About Partisia

The company

Partisia is a privately owned company registered in Denmark. The ownership of the company is shared by Alexandra Instituttet A/S and Partisia Holding ApS. The ownership combines internationally renowned researchers and experts in advanced cryptography, business economics and software development as well as experiences in taking research ideas to the market. The combination of competences makes Partisia able to timely deliver solutions that are rock solid as well as highly innovative.

As pioneer, Partisia has sold commercial-grade MPC software solutions since 2008. Initially the company focused on secure auctions for commodities like production contracts, energy-related products and high-stake auctions used for selling spectrum licenses. In parallel the company has developed infrastructure for managing encryption keys in the cloud and other critical infrastructure for secure computation. As part of the commercialisation strategy, selected businesses have been moved and matured in separate spinouts together with investors and other business partners such as:


The name

Our brand “PARTISIA” is a contraction of the three Latin words:

PARTIo (a verb), translated to English as: part, distribute, etc.

fiduS (a verb), translated to English as: trusty, trustworthy, etc.

fiducIA (a noun), translated to English as: trust, confidence, etc.

To us, Partisia means “Distributed Trust” a common expression in the related literature. Although it may seem surprising that distributed trust can be more trustworthy, this is in fact the case. Read more about the technology >>

The starting point

Partisia is a commercial spin-off from internationally ground-breaking research projects

Partisia was established in 2008 as a commercial spin-off from two research projects: Secure Computation, Economy and Trust starting in 2004 and Secure Information Management and Processing (SIMAP) starting in 2006. Both projects were funded by the Danish Council for Strategic Research.

Theoreticals Ideals Meets Practical Implementation

The tools provided by secure multiparty computation provide perfect ways to implement basic economic ideals.

The economic perspective: The so-called revelation principle has become a cornerstone in economics. The principle states that it is at least as good as any economic mechanism to rely on direct revelation where the parties involved tell the truth to an impartial mediator or social planner that use the revealed information in the best interest of the parties. Implementing such a planner in a secure and trustworthy way has always been a challenge.

The cryptographic perspective: In theoretic cryptography the research topic secure multiparty computation (MPC) has for many years been motivated by reference to practical problems where a so-called trusted third party is required. This is because MPC exactly realizes a trusted third party in a provably secure way. So, while the trusted social planner has been a common construct in economics for decades, the modelling of such an ideal trusted social planner has likewise been a challenge in computer science for decades. Via a dedicated focus on applications, the research projects mentioned above have resulted in the first large-scale application of secure multiparty computation.

The vision and strategy

Our aim is to set a new standard for privacy enhancing software solutions


To set a new standard for secure software solutions based on confidential information from multiple participants across all platforms from cloud computing to blockchains.


To focus on our innovating software to addresses cloud security and confidentiality in collaborative solutions.

To develop software solutions in close collaboration with partners with the detailed knowledge of the individual businesses.

To collaborate with business partners and investors in achieving our goals.
