Dropbox Sign
What it is
What It Does
Dropbox Sign (formerly HelloSign) is an electronic signature service for sending, signing and managing legally binding documents. It carries a tamper-evident audit trail on each signature request and offers an eSignature API for embedding signing into other applications. Signatures are legally binding under the US ESIGN Act. It is a product of Dropbox, which acquired HelloSign in 2019.
What We Found
HelloSign was founded in 2011 (originally as HelloFax) and acquired by Dropbox for $230M in 2019, then rebranded to Dropbox Sign. The service integrates with Dropbox, Salesforce, Slack, Microsoft Word, OneDrive, Outlook, Google Docs/Drive/Calendar (integration list verified on the vendor’s integrations page). It is general-purpose document signing rather than a legal-specific product, though it is widely used for legal documents.
What We Haven’t Verified
- Current pricing tiers.
- This is a horizontal e-signature tool, not legal-tech-specific.
- Feature claims and workflow mappings are based on what the vendor and third-party listings publish — not hands-on testing or practitioner feedback.
