A12 Platform

mgm technology partners GmbH is making the source code of the A12 AI Low Code Platform available from 27 May 2026. The Community Edition is now available on openCode and GitHub. The A12 platform has proven itself over many years on highly complex public administration projects, such as ELSTER. A12 enables the creation of complex specialist applications using model-based software development and low code. By opening up the source code, all organisations and companies can now benefit from this experience and operate their applications with digital sovereignty.

AI-assisted code generation promises speed — but without clear architectural boundaries, the result is risk, not results. Generated code isn't inherently secure, maintainable, or testable. What matters is the framework it's produced in: precise architectural constraints limit what's possible so that entire classes of errors are structurally eliminated. How this works in practice — and why A12 acts as a safety net.

On May 12, 2026, Markus Michels, Senior Open Source Program Manager at mgm technology Partners, will be a speaker at the live webinar “How Can the Federal Government, States, and Municipalities Work Together to Achieve Digital Sovereignty?” on eGovernment.de.

The IT Planning Council has set the course with its resolution on the Federal Target Architecture for Mailbox and Communication Solutions (ZaPuK)—but the real challenge begins now: Hundreds of specialized procedures and portals must be migrated, integrated, and reimagined. mgm technology partners demonstrates how this can be achieved with open source, a clear architectural framework, and responsible AI deployment.

The A12 Enterprise AI Low Code Platform will soon be available as open source. In close coordination between the Bavarian State Office for Taxation...

The recruitment of qualified young talent is one of the key challenges in the tax profession. Against this backdrop, the Federal Chamber of Tax Consultants (Bundessteuerberaterkammer), together with mgm technology partners, has further developed a platform that centrally consolidates the administration and publication of training positions, internships, and working student positions as well as recruitment events for young professionals.

Complexity, speed, and regulation: IT and digital projects often face intense pressure. In this environment, robust project standards are essential for achieving predictable outcomes, reliable quality, and efficient collaboration. The white paper "mgm A12 Project Standards: Delivering Software Projects with the A12 Development Platform" provides a concise, practical overview of how mgm applies and continuously improves its standards in A12 projects, from initial conception to operations.

The digitization of public administration is the central transformation on the path to state modernization. The Online Access Act (OZG) requires the federal government, states, and municipalities to offer administrative services digitally. However, digitized application forms are only the first step. Only complete, seamless end-to-end digitization creates real added value – for citizens, businesses, and public authorities.

Starting July 8, 2025, einfachELSTERplus will make filling out tax returns easier than ever – with an interactive interview mode. As a long-standing digitalization partner of the German tax authorities, mgm technology partners played a key role in implementing this new service.

In complex system landscapes, seamless data integration plays a central role. Whether connecting new business applications or implementing large-scale initiatives like register modernization, data transformation and mapping form the backbone. A12 takes a new approach: business units model their data flows independently—without programming—directly in the Simple Model Editor (SME).
