Funding Models for Shared Infrastructure

Digital public infrastructure only becomes reliable when the funding behind it is reliable. Many of the systems that civil society depends on today emerged from volunteer labour, small grants or short bursts of institutional enthusiasm, and the result is an ecosystem where critical tools often sit on unstable foundations. The organisations that have endured the longest tend to be those that found sustainable models early. Mozilla’s long running support for open source is an example. Through the Mozilla Open Source Support programme, the organisation has channelled institutional and philanthropic resources into essential internet tools for nearly a decade, providing one of the few dependable funding anchors for shared digital goods.

A different approach can be seen in Barcelona’s stewardship of Decidim, the open source participation platform. Decidim is funded and governed as part of the city’s democratic infrastructure rather than as a standalone tech project. This gives it a degree of durability that most civic tech tools never achieve. The project’s governance model includes community representation, transparent decision making and long term planning, all supported by municipal commitment. It shows how public institutions can sustain digital commons at scale when funding, governance and mission align.

Other models distribute the burden more widely. Open Collective allows community groups, grassroots networks and open source teams to receive and manage funds through a shared fiscal hosting structure. Instead of each group building its own administrative machinery, Open Collective provides transparency, accounting and governance support, funded through small fees from participating organisations. This cooperative model has become a backbone for hundreds of civil society and open source communities that would otherwise struggle with basic financial infrastructure.

Hybrid models are also emerging. The Matrix Foundation, which oversees the Matrix communication protocol, blends institutional adoption, philanthropy and community support. Matrix is used by governments, NGOs and public sector bodies across Europe, and this diversity of users has helped spread responsibility for its long term maintenance. The Open Tech Fund sits in a similar space, providing globally distributed funding for security tools, censorship circumvention and open infrastructure used by journalists, activists and civil society groups under pressure. Both cases illustrate that resilient infrastructure rarely depends on a single funding stream. It is sustained through a network of institutions, funders and users who share responsibility over time.

A growing number of projects also explore blockchain based or DAO-enabled funding mechanisms for public digital goods. These systems treat infrastructure as a shared resource and use transparent on-chain treasuries or community voting to allocate maintenance budgets. They allow for continuous, small scale contributions from a wide pool of stakeholders rather than relying solely on grants or public procurement. This approach remains experimental and is not suitable for every context, but it offers lessons on how funding, governance and long-term maintenance can be tied together in a more predictable and accountable way.
