About Feathery Feathery is the AI operating system for financial institutions. With hundreds of clients and over $30 million raised, Feathery is the fast-growing leader in financial agentic automation. Industry leaders like Tokio Marine, Sequoia Financial, and Cerity Partners run their client-facing workflows on Feathery, from onboarding and risk assessment to reconciling systems and generating proposals and reports. At the center of it all is Robin, our AI operations assistant. Robin scans client documents, configures and deploys workflows, assists users in their day-to-day work, takes notes during meetings, and supports a growing range of operational tasks across the client lifecycle.
