Digital platform for managing guarantees

Trustlog GmbH

‘Guarantees are an integral part of commercial and public construction projects. However, the administrative processes that they entail are still very manual and therefore time-consuming and often prone to errors. It took several days for guarantees to reach the recipient. Our system has the answer: it provides a smart, digital and secure solution for creating and managing digital guarantees. With the support of adesso’s IT experts, we are setting a new market standard for all those involved in the guarantee process.’

Jonathan Szejnmann, Managing Director of Trustlog GmbH



The construction industry requires fast and flexible financing leeway. Medium-sized and large construction projects in particular are usually multi-million undertakings involving several stakeholders. Employers of the construction project therefore require guarantees as security to ensure that both their subcontractors carry out the project successfully, and that there is a guarantee that the work will last beyond the completion of the project. In the construction industry, therefore, the motto is ‘time is money’.

The old paper-based processes brought with them numerous disadvantages: system disruptions, time-consuming mailing, lengthy process times per guarantee, complicated individual content checks, different filing structures. In summary, the paper guarantee caused problems for all parties involved. For that reason, insurance providers R+V and VHV decided to develop a digital solution that makes the issuing, management and safekeeping of guarantees a user-friendly, secure and fast process for both the client of the construction project and the guarantor and contractor.

Trustlog developed the new independent and digital guarantee platform Trustlog for the smart management of guarantees together with the experts from adesso. Thanks to excellent collaboration and agile methods that featured an MVP approach and numerous user tests, the project went from kick-off to pilot launch in just six months. A modern technology stack acted as an enabler for the platform.
