Overview
Nitro is a PDF and e-signature vendor that its about page says was founded more than two decades ago in Melbourne, Australia; it now lists offices in San Francisco, Dublin, Toronto, Antwerp, Porto and Melbourne and states that it serves more than 67% of the Fortune 500[7]. Nitro Software Limited was listed on the ASX until a contested takeover in 2022–2023, in which Potentia Capital’s bid competed with a scheme from KKR-backed Alludo[8]. Potentia and HarbourVest completed the acquisition of the remaining 80.2% stake on 31 March 2023 at A$2.20 per share, with compulsory acquisition of the remainder beginning the same day[9].
The PDF line is sold as Nitro PDF Standard (per user per month, billed annually), Nitro PDF Plus for large organisations, which adds single sign-on, domain control, Azure Information Protection and Nitro Analytics, and Nitro PDF Classic, a Windows-only licence paid once for a three-year term. Separate Nitro Sign plans cover e-signature, including advanced and qualified signatures under eIDAS and ZertES on the Enterprise tier[6].
Nitro is designed for company-wide rollouts with an admin portal and usage analytics. Its main drawback for comparison is that the pricing page shows no numeric prices; rates appear at checkout or through sales, and online purchases are capped at 20 licences[6].
