SSI-based digital passport to facilitate data portability in the housing rental sector

Team: Katrie Lowe, Pavel Metelitsyn, Stefanie Behrendt, Juan Caballero

Domi is a digital rental passport and contract management platform that seeks to address the issue of data portability and privacy in the housing rental process.

Data ownership, portability and privacy are significant issues in the housing rental sector, which, particularly in Europe, is an important means for securing housing for many citizens. The process of securing housing involves the exchange of significant amounts of sensitive personal data that constitutes one’s “rental identity”, and much of the friction faced by both tenants and property managers is derived from the way data has traditionally been managed through the rental lifecycle.

Domi leverages the new generation of Self-Sovereign Identity (SSI) based digital identity technology being developed by the European Union through the EBSI/ESSIF project for the rollout of government-backed SSI credential ecosystems in Europe. Using SSI-technology, Domi enables tenants to translate their verified rental data into a highly portable and privacy-preserving “passport” for building trust with landlords globally. On the other side of the equation, landlords benefit from a streamlined, truly GDPR-compliant means of managing their rental contracts. The aim is to establish a universal, simple and privacy preserving way for landlords and tenants to exchange verified rental data in both the rental application process, and in the contract management process.

Planned outcomes of the NGI DAPSI project include further exploration of the application potential of Self-Sovereign Identity technology in the real estate sector, and the development and launch of a private-beta version of the Domi rental passport.

Achievements from the first phase of the DAPSI programme

Domi’s achievements and key results as part of the first phase of DAPSI include the roll out of a user research strategy (survey campaigns and user research interviews), development and freeze of our product technical requirements and technical experimentation to support the drafting of our architectural requirements.


Our participation in DAPSI’s first phase was significantly beneficial for Domi’s progress. In addition to the funding, which gave us the resources to grow our team and push forward our technical development, the business coaching was extremely helpful in unblocking many fundamental uncertainties we faced in trying to move forward as an early-stage startup and develop meaningful practical strategies to move forward with confidence. Part of this was also down to being surrounded by such an amazingly supportive cohort – drawing learnings from group sessions where other teams would share their own company reflections navigating homework exercises and business challenges and from mutual candid feedback.
