Fillo

Provides headless form infrastructure that handles schema, validation, conditional logic, file uploads, response storage, version history, exports and delivery so teams do not build custom validation services, upload pipelines and webhook systems for each form. Serves developers and product teams in B2B companies building onboarding, intake, support and approval flows inside existing products. Delivered as SaaS with React and DOM SDKs that render native controls in the host app and a hosted editor or code-based schema, hosted in the EU.
