What sproof does
sproof GmbH is an Austrian SaaS company founded in autumn 2019 by Dr. Clemens Brunner, Dr. Fabian Knirsch, and Erich Höpoldseder, headquartered in Puch bei Hallein (Salzburg) with a secondary office in Vienna. The company operates a modular cloud-based platform for eIDAS-compliant digital signatures (sproof Sign) and identity verification (sproof Ident), supplemented by an eID Hub integrating over 90 European identity providers, an embeddable Widget, a high-volume Fastlane module for SEPA mandates, and a Validate API for signature integrity checking. All data is processed and stored in ISO 27001-certified European data centers, providing full GDPR and Schrems II compliance with no US Cloud Act exposure.
The platform is 100% developed and hosted in Europe and holds ISO 27001, GDPR, FDA 21 CFR Part 11, EU MDR, HIPAA-referenced, and DORA compliance certifications. It is eIDAS 2.0 and EUDI-Wallet ready, and has received the IÖB award for public sector use. The technology stack is API-first, with documented integrations into SAP, Salesforce, Microsoft Dynamics, and DMS/ECM systems; an 'Agent-ready' REST API was launched in March 2026 to enable AI-agent orchestration of signature workflows.
sproof employs a hybrid go-to-market combining product-led growth (a freemium private tier plus a 2-week business trial) with a direct enterprise sales motion and a partner/reseller channel including Kyocera and DATEV. Revenue is generated primarily through annual SaaS subscriptions across Single, Team, and Enterprise tiers, with usage-based overages and multi-year enterprise contracts available; pricing is not publicly disclosed. The customer base spans regulated industries (energy, banking, payment services, healthcare/telemedicine, education, government, and manufacturing) primarily across the DACH region with broader European expansion signaled by 23+ language localizations. Total disclosed funding is approximately $3.2M raised in September 2023, supplemented by earlier support from the European Super Angels Club and Linde Verlag, with no identified venture capital or institutional backers.

sproof competitors and assessment
Company assessmentBroad incumbents
- IDnow: European identity verification platform offering KYC, eIDAS QES, and EUDI-Wallet-ready services. Comparable on the identity verification and qualified signature dimensions of sproof's offering.
- Adobe Acrobat Sign: Adobe's enterprise e-signature offering bundled within Document Cloud. Competes for the same enterprise signing workflows; broader document management suite provides cross-sell advantage but Adobe is also a US-based vendor subject to the same sovereignty concerns sproof addresses.
- DocuSign: Global e-signature and agreement cloud market leader. Directly comparable in core e-signature functionality and enterprise target market; sproof explicitly positions itself as a European alternative to DocuSign.
Emerging players
- DocuWare: German DMS/ECM vendor with embedded e-signature capabilities. Overlaps with sproof in document workflow and enterprise customers; partnership/integration opportunity rather than direct head-to-head.
- Verimi: German identity platform providing login, eID, and qualified signature services. Overlaps with sproof's sproof Ident and eID Hub modules in European digital identity use cases.
Direct peers
- Yousign: French eIDAS-compliant e-signature SaaS serving European SMBs and enterprises. Most direct European head-to-head competitor with comparable regulatory positioning and target customer profile.
- SignNow (airSlate): E-signature platform from airSlate offering electronic signatures with workflow automation. Comparable product scope and SMB/enterprise target market.
- HelloSign / Dropbox Sign: E-signature SaaS originally independent, now owned by Dropbox. Competes for SMB and mid-market signing workflows globally; a direct functional competitor though US-based.
- Skribble: Swiss-headquartered e-signature platform with eIDAS-qualified electronic signature support. Closely comparable on regulatory positioning (Swiss/EU data sovereignty) and SMB-to-enterprise target market.
Others
- Authentik (formerly IDnomic / Atos): Thales digital identity and trust services arm providing e-signature, PKI, and identity infrastructure to enterprises and governments across Europe. Comparable in serving regulated enterprise identity/signing use cases though with broader portfolio.
