What SEMAsystems GmbH does

SEMAsystems GmbH is a privately held, founder-owned German software engineering company founded in 2011 by Manuel Simmerl and Sebastian Gleißenner and registered at Amtsgericht Passau (HRB 8350). The company operates from two locations — its headquarters in Schönberg, Bavaria, and a regional office in Hamburg — and serves the DACH region (Germany, Austria, Switzerland). Its core offering is custom software development, spanning web applications (PHP, HTML5, JavaScript, Bootstrap), client software (C, C#, C++, Java), database systems (MySQL, MariaDB), and interface development (SOAP, REST/JSON, CSV), complemented by agile hardware development covering PCB layout, embedded programming, microcontrollers, sensors, and IoT prototyping.

The company's flagship product is RETTpro®, an established rescue service software that coordinates warehouse management and daily processes for emergency services, aid organizations, disaster protection facilities, and large leisure facilities across the DACH region. Beyond RETTpro, SEMAsystems delivers a portfolio of service offerings including login platforms with rights management, API and interface integrations, custom user tools, administration and duty roster software, data monitoring dashboards, and TÜV-certified ISO 27001 information security consulting. Hosting for own software projects is provided through a DIN 27001 certified data center.

Revenue is generated primarily through professional services (custom software development and information security consulting) supplemented by managed hosting and ongoing monitoring services. The go-to-market is consultative and sales-led, structured around an 8-step process from requirements analysis through funding examination, implementation, training, and ongoing update support. Customer segments are weighted toward emergency services and rescue organizations as the primary vertical, with secondary cross-industry work in digitalization and process optimization. No revenue, headcount, or external funding is publicly disclosed.
