Our Services Related to the Matrix Protocol

TI Messenger Client Development

We develop native and cross-platform TI Messenger clients in accordance with gematik specifications. In doing so, we implement the technical requirements for interoperability, end-to-end encryption, and the nationwide address book (VZD-FHIR Directory).

Matrix Server & Backend Infrastructure

We design and implement the server-side infrastructure for your Matrix-based communication solution: home server setup, federation configuration, and API interfaces. Scalable and compliant with the telematics infrastructure.

Integration with Existing Systems

Would you like to integrate messaging functionality into your existing health app, DiGA, or telemedicine platform? We seamlessly integrate TI Messenger features using the TI-M Connect specification or custom Matrix APIs.

Security & Encryption

We implement the cryptographic requirements of the Matrix protocol: end-to-end encryption, key management, and the elliptic curve cryptography (ECC) required by the BSI, in compliance with all data protection regulations.

gematik Certification Support

From preparing the self-administered tests to conducting interoperability testing and submitting your application: We guide you through the entire gematik approval process and ensure that your solution meets all requirements.

What is TI Messenger and why use the Matrix protocol?

TI Messenger is the communication solution specified by gematik for the German healthcare system. It enables secure, cross-sector real-time communication between healthcare providers, facilities, and insured individuals. It is comparable to well-known messaging services but complies with the requirements of the telematics infrastructure (TI).

Gematik has chosen the Matrix protocol as its technical foundation: an open, decentralized communication standard developed by the Matrix.org Foundation. Matrix offers end-to-end encryption, a federated architecture, and full interoperability between different providers—features that are essential for the healthcare sector.

Three product variants for different applications:

TI-M Pro

Target Audience:
Service Providers & Facilities

Scope of Use:
Cross-sector communication among healthcare professionals (e.g., doctor-to-doctor, hospital-to-practice)

TI-M ePA

Target Audience:
Insured Individuals & Health Insurance Companies

Scope of Use:
Communication between insured individuals and their service providers via the ePA app

TI-M Connect

Target Audience:
Third-Party Providers & App Developers

Scope of Use:
Integration of messaging functionality into DiGA, patient portals, or telemedicine platforms

The TI-M Connect variant, in particular, gives manufacturers of health apps, digital health applications (DiGA), and telemedicine platforms the ability to integrate secure messaging features directly into their existing products.

Frequently Asked Questions About the Matrix Protocol and TI Messenger

What is the Matrix Protocol?

The Matrix Protocol is an open, decentralized communication standard developed by the Matrix.org Foundation. It enables secure, real-time communication with end-to-end encryption and is used by gematik as the technical foundation for the TI-Messenger in the German healthcare system. Its decentralized architecture prevents vendor lock-in and ensures interoperability between different providers.

What advantages does the Matrix protocol offer over proprietary solutions?

The Matrix protocol is an open standard with broad community support. Unlike proprietary solutions, it offers full interoperability, federated identity management, and a decentralized architecture. Of particular relevance to the healthcare sector: There is no central operator with access to communication data, and different TI Messenger providers can communicate seamlessly with one another.

Do I need a gematik certification for my TI Messenger?

Yes. Every TI Messenger that is to be connected to the telematics infrastructure requires approval from gematik. The approval process includes self-conducted tests, interoperability demonstrations, and a security assessment by an accredited assessor.

Can I integrate TI Messenger functionality into my existing app?

Yes, we’ll assist you with the technical integration using the Matrix client-server APIs.

How is the security of communications ensured?

TI Messenger uses the end-to-end encryption provided by the Matrix protocol. Messages are encrypted on the user’s device and can only be decrypted by the recipient. Even the server operator has no access to the content. Since January 1, 2026, the use of elliptic curve cryptography (ECC) has also been mandatory as the encryption technology recommended by the BSI.

Does QuickBird Medical also develop solutions outside of TI Messenger?

Yes. The Matrix protocol is suitable not only for TI-Messenger but also for any secure communication solution in the healthcare sector. We develop Matrix-based team communication solutions for hospitals, internal messaging systems for healthcare organizations, and custom chat features for health apps, regardless of gematik certification.

Your Path to a Matrix-Based Communication Solution

1. Requirements Analysis & Specification

Together with you, we analyze your requirements and the planned area of application: Which TI Messenger variant is appropriate? Which systems need to be integrated? Based on this, we create a detailed technical specification tailored to the current gematik requirements.

2. Architecture & Design

We design the system architecture for your communications solution: Matrix home server topology, client architecture, encryption strategy, and interface planning. In doing so, we take into account the federated structure of the Matrix protocol and the requirements of the telematics infrastructure.

3. Development & Integration

Our development team implements the solution using an agile approach, from client-side development and backend infrastructure to integration with your existing systems. End-to-end encryption, interoperability testing, and comprehensive documentation are all standard features of our process.

4. Registration & Operation

We guide you through the gematik certification process: independent testing, interoperability demonstrations, and security assessments. Once certification is granted, we support you with the rollout and are available to assist with maintenance and further development.
