Sierra (Bret Taylor)
Outcome-priced customer-experience AI agents
Sierra, co-founded by OpenAI chairman Bret Taylor, builds customer-service AI agents priced on resolved outcomes and reached a reported ~$10B valuation in 2025. It is a leading example of the shift to agentic, outcome-based enterprise AI. Its governance ties (Taylor chairs OpenAI) illustrate the tight interlock between labs and the application layer.
