Sealio turns any document into a signed, legally binding record — in the time it takes to open your inbox. Built for solo founders, and built to survive an enterprise security review.
No app to install, no account required for signers. Just a document that gets done.
Upload a PDF or Word doc, or start from a saved template. Sealio keeps the formatting exactly as it was.
Drag signature, initial, and date fields to where they belong, add your signers, and send — one click, done.
Every signature is time-stamped, encrypted, and written into a tamper-proof audit trail the moment it lands.
Upload, tag fields, send. Average time to first signature: 4 minutes.
Every view, click, and signature is timestamped, hashed, and locked to the record.
Save any document once — signers just fill it in seconds next time.
Send the same contract to 500 people without opening 500 tabs.
Native integrations with Salesforce, Google Drive, and Slack.
Full mobile signing on any device, no app download required.
Every document carries the paper trail to prove it — who signed, when, and from where.
Documents are encrypted in transit and at rest, with keys rotated on a strict schedule.
Every signed document ships with a full chain of custody — IP, timestamp, and device.
Role-based permissions, single sign-on, and centralized user management for teams.
