Vellum (www.vellumhub.app) is a Software as a Service (SaaS) platform that serves as a branded client portal overlay for freelancers, agencies, logistic companies and law firms... Instead of replacing the software you already use, Vellum acts as a unified digital storefront. It aggregates live data from popular tools like Google Drive, Dropbox, Slack, WhatsApp, Stripe, and PayPal into a single, cohesive hub for your clients. The most notable technical differentiator is its zero-storage architecture: Vellum never hosts or stores your underlying files, invoice data, or messages. It simply verifies the client's access token and relays live previews directly from your third-party providers. In addition to its core client hubs, Vellum has expanded into automated document generation with a live, free invoice playground and a dedicated template ecosystem.
