Sierra
Bret Taylor's customer-service agents — outcomes-priced AI labor.
You're looking at an AI product record: something people actually use — and the company and models behind it.
Sierra deploys branded support agents that actually resolve tickets, priced per outcome rather than per seat — the template for 'agents as labor' economics, from the OpenAI chairman's own startup (valued ~$10B in 2025).
