Overview

BoldSign is an electronic signature platform launched in 2021 by Syncfusion, a developer tools company founded in 2001 and headquartered in Research Triangle Park, North Carolina. BoldSign was designed from the ground up to be embeddable into other software products through SDKs and a REST API, while also functioning as a standalone e-signature web app.

The platform targets both end-user businesses that need to send and sign contracts, and software teams that want to build native document-signing workflows into their own applications without routing users to a separate signing service.

Key Features

BoldSign supports reusable templates, bulk sending, bulk signature links, custom branding, and document categorization for tracking sent and received envelopes. Every signature event is captured in a complete audit trail, and completed documents are digitally signed to prevent tampering.

Higher tiers add single sign-on (SSO), custom user roles, HIPAA compliance, AI-powered document capabilities, and Salesforce integration. BoldSign complies with the U.S. ESIGN Act, eIDAS, SOC 2, GDPR, HIPAA, and PCI DSS, making it viable for regulated industries.

Pricing

BoldSign's web app has four tiers: Essential (free, 25 envelopes/month), Growth ($5/user/month annual), Business ($15/user/month annual, unlimited envelopes, SSO, HIPAA), and Premium ($99/month annual, unlimited senders). Monthly billing is available at a higher per-month rate on paid tiers.

Developers integrating signing directly into their own product can instead use the Enterprise API, billed at $0.75 per envelope with a $30/month minimum covering 40 envelopes.
