When another tool is the better pick
Said plainly, from the comparison pages. If one of these is you, Signifier is not the right tool yet.
You run Microsoft 365, or both
BulkSignature, Exclaimer, WiseStamp and SyncSignature all cover Microsoft 365. Signifier is Google Workspace only for now.
Procurement needs SOC 2 or ISO 27001 today
Exclaimer holds both. Signifier does not hold either yet; its security page says what it does instead. Security
You need SSO for the admin console
WiseStamp has it on its Platform tier. Signifier admins sign in with Google.
You need HRIS, Salesforce or HubSpot data
Exclaimer Pro connects to them. Signifier reads the Google Workspace directory only.
