SignNow (stylized as signNow, also marketed as airSlate SignNow) is a cloud-based electronic signature service that allows users to sign, send, and manage documents from a web browser or mobile device. The service was founded in 2011,[1] acquired by Barracuda Networks in 2013,[2] and sold in 2017 to the document management company PDFfiller,[3][4] which was renamed airSlate in 2019.[5]
History
[edit]Founding and early years (2011–2013)
[edit]SignNow was founded in 2011 in Newport Beach, California, by Chris Hawkins, who had previously operated NotaryNow, a service connecting users with notaries by webcam.[1][6] In March 2011, the company raised $500,000 from angel investors ahead of the product’s launch the following month.[1] In March 2012 it raised $2 million in a round led by Khosla Ventures and released a free iPad application alongside its existing iPhone and Android apps; at the time it competed with DocuSign and EchoSign, later renamed Adobe Sign.[7][8]
Barracuda Networks (2013–2017)
[edit]Barracuda Networks acquired SignNow in a transaction announced on 22 May 2013. Barracuda stated the service had more than one million users and over 100,000 small-business customers at that point.[2] In March 2015 Barracuda renamed the product CudaSign, priced it at $1 per user per month and placed it within its data protection line, reporting more than two million users.[9][10]
In October 2017, as part of a strategy of divesting non-core products, Barracuda sold SignNow for $8.6 million to PDFfiller, and the product regained its original name.[3][4]
airSlate era (2017–present)
[edit]PDFfiller, a document management company with headquarters in Boston and its main development office in Kyiv, rebranded as airSlate in 2019 after raising approximately $30 million from General Catalyst and Horizon Capital.[5]
In January 2021, airSlate raised $40 million from investors including Morgan Stanley Expansion Capital, General Catalyst, and HighSage Ventures, bringing its total funding to $80 million.[11]
In June 2022, the company raised a further $51.5 million in a round led by G Squared with participation from UiPath Ventures, at a valuation above $1 billion; TechCrunch reported that about 80 percent of the company's workforce was based in Kyiv, Ukraine.[12] In July 2022, airSlate acquired DocHub, an online PDF editing and e-signing platform distributed through the Google Workspace Marketplace.[13][4]
In July 2025, airSlate co-founder Vadim Yasinovsky returned as president and CEO, succeeding long-time chief executive Borya Shakhnovich, who had held the role for 13 years.[14][15]
Features
[edit]SignNow is a subscription service used through a web browser, with applications for iOS and Android. Users upload a document, place fields such as text boxes, radio buttons and drop-down menus, assign each field to a particular recipient, and route the document to one or more signers; completed documents are recorded with an audit trail.[16] Documents can be saved as reusable templates, and higher subscription tiers add bulk sending, a kiosk mode for collecting signatures in person on a mobile device, and the option to request payment at the moment of signing. Signer identity can be confirmed with two-factor authentication.[16]
The service connects to cloud storage and business applications including Google Drive, OneDrive, Box, Dropbox, Microsoft 365, Salesforce and NetSuite, and provides a REST API and a Zapier connector.[16]
At the time of TechRadar's 2025 review, plans ranged from $8 per user per month billed annually to $50 per user per month for the highest tier, which carried HIPAA and 21 CFR Part 11 compliance.[17] TechRadar reported in 2026 that paid plans allow unlimited users and are billed by the number of documents sent for signature, with additional fees beyond 100 signature invitations a year.[18][17]
Reception
[edit]Reviewing the service for TechRadar in 2025, Steve Paris rated the signature-creation workflow 4.5 out of 5 and pricing and document preparation 4 out of 5, describing document setup as intuitive but noting the absence of text-formatting options and concluding that the service suited collaborative teams better than individual users.[17] TechRadar's 2026 roundup of e-signature software placed SignNow first, as its pick for business use, citing the unlimited-user policy on paid plans.[19] Tom's Guide named it the best e-signature software for multiple signers.[20] Galen Low of The Digital Project Manager rated the service 4.6 out of 5 in 2026.
