Detailed Review
sproof GmbH is registered in Puch bei Hallein near Salzburg under FN 520262t at the Landesgericht Salzburg, and its imprint names no parent company — in a category where half the familiar names now sit under a holding somewhere else, an Austrian company that still belongs to itself is worth noting.
The pricing model is the unusual part. Instead of selling seats and metering nothing, sproof sells allowances: Single at €15 a month covers one user with 100 advanced and 10 qualified signatures a year, Team at €170 a month covers ten users with 1,200 advanced and 120 qualified, both billed annually and excluding VAT, with Enterprise quoted.
There is a genuinely free plan for private use, students and associations, and a fourteen-day trial of the paid plans. A low-volume team knows its bill for the year in advance; a busy one has to check whether 100 signatures is anywhere near enough.
Two things are missing and both matter here. sproof describes its hosting as ISO 27001-certified data centres in Europe and names neither the country nor the provider, which for a tool sold on European data handling is the one sentence a buyer wants completed.
And sproof is not on the Austrian trusted list: qualified signing runs through the eID providers integrated into its eID hub, not through sproof itself. It does not publish a founding year either. SES, AES and QES are all covered, and there is a REST API.
