Diapason and Digital Vault Services (DVS) jointly digitalize guarantee management across Europe

Paris / Munich, May 7, 2026 – Diapason, a European leader in Treasury Value Management, and Digital Vault Services GmbH (DVS), provider of the pan-European multiguarantor Guarantee Vault Platform (GVP), announce their technical integration via a secure API. This partnership connects myDiapason Guarantees with DVS’s neutral and interoperable market infrastructure, enabling corporates to manage guarantees fully digitally – from internal request to release across the entire lifecycle – while making them accessible to all involved parties through a shared Single Source of Truth.

Despite their significant financial weight, guarantees remain one of the most manual processes in corporate treasury today: exchanges via email and PDFs, lack of interoperability between corporates and banks, fragmented lifecycle tracking, increasing operational complexity, and exposure to error risks. This gap is particularly evident for international groups managing multiple formats and jurisdictions without a unified system.

Thanks to the integration of myDiapason Guarantees with the Guarantee Vault Platform, corporates now benefit from a fully digital end-to-end process, from internal request to release. Approval, amendment, and tracking workflows are managed within myDiapason Guarantees. Issuance and amendment requests are automatically transmitted to banks and insurers connected to GVP, including Deutsche Bank, Crédit Agricole, Allianz Trade and several other connected Banks and Insurers, enabling multi-guarantor issuance without re-entry of data.
Once a guarantee is issued and signed, data is synchronized in real time with myDiapason for continuous lifecycle monitoring. Corporates leverage the API integration and continue to operate within their treasury environment within Diapason, while the shared Single Source of Truth is maintained within Guarantee Vault and accessible in real time to all authorized parties, including guarantors and beneficiaries. This enables transparent, secure collaboration across all parties based on a single, trusted data foundation.

The integration reflects a broader move toward multi-channel connectivity across treasury systems, platforms and corporate environments, reinforcing the role of shared infrastructure in enabling digital guarantees at scale.

This partnership brings together two players deeply rooted in the European financial ecosystem. Founded in 2018 with the support of 16 industry participants, DVS continues to expand its pan-European infrastructure network to France, Spain, and the Nordics, with this integration contributing to the further development of its presence in the French market. Diapason, myDiapason Guarantees platform is used in over 50 countries, shares the same vision of a sovereign and sustainable infrastructure serving European finance teams.

Together, they are building a local, integrated, and sustainable alternative to fragmented or non-European solutions, supporting treasurers managing complex guarantee portfolios and enabling interoperable guarantee processing across domestic and cross-border trade corridors.

“Digital guarantees require a shared and neutral market infrastructure. By connecting the Guarantee Vault Platform to myDiapason Guarantees, we provide French and European corporates with direct access to our pan-European guarantor network in a secure and interoperable environment. This is precisely the kind of standardization the market needs,” said Ludger Janßen, Co-CEO of Digital Vault Services.

“For 35 years, Diapason has built strong European expertise in corporate treasury. This partnership with DVS reflects our ambition to go further: making myDiapason Guarantees not only the most comprehensive solution on the market for managing guarantees, but also the gateway to the European digital guarantee infrastructure. This represents a new dimension of Treasury Value Management, transforming a costly administrative process into a real and measurable financial performance lever,” added Raphaël de Talhouët, President of Diapason.

This partnership directly addresses the challenges faced by finance teams managing significant guarantee portfolios:

• Elimination of manual exchanges and data re-entry
• Reduction of operational risks and limit breaches
• Compliance with IFRS reporting requirements for off-balance sheet commitments
• Unified multi-guarantor issuance with Banks and Credit Insurers, covering domestic and international guarantees
• Real-time visibility across all guarantee commitments with collaboration based on a shared, real-time Single Source of Truth
• End-to-end digital lifecycle management of guarantees, from application to release
• Connection of all stakeholders within a single workflow: applicants, banks, insurers, and beneficiaries

This partnership reflects a shared ambition: to firmly embed digital guarantees at the heart of financial practices and accelerate their standardization across Europe through a neutral and interoperable shared infrastructure connecting corporates, banks, insurers, and beneficiaries.
