agent actually works.
