Outcome-priced customer agents that own the whole resolution

Sierra builds customer-facing agents across chat, voice and email that connect to CRMs, order systems and data warehouses and complete actions rather than just answer questions. Pricing is outcome-based and negotiated per resolved conversation, so the interesting metric is cost per resolution instead of cost per token.
