NLnet Foundation funds open-source internet infrastructure through equity-free grants backed by an endowment, not venture capital term sheets. For maintainers, that means a funding path that does not require donation campaigns, growth metrics, or a monetization roadmap. The tradeoff is dependence on the continued political and budgetary will behind the European Union’s Next Generation Internet programme and on NLnet’s own grant cycle.
What is NLnet, and how is it different from venture capital?
NLnet is a Dutch nonprofit, or Stichting, headquartered at Amsterdam Science Park, that has supported open-internet technology since 1997, after helping spread internet access through Europe in the 1980s. According to Wikipedia’s NLnet entry, it is recognized as a Dutch public-benefit organization, an ANBI, and it disburses grants rather than taking equity. That structural fact changes what a grantee is signing up for. A venture capital investment implies a return expectation, board influence, and eventually pressure to commercialize or exit. A grant from NLnet implies deliverables, reporting, and a requirement that results be released under FOSS licenses, but it does not imply a cap table event.
The foundation also runs an open call in which anyone worldwide can submit proposals to improve the internet, alongside its themed funds. This is closer to a research council or arts council model than to a seed round. Applicants do not pitch market size or customer acquisition cost. They pitch public benefit, technical feasibility, and alignment with the fund’s goals. The grant size is modest by venture standards, but so is the overhead of staying aligned with the funder. A maintainer who wants to build a protocol that makes email more private does not need to explain how that protocol will become a billion-dollar company. They need to explain how it will work, who will use it, and why the internet is better if it exists.
Where did NLnet’s money come from?
The financial base for NLnet’s grant-making traces to a single transaction: the 1997 sale of its commercial ISP subsidiary, NLnet BV, to UUNET, which is now part of Verizon. That sale produced an endowment that has underwritten roughly three decades of no-equity grants, as described in Wikipedia’s NLnet entry. An endowment is not a fund that needs to be replenished by limited partner capital every few years. It does not carry carried-interest math or liquidation preferences. It just needs to be managed conservantly enough to keep disbursing at a sustainable rate.
This matters because it decouples NLnet’s choices from the venture cycle. When venture markets tighten, VC-backed open-source projects face down rounds, layoffs, or pressure to add proprietary tiers. NLnet’s model is not immune to market conditions, but its endowment means it is not pulling grants because a fund’s limited partners suddenly want liquidity. The constraint is the endowment’s real return and the foundation’s own strategic priorities, not an investor’s distribution schedule. That stability is especially valuable for infrastructure work, which often needs years of refinement before it is ready for wide adoption. A DNS resolver or a privacy-preserving payment protocol does not ship a minimum viable product in twelve weeks and then pivot. It needs sustained attention across multiple release cycles.
What is NLnet funding now?
As of June 21, 2026, NLnet’s website lists six active NGI-era funds: NGI TALER for privacy-preserving payments built on GNU Taler; NGI Fediversity for hosted cloud services; Restack for the Open Internet Stack; CodeSupply for cybersecurity and supply-chain and license compliance; ELFA for encrypted local-first architecture; and the NGI Zero Review programme. The NGI Zero Review programme operates within the larger Next Generation Internet initiative, explicitly coupling NLnet’s review, hardening, and compliance services to the EU’s NGI programme.
The portfolio is heavy on plumbing, not applications. Projects NLnet has funded include Mastodon, Peertube, Galene, WireGuard, Tor, Namecoin, Jitsi, nftables, Mobilizon, DNSSEC, GNUnet, NoScript, CryptPad, and the GPLv3 drafting process, according to Wikipedia’s NLnet entry. NLnet’s infrastructure pedigree also includes founding NLnet Labs in 1999, which produced NSD, Unbound, OpenDNSSEC, getDNS, and Krill, and co-founding the AMS-IX exchange and the .nl registry SIDN. These are not consumer apps chasing network effects. They are protocols, resolvers, exchanges, and registries: the kind of work that is hard to monetize directly but that every networked application eventually depends on.
What does the grant model select for, and what does it cost?
The grant model selects for projects whose value is diffuse and long-term rather than concentrated and near-term. A protocol like WireGuard or a resolver like Unbound does not generate recurring revenue per user. Its value accrues to the whole network. Venture capital generally avoids this profile unless there is a plausible adjacent business, such as managed hosting or support contracts. Grants do not require that adjacent business. They can fund the core work directly.
The cost of this model is a different dependency. Instead of depending on investors, grantees depend on the continuity of the grant programme. The NGI-era funds are tied to the EU’s Next Generation Internet programme. If NGI funding is reduced, restructured, or not renewed, the themed funds that depend on it would shrink or close. NLnet also spends from its own endowment, so not every grant is EU money, but the NGI-era portfolio is explicitly coupled to the EU programme. That coupling is the structural tradeoff: freedom from commercial pressure, but reliance on public-budget politics.
