We fund Public Interest Tech.

The application phase runs until 30 September 2022.

The Prototype Fund supports software developers, designers and other creatives in transforming their ideas from concept to software prototype. Whether society, education, environment or technical sovereignty – together we explore and test new ways for technical and social innovations as open source software from society and for society.

As individual developers or small interdisciplinary project teams, you will receive up to €47,500 over six months from the German Federal Ministry of Education and Research. With this funding you can write code and develop a first prototype of your software. We will also connect you with tech and other relevant communities, support you with coaching, and advise you on project implementation, communication, and sustainability.

Apply – as an individual developer or in a small team – with your idea for innovative open source software until September 30, 2022 (23:59) for the 13th round of the Prototype Fund. The call is open to all topics.

We explicitly encourage all people who belong to groups that have been underrepresented in software development to apply for funding. You can contact us at any time during the application period.

In the trend report, in which we take an exploratory look at current technological developments at the beginning of each round, we looked at legal tech. You can, but do not have to, address the topics in the report in your application.

The report focuses on the following questions: How is digitalization in the judiciary developing (inter-)nationally, who is involved, what are the challenges and what issues are being discussed in this context? Which potentials of and needs for public interest tech in the judiciary can be identified and can make a contribution with added social value?

We look forward to submissions that take an exploratory look at these questions. But all other ideas are also welcome in this open-topic call. Open call means that you can send us all project ideas in the area of Public Interest Tech and our four funding priorities Civic Tech, Data Security, Data Literacy and Software Infrastructure. The important thing is that they are public interest technologies – and you meet all the eligibility criteria. For a good idea of what this looks like in practice, check out the 272 current and past grant projects.

For us, it’s obvious that all innovations in the public interest must remain adaptable and accessible. That’s why we only fund open source projects. If you have questions about the application process or funding, you can find the answers in our FAQ.

Public Interest Tech

Developers from civil society create technologies that focus on the needs of users and are freely available. These technologies - regardless of their (financial) usability - form the basis of our (digital) coexistence and create added value for society.


Funding is available for independent programmers and small teams based in Germany. Each project is supported with a maximum of 47,500€. From 2016 to 2024, up to 25 innovative projects will be funded in 16 funding rounds.

Time frame
