💰 Funding Details

NGI Fediversity Open Call (2025-08F)


Overview

The NGI Fediversity open call (Call ID: *HORIZON-CL4-2023-HUMAN-01-12*) is a cascade-funding opportunity under Horizon Europe that supports projects advancing an open, trustworthy and inclusive Fediverse—a constellation of decentralised social platforms based on open standards such as *ActivityPub*.


Key Features

* Cascade funding model – applicants sign a sub-grant agreement with the NGI Fediversity consortium rather than the European Commission.

* Budget flexibility – although the framework does not impose a strict ceiling, typical sub-grants range between €50 000–€150 000; larger amounts require strong justification.

* Eligible beneficiaries – SMEs, start-ups, research groups, NGOs and individual innovators established in your country or any Horizon Europe associated state.

* TRL focus – projects at TRL 3–6, moving concepts from validated research towards demonstrators and pilot deployments.

* 100 % funding rate – costs are reimbursed in full, with a simplified lump-sum reporting scheme.


Strategic Fit

NGI Fediversity targets technologies and governance models that foster:

1. Interoperability across decentralised platforms.

2. User agency & privacy (self-sovereign identities, consent-based data sharing).

3. Content moderation tooling that is community-driven and transparent.

4. Diversity & inclusion in both technological design and community engagement.


Why it matters for your country

* Leverage your country's vibrant open-source communities.

* Connect with your country research institutions specialising in decentralised architectures.

* Position your country SMEs at the forefront of ethical digital transformation.

🇪🇺 Strategic Advantages

EU-Wide Advantages & Opportunities for **NGI Fediversity open call (2025-08F)**


Single Market Access

Why it matters: The EU’s single market offers friction-less circulation of digital services across 27 Member States and 450 + million end-users.


- Immediate multi-country reach: Solutions piloted under NGI Fediversity can launch simultaneously in all EU/EEA markets without separate national conformity assessments, reducing go-to-market time by up to 12-18 months.

- Network effects at scale: Federated, decentralised internet services draw higher value from large user bases; the ability to tap the full EU consumer pool accelerates critical-mass adoption.

- Public-sector demand: Many Member States are actively procuring open, privacy-enhancing digital tools. A pan-EU footprint positions beneficiaries for subsequent cross-border public procurement opportunities enabled by the revised EU Public Procurement Directive.


Cross-Border Collaboration

Why it matters: NGI cascade funding explicitly encourages consortia or multi-actor pilot projects.


- Multinational consortia eligibility: Beneficiaries can team up with SMEs, research labs, civic-tech groups and open-source communities from different Member States, strengthening proposals with complementary expertise.

- Knowledge exchange & talent mobility: Horizon Europe’s cross-border cost eligibility enables secondments, staff exchanges and joint research infrastructures, lowering administrative hurdles for distributed teams.

- Shared testbeds: Access EU-wide NGI experimentation platforms (e.g. Fed4FIRE+, Gaia-X hubs) for large-scale interoperability trials under uniform technical standards.


EU Policy Alignment

Why it matters: Proposals that reinforce flagship EU strategies are scored higher and receive stronger political backing.


- Digital Decade 2030: Fediverse technologies underpin sovereign and open digital infrastructures—directly addressing the EU target of doubling the uptake of secure, interoperable platforms.

- European Green Deal: Decentralised architectures can cut data-centre energy concentration and encourage edge computing, contributing to the EU goal of climate-neutral digital technologies by 2030.

- Data Act & DSA/ DMA compliance: Projects aligning with new EU data-sharing & platform governance rules gain first-mover advantages before full enforcement.


Regulatory Harmonisation

Why it matters: One ruleset = lower compliance costs.


- GDPR-ready by design: Building privacy-preserving, federated services from inception avoids later retrofitting for data-protection compliance across 27 different regimes.

- eIDAS 2 interoperability: Seamless integration with EU Digital Identity Wallets unlocks trust services market worth €17 bn (2022 COM estimate).


Pan-European Innovation Ecosystem

Why it matters: Horizon Europe links beneficiaries to Europe’s premiere RTD facilities.


- Access to research infrastructures: Leverage pan-EU labs (e.g. CERN openlab, EGI) for high-performance computing and open-source collaboration.

- Venture & incubator networks: Connection to EIT Digital, NGI-atlantic, and regional Digital Innovation Hubs increases follow-on investment probability (average 2.7× leverage according to EIC data).


Funding Synergies

Why it matters: NGI cascade grants can act as a springboard to larger EU instruments.


- EIC Transition & Accelerator: Proven Fediversity pilots can apply for €2.5–15 m equity/blended finance, shortening TRL-to-market cycle.

- DEP (Digital Europe Programme): Ready-to-scale solutions may secure procurement-type financing for EU-wide deployment of common data spaces and open-source middleware.

- ERDF & RRF coherence: Regional authorities can co-invest in local nodes of a federated network, using structural funds to match Horizon contributions.


Scale & Impact Potential

Why it matters: The societal value of an open, decentralised internet multiplies with geographic coverage.


- Standard setting: EU-wide pilots can establish de-facto interoperability standards adopted globally, reinforcing European technological sovereignty.

- Policy influence: Successful demonstrators become reference implementations for future EU digital governance frameworks, shaping long-term regulatory landscapes.

- Replicability: Modular, open-source outputs mandated by NGI are easier to translate into additional languages and legal contexts, easing further expansion to Associated & Neighbouring countries.


Strategic Value at EU Scale

Operating under the NGI Fediversity open call enables beneficiaries to:


1. Reduce market fragmentation risks and compliance costs through the single market and harmonised regulation.

2. Harness continent-wide network effects essential for federated platforms.

3. Leverage unrivalled cross-border talent, research infrastructures and funding escalators unavailable at purely national level.

4. Position solutions at the heart of EU strategic priorities, maximising both political support and commercial uptake across Europe.
