Programme Thesis
The NGI Zero Commons Fund is a European Commission–backed initiative (€21.6M total, 2024–2027) administered by NLnet Foundation that awards small-to-medium grants (€5K–€50K, scalable to €150K for prior grantees) to open-source software, hardware, and research projects that strengthen the 'internet commons' — shared digital infrastructure that is more secure, decentralised, interoperable, and user-controlled. It exists to correct market failure in internet infrastructure: the belief that only through publicly funded open-source investment can civil society reclaim the internet from proprietary capture. Every project output must be released under a recognised free/open-source license, and all scientific outputs must be open access; the fund explicitly backs individual developers with no requirement for institutional affiliation, consortium structure, or prior grant history.
Selection Criteria
- **Hard knock-out (Stage 1 eligibility):** Proposal must align with the NGI vision; R&D must be the primary objective; there must be a 'clear European Dimension' (defined explicitly — EU/Horizon Europe-associated country residency is prioritised; non-EU applicants must demonstrate exceptional quality *and* a clear European dimension as an additional condition, not just a bonus)
- **Stage 1 weighted scoring (out of 7; must exceed 5.0 to advance):** 30% Technical excellence/feasibility | 40% Relevance / Impact / Strategic potential | 30% Cost effectiveness / Value for money
- **Stage 2 (strategic selection):** Reviewers ask targeted clarifying questions — differentiation vs. existing projects U/V/W, complicating technical factors, validation of claims, collaboration with complementary efforts, sustainability plan, upstream project posture, rate justification per task. Projects that cannot respond within the allocated window are moved to the next call rather than rejected outright.
- **Independent review committee:** Final shortlist is re-validated by external experts (academia, internet/open-source field, public sector) on eligibility and budgetary frugality.
- **Practical reviewer signals (from successful grantees):** Working code > white paper; specific milestone over vague deliverable; honest scope over inflated budget; connection to existing standards (IETF, W3C, OASIS, OSI-licensed ecosystems) is a strong positive signal; solo maintainers with demonstrated prior work are common winners.
Past Winners / Cohort Profiles
Funded cohorts (39–67 projects per bi-monthly call) are dominated by three archetypes: (1) **Infrastructure tool-builders** — solo developers or tiny teams shipping concrete open-source software with clear milestones, e.g., Python OpenPGP library, XMPP–Matrix gateway, SPARQL query evaluation engine, PDF redaction tooling, satellite imagery aggregation; (2) **Open hardware engineers** — PCB designers, chip architects, and embedded systems developers, e.g., optical trapping microscope (Arkin), open battery management system (OpenBMS), RISC-V processor core (Coreblocks), open ASIC instrumentation amplifier; (3) **Protocol and network-stack contributors** — e.g., MILAN open audio networking, bhyve hypervisor, LinuxBoot, Managarm microkernel, mesh networking tools. The April 2026 round (57 projects, ~€1.4M) and March 2026 round (44 projects) confirm this pattern: hardware/manufacturing, network infrastructure, OS/firmware, and data/AI tooling dominate. Notably, 'open AI and open data' tooling is an expanding category in recent cohorts (document conversion, open model infrastructure, reproducibility tooling), and open science tools appear occasionally — but the *research science itself* is never the funded deliverable; the *tool or software infrastructure* is. Named examples: Arkin, LibreCellular 5G, OpenBMS, Coreblocks RISC-V, Remote Sniffnet, VACASK, Bromal (lightweight Matrix server), YunoHost OIDC, Zrythm DAW.
Ideal Candidate Fingerprint
The platonic ideal NLnet Commons Fund applicant is a technically credentialed solo developer or small team — often European but not required — who has already built a working proof-of-concept in open-source and is seeking modest funding (€10K–€50K) to push it to production maturity: documentation, test coverage, packaging, security audit readiness, and community adoption. Their proposal centres on a *specific, concrete software or hardware deliverable* (not a research paper, not a fellowship, not salary support) with 3–5 well-defined milestones over 6–12 months, a frugal budget with explicit rates, and a clear argument for why their tool benefits the European internet commons even if they are based elsewhere. They connect their work to at least one established open-source ecosystem, standards body, or prior NLnet cohort project.
Recommended Framing
Eniola's strongest angle is to position GATE, TOPOLOGIX, and IMPRINT as *open-source scientific infrastructure tools for the European research internet* — not as outputs of her pharmacology research programme — and to propose a specific, scoped software deliverable within one of them. The highest-fit project is **TOPOLOGIX** (Apache/OSS-compatible TDA drug-protein interaction tool): persistent homology + bipartite simplicial complexes applied to hERG cardiotoxicity is genuinely novel open-source scientific software with no direct equivalent in the European open-source bioinformatics ecosystem, and it can be argued as serving EU pharmaceutical safety researchers and the open-data commons. The proposal should request a specific engineering milestone (e.g., 'publish TOPOLOGIX as a pip-installable Python library with documented API, CI test suite, and hERG benchmark dataset under CC BY 4.0') rather than funding Eniola's salary or research career, name two or three European research groups (e.g., a German or Austrian cheminformatics lab aligned with her MUG application) as target end-users or collaborators to satisfy the European dimension requirement, and lead with the open-source software deliverable in the abstract — CCT and IMPRINT can appear as ecosystem context but should not be the primary claim.
Watch Out
1. **FUND IS CLOSED — critical showstopper.** The 13th and final call of the NGI Zero Commons Fund closed June 1, 2026. NLnet's own website states: 'No more new applications are sought for this fund.' The programme page explicitly redirects applicants to other open calls (currently only NGI TALER and NGI Fediversity, neither of which is relevant). The successor programme ('Open Internet Stack') is in transition and temporarily paused as of mid-June 2026. Eniola cannot apply to this fund in its current form.
2. **Non-EU geographic penalty.** Nigeria is outside the EU and all Horizon Europe associated countries. The eligibility page explicitly states that EU/Horizon Europe residents receive priority on equal proposals, and non-EU applicants must satisfy an *additional* 'clear European dimension' requirement — not merely a bonus criterion. With a Nigerian address and no European institutional affiliation until October 2026 at the earliest, Eniola faces a structural disadvantage regardless of proposal quality.
3. **Project type mismatch.** The fund funds software/hardware deliverables, not researcher fellowships, salary support, or scientific publication pipelines. Eniola's primary funding need (fellowship, living stipend, research support) does not match what NLnet funds. Her open-source tools (GATE, TOPOLOGIX, IMPRINT) are the fundable surface area, but they would need to be scoped and presented as standalone engineering projects, not as vehicles for her CCT research career.
4. **No prior NLnet history.** First-time applicants are capped at €50K and compete against applicants with established NLnet track records who are eligible for scale-up. This is a moderate disadvantage, not a disqualifier.
5. **Scholarship aggregator data may be stale.** The ScholarshipBob listing for this programme may reflect an earlier call — the 'OISI' track label does not appear on NLnet's own website, suggesting the aggregator applied its own categorisation. Deadline and status data from that source should not be trusted without verification against nlnet.nl directly.
