“Can a vertical fintech own the full revenue cycle — intake, billing, factoring, payments — for German medical practices?”
Nelly is a Berlin-based vertical SaaS company building a financial OS for medical practices in Germany. It started with digital patient intake and billing for doctors and has expanded into embedded factoring (digital invoice financing) and payment acceptance, partnering with Adyen for payment infrastructure and with Vereinigte Volks- und Raiffeisenbank for factoring.
Nelly discloses Vereinigte Volks- und Raiffeisenbank as its sponsor bank, according to the Embedded Finance Index 2026.
Nelly does not disclose a bank charter of its own; its banking services are provided through Vereinigte Volks- und Raiffeisenbank.
Nelly processes payments through Adyen.

Nelly was founded by Lukas Eicher and is headquartered in Berlin, Germany.
