Stichting NLnet funds technical public-interest work that strengthens an open, secure, and resilient internet. It is especially interested in open standards, free and open-source software, privacy-preserving technologies, digital rights, open science, and open data, often backing infrastructure and protocol-level projects rather than direct service delivery. Its grants tend to support developers, researchers, and foundations building reusable open technology with broad ecosystem impact.
