What Ondertekenen does
Ondertekenen, operating under the Signhost brand and legally constituted as Entrust B.V. (formerly Evidos), is a Netherlands-based cloud digital signature platform founded in 2013 and headquartered in Haarlem. The company provides legally compliant electronic signature services under the eIDAS regulation and Dutch Civil Code article 3:15a, supporting simple, advanced, and qualified signature levels. Its technology stack includes PKI infrastructure with hardware security modules, PAdES and XAdES format support, timestamping with transaction receipts, and a multi-method identity verification layer integrating iDIN, iDEAL, DigiD, eHerkenning, SMS, passport checks, and the proprietary ID Proof service for global identity verification with liveness control scanning.
The platform is distributed through three primary go-to-market motions: a product-led self-serve channel with a free Go package, an API-first developer channel enabling deep embedding into customer systems, and an enterprise field sales motion targeting regulated sectors. Over 3,000 organizations use the platform, spanning financial services (ABN AMRO, ING, BNP Paribas Personal Finance), housing corporations (Vesteda, Stadlander, Het Wonen), government (Gemeente Ermelo), healthcare (Richting), HR and staffing (Please Payroll, Talent & Pro), childcare (Flexkids), insurance (TAF), education (Hogeschool Utrecht), energy (Essent, TotalEnergies), and retail (Ahold Delhaize). Vertical SaaS partnerships with Flexkids and Corpoflow embed signing into domain-specific software platforms, creating an indirect distribution layer.
Revenue is generated through a combination of subscription tiers (Go free, Plus, Basis), credit-based transaction pricing, and custom enterprise API contracts. The company reported no external funding rounds and appears founder/management-owned under Director Kick Willemse. In 2024, the Ondertekenen.nl brand was consolidated into Signhost, signaling a transition toward positioning as an international platform rather than a Dutch-only service, supported by multi-language customer support in Dutch, English, Spanish, and German.

Ondertekenen competitors and assessment
Company assessmentDirect peers
- Adobe Acrobat Sign (Adobe Sign): Adobe's enterprise-grade e-signature solution bundled with the Acrobat document ecosystem. Comparable to Signhost on advanced/qualified e-signature capability, eIDAS compliance, and large enterprise customer base. Competes head-on in regulated European verticals (financial services, government).
- ValidSign (Visma): Dutch-headquartered e-signature provider, now part of the Visma group. Closest direct comparator within the Netherlands market alongside Signhost; comparable pricing tiers, similar vertical coverage and SMB focus. Direct competitor for Dutch HR, accountancy, and SMB contracts.
- DocuSign: The global market-leading electronic signature platform with broad enterprise coverage. Directly comparable to Signhost because both deliver cloud-based, legally compliant e-signature workflows to enterprise and SMB customers, with comparable feature sets (audit trails, multi-method verification, API integrations). DocuSign's scale is the primary competitive benchmark for Ondertekenen.
- Zoho Sign: E-signature module within the Zoho productivity suite, offering free tier and integrations to other Zoho apps. Comparable to Signhost on credit-based pricing, API integration model, and SMB upmarket motion, with similar regulatory and EU-compliance positioning.
- Dropbox Sign (HelloSign): Cloud-based e-signature product (formerly HelloSign) now part of Dropbox. Comparable to Signhost on self-serve/SMB-friendly UX, API-first developer model, and broad customer adoption among technology-forward organisations, though it is less focused on qualified signatures under eIDAS.
- Connective: Belgian digital signature specialist focused on enterprise and financial services customers in Benelux. Directly comparable to Signhost on geographic focus, eIDAS-qualified signatures, and emphasis on API-first integration into banking and insurance workflows in the Netherlands/Belgium region.

Broad incumbents
- OneSpan: Global identity and digital agreement vendor combining e-signature with strong authentication, mobile security, and fraud prevention. Comparable to Signhost where Ondertekenen intersects with identity verification (ID Proof) and qualified e-signature for regulated industries, though OneSpan operates a much broader security portfolio.
- Namirial: European trust services provider offering eIDAS-compliant e-signature, digital identity, and certified email across multiple countries. Comparable to Signhost on qualified signature compliance and EU regulatory breadth; larger group with cross-country trust service provider status.
Emerging players
- Evrotrust: Bulgarian/European qualified e-signature and digital identity provider focused on eIDAS and eIDAS 2.0 (EUDI Wallet) interoperability. Comparable to Signhost's identity verification + signing stack, though earlier-stage with a regional rather than Netherlands-anchored customer base.
