Lissi GmbH, a Wiesbaden-based digital identity infrastructure startup, has raised €3.5 million in a new funding round led by Ventech, with participation from BM H Beteiligungs-Managementgesellschaft Hessen and existing backers main incubator, part of Commerzbank Group, and Ninepointfive Ventures.

The company develops infrastructure that helps financial institutions integrate European Digital Identity Wallets into processes such as KYC, strong customer authentication, and digital credential issuance. Its flagship product, the EUDI Wallet Connector Suite, is designed for regulated environments and can be deployed on premises or in private cloud setups.

Lissi said the new capital will be used to expand its wallet infrastructure offering for the financial sector, including further development of its EUDI Wallet Connector Suite and a new SDK that would let banks embed ID wallet functionality directly into their apps. The company is also positioning its technology around upcoming European regulatory changes, including AMLR, and the broader push toward Open Finance and interoperable digital identity systems.