Grantees also face the ordinary bureaucracy of public funding: reporting, milestones, and compliance. That is not lighter than venture governance, just different. A VC-backed founder might spend hours on board decks and investor updates; a grant-funded maintainer might spend hours on reports and reimbursement paperwork. The power dynamic is different, but the administrative load is real. The difference is who reads the report. A venture board wants to see growth and path to revenue. NLnet wants to see technical progress and public benefit.
How does this diverge from US venture-backed open source?
US venture-backed open source and EU grant-funded open source are converging on the same code but diverging on the economics. Venture-backed projects start with a permissive license, community contributions, and often a vague promise that monetization will come later. Eventually the monetization pressure arrives. It usually arrives as a license change, a managed-cloud offering, a feature gate, or a shift toward proprietary add-ons. The projects that survive this transition are the ones whose architecture or user base supports a clear commercial path.
Grant-funded projects skip that transition. They do not need to find a business model because they are not businesses. They can remain FOSS, stay protocol-first, and optimize for standards adoption rather than revenue per seat. Over time this selects for different kinds of projects. VC-backed open source favors projects that can plausibly become platform companies or infrastructure vendors. Grant-funded open source favors projects that solve collective-action problems for the internet: privacy, interoperability, decentralization, and robustness.
This divergence is not absolute. Some projects mix funding. Some grant-funded projects later seek commercial sustainability. Some VC-backed projects release genuinely public-goods infrastructure. But the funding source shapes the incentives, and the incentives shape the roadmap. A grant-funded project can afford to say no to a feature that would help one paying customer but hurt the protocol. A VC-backed project often cannot. The result is two ecosystems that share tools and contributors but optimize for different outcomes.
What remains uncertain?
The biggest near-term uncertainty is programme continuity. The NGI programme is a policy choice, not a permanent institution. Future budgets depend on European Commission priorities, member-state politics, and the continued argument that open-internet infrastructure is a public good worth funding. NLnet’s own endowment provides some insulation, but the six active funds listed on NLnet’s website are largely framed within the NGI era.
There is also a specific factual gap. The headline figure of 67 newly funded projects, which appears in the title, is not corroborated by the sources retrieved as of June 21, 2026. Neither NLnet’s website nor Wikipedia’s NLnet entry contains a June 2026 announcement or a count of 67 projects. The structural argument stands without that number, but the number itself should be treated as unverified until a primary NLnet announcement page is located.
Frequently Asked Questions
Who can apply to NLnet, and what does a typical application look like?
NLnet accepts proposals through both themed funds and an open call, and there is no requirement to be a Dutch or EU organization. A strong proposal emphasizes public benefit, technical feasibility, and alignment with fund goals rather than market size or revenue projections. Grant amounts are typically small compared with venture rounds, so the funding suits discrete, well-scoped infrastructure work more than multi-year product builds.
How does NLnet’s funding differ from corporate open-source foundations like the Linux Foundation?
NLnet originates from a nonprofit endowment and gives direct, project-specific grants without taking equity or board seats. Corporate-backed foundations such as the Linux Foundation rely heavily on member dues and tend to provide governance, events, and trademark hosting rather than direct R&D grants for individual projects.
What reporting and compliance obligations do NLnet grantees face?
Grantees must release results under FOSS licenses, meet agreed milestones, and submit progress reports. Unlike venture governance, there are no cap-table events or growth targets, but the paperwork burden is real: maintainers can spend significant time on reimbursement documentation and compliance rather than code. This structure favors projects that can define clear, verifiable technical milestones instead of open-ended exploration.
Could NLnet’s endowment-plus-grant model survive a major shift in EU tech policy?
NLnet’s own endowment from the 1997 UUNET sale provides a buffer, so the foundation could continue some grants even if NGI-era funds were reduced. However, the six active funds listed in mid-2026 are explicitly tied to the EU’s NGI programme, so a sharp policy shift would force NLnet to either shrink themed funding or draw more heavily on its endowment, potentially reducing the number or size of future grants.
Why might a maintainer choose venture capital over an NLnet grant?
Grants are modest, milestone-bound, and ill-suited to work that needs rapid hiring, marketing, or multi-year product development. A project that must reach users quickly, build a sales team, or sustain a large full-time staff may need venture capital despite the eventual pressure to monetize. NLnet fills a different niche: focused technical work whose value spreads across the whole network rather than returning to a single company.
