NLnet Foundation
NLnet offers financial support for technical development projects that use open licenses and standards, with a focus on open internet technologies, with grants up to €50,000.
The NLnet Foundation provides financial grants to support projects focused on technical development, particularly those contributing to an open internet stack. Projects must ensure that software, hardware, and content are released under open licenses and adhere to open standards. NLnet manages several theme funds, each with specific requirements, but a general open call is also available. The foundation is particularly interested in proposals that demonstrate a strong European dimension for its EU-supported funds, usually requiring applicants to be primarily from Horizon Europe-eligible countries. They explicitly discourage AI-generated projects or proposals. The application process emphasizes brevity and clarity, focusing on the core ideas, technical challenges, ecosystem engagement, and the applicant's relevant experience. NLnet aims to foster digital autonomy and support the growth of free and open-source software and technology, encouraging innovative solutions for a more open and secure internet.
