What it is

What It Does

airSlate SignNow is a general-purpose electronic-signature and document-workflow tool, now part of workflow-automation company airSlate. It handles e-signing, signing-order routing, and document templates, and integrates with Salesforce, NetSuite, Google Workspace, Box, Dropbox, OneDrive, and others. It is not legal-specific but is used by law firms alongside other industries for routine signing.

What We Found

SignNow was founded in 2011 by Chris Hawkins and Andrew Ellis, acquired by Barracuda Networks in 2013, then sold to pdfFiller (now airSlate) in 2017. It is headquartered in Brookline, Massachusetts, the same base as parent airSlate (501-1,000 employees). The vendor cites over 20 million users. The LinkedIn page “airSlate SignNow” (handle signnow-esignature) shows roughly 4,991 followers (June 2026); the previously recorded count of 40 was stale and has been corrected.

What We Haven’t Verified

  • The “20 million+ users” figure — vendor-stated, not independently audited
  • Several listed integrations (Acumatica, LendSaaS) are marked vendor-claimed in source data
  • This page was assembled from publicly available information, not hands-on testing or practitioner feedback.
