deepinvoice Receives 700,000 Euros for AI-Powered Medical Billing

The Münster-based startup deepinvoice, founded as recently as 2026, has closed a funding round totaling 700,000 euros. The round is led by BDOC Plus AG as the lead investor. In addition to NRW.BANK, which is participating through its investment program NRW.SeedCon, the Augenzentrum am Blauen Wunder in Dresden and business angel Burkhard Awe are also investors.

With the fresh capital, the company plans to further develop its AI-based software for automated medical billing and make it available for additional medical specialties. In addition, the company aims to enable cloud-based use and expand its team.

The two founders, Arne Tönjann and Lukas Talar, aim to use deepinvoice to solve a problem that plagues many medical practices: the high administrative burden associated with documenting and billing medical services. In particular, correctly assigning treatments provided to the corresponding billing codes has often required manual work and specialized expertise.

Artificial Intelligence Aims to Automate Billing Processes

deepinvoice’s software begins directly with the physician’s documentation. Using artificial intelligence, the documented medical services are analyzed and automatically assigned to the appropriate billing codes.

In doing so, the system takes into account both the Fee Schedule for Physicians (GOÄ), which is particularly relevant for private medical services, and the Uniform Assessment Standard (EBM), which governs the billing of services provided by physicians under contract within the statutory health insurance system.

The software then verifies the results against predefined rules and transfers them to the respective practice management system. According to the company, this approach allows the entire billing process to proceed largely without manual intervention.

The first area of application is ophthalmology. The solution is aimed not only at individual medical practices but also at medical care centers and hospitals.

For medical facilities, automation could offer several advantages. In addition to potential time savings on administrative tasks, standardized processes are expected to help reduce billing errors and make more efficient use of existing personnel resources.

However, the actual savings in day-to-day practice are likely to depend on the quality of medical documentation, integration into existing software systems, and the respective billing processes.

NRW.BANK Supports Expansion into Additional Specialties

Through its investment via the NRW.SeedCon program, NRW.BANK is supporting another technology-oriented company from North Rhine-Westphalia in an early stage of development.

The development bank sees the technology’s potential to open up new fields of application beyond ophthalmology. Automated billing solutions could become increasingly important, particularly in medical facilities facing rising administrative costs and limited staffing capacity.

The composition of the funding round is also noteworthy. With BDOC Plus AG and the Augenzentrum am Blauen Wunder Dresden, participants from the medical field are involved. This provides deepinvoice not only with financial resources but also with access to potentially relevant industry knowledge and practical experience from day-to-day healthcare operations.

Cloud Solution and Expansion into Other Medical Specialties Planned

In the next phase of development, deepinvoice aims to expand its technology into a plug-and-play solution that is as easy to integrate as possible. The goal is to reduce the technical effort required for implementation in medical practices and other healthcare facilities.

In addition, the startup plans to offer its software via the cloud. This would allow the solution to be used independently of individual local installations in the future and make it easier to adapt to different practice structures.

At the same time, the technology—which has so far been focused on ophthalmology—is to be adapted for other medical specialties. In particular, accommodating different documentation requirements and billing rules is likely to play an important role.

Issues related to data protection and the secure processing of sensitive health data will also be significant in the planned use of the cloud.

With this completed funding round, deepinvoice has secured the financial foundation for these next steps in its development. Whether the technology can establish itself in the market in the long term will depend largely on how reliably the automated coding works and how easily the software can be integrated into existing practice workflows.
