OneSchema

OneSchema is a San Francisco data-integration company that turns the messy, unglamorous problem of importing spreadsheets into a solved one. Its embeddable CSV importer lets software teams ship a polished, validated file-import experience in about a day instead of building and maintaining fragile parsing scripts for months. Around that core, OneSchema has grown into a broader platform - recurring file feeds and, more recently, AI agents that autonomously intake, clean, and reconcile legacy data - aiming to be the default layer for the 'long-tail' data that never quite fits an API.
