Sierra

Sierra is an AI customer service startup with an Agent OS that allows enterprises to design, deploy, and govern agents that resolve high-stakes customer workflows across voice and digital surfaces, integrated to systems of record for refunds, plan changes, and account updates. The commercial model pays only on successful resolution, aligning spend with realized savings and making expansion straightforward when automation rates improve. The platform’s emphasis on auditability and policy control targets the governance requirements that now determine vendor selection. As enterprises replace labor-driven support with governed, outcome-linked automation, Sierra’s Agent OS can serve as the operating layer for resolution across voice and digital channels.
