Control, compliance and digital signing in one platform

Addo Sign is not just a tool for digital signing. It is a Nordic digital communication platform that combines identification, data collection, signing, and distribution in one unified flow.

Many competing solutions focus primarily on the signature itself. Addo Sign focuses on the entire process before, during, and after signing – with particular emphasis on compliance, workflow control, and Nordic requirements.

The key difference between Addo Sign and Penneo is the level of flexibility. Penneo is strongly rooted in the audit industry and built for fixed use cases, whereas Addo Sign is developed as a modern, modular platform where organisations can continuously adapt workflows – with greater control and lower costs for setup and changes.

International solutions are typically built for a global market and often require local adaptation to work optimally in a Nordic context.

Addo Sign, on the other hand, is built for the Nordics from the outset and supports national standards and workflows, including:

• national eID solutions such as MitID and BankID
• digital mail solutions such as e-Boks, mit.dk and Kivra
• Nordic workflows and administrative requirements
• hosting and data processing within the EU

This makes Addo Sign particularly well suited for organisations with high demands for compliance, data sovereignty, and proper digital identification – without the need for additional customisation or third-party solutions.

Yes. Addo Sign is built for both small businesses and large organisations – without being divided into separate products.

Small businesses can get started simply and quickly. As requirements grow, the platform can be expanded with advanced workflows, automation, self-service, and integrations, enabling Addo Sign to support complex processes, compliance requirements, and cross-organisational needs – without switching solutions.

Yes. Addo Sign is already used in regulated environments and the public sector. More than 50 municipalities in the Nordics use Addo Sign.

The solution supports eIDAS, national eID solutions, digital post, as well as documentation and traceability. At the same time, the platform is designed for low organisational friction, which is crucial in larger organisations.

No. Addo Sign includes an unlimited number of users by default.

This means organisations can roll out the solution across departments without additional licence costs and without friction during growth or organisational changes.

Pure signing tools such as Adobe PDF and Microsoft Word primarily focus on the signature itself. Addo Sign focuses on the workflow, automation, distribution, and security.

Addo Sign supports data collection, identification, signing, distribution, and documentation in one coherent flow, reducing errors, manual corrections, and compliance risks.

Yes. Addo Sign includes Addo Form, which makes it possible to collect structured and validated data before signing.

Digital forms can include conditional questions and be combined directly with signing in the same flow. This is used, among other areas, in HR, the public sector, and sales and contract processes.

Addo Sign is hosted exclusively within the EU.

This means data remains under European jurisdiction and that the solution is not dependent on US cloud services. This provides a strong foundation for GDPR and compliance.

Addo Sign is particularly relevant for organisations that need more than just digital signing.

The solution is well suited for companies and public organisations that work with compliance, require flexible workflows, want to avoid vendor lock-in, and operate in a Nordic or European context.

Some European organisations use non-European signing solutions such as DocuSign, Adobe Acrobat Sign, and Dropbox Sign. However, this can create challenges related to data sovereignty and compliance with European requirements.

Although several of these solutions use EU data centres, they remain subject to US legislation, including the CLOUD Act. This can create uncertainty around data access, legal control, and documentation in relation to GDPR, eIDAS, and national regulations.

For many Danish companies – especially larger organisations and public sector entities – it is therefore crucial to choose a solution where data security, compliance, and European legislation are built in from the outset and do not depend on legal add-ons or separate agreements.
