Dropbox Sign (formerly HelloSign) vs. Assembly

Dropbox Sign (formerly HelloSign) helps teams send, sign, and manage agreements where their work already lives. Most teams introduce unnecessary friction the moment a document needs a signature—separate systems, extra handoffs, and chasing approvals across disconnected workflows. Dropbox Sign keeps the process connected, moving from draft to signed with fewer steps.

Assembly is the AI-powered platform for professional service firms, from accounting and bookkeeping practices to agencies and consultants. It combines a branded client portal, a simple CRM, and an AI app builder that lets your firm add any software it needs without a dev team. Clients get one branded place for messages, files, forms, tasks, contracts and e-signatures, and invoices they can pay online. Your team runs on a CRM with automated reminders and an AI Assistant that knows full client context. When your firm needs something the portal doesn’t do yet, describe it.
