Sierra is the leading platform for customer-facing AI agents, working with many of the world's biggest brands — including The GAP, Rocket Mortgage, SoFi, Sutter Health, and SoftBank — to transform how they serve customers and grow their businesses. These are the kinds of projects that strategists on our team have worked on recently: Launch an order management agent for a national apparel brand — order lookup, cancellations, returns, and exchanges — then hill-climb containment and CSAT week over week.
