Open-source communities, much like public infrastructure, depend heavily on consistent support and maintenance, which are often underprovided, leading to outdated technology and diminished community benefits. Founding organizations, companies established by key contributors to open-source projects, play a critical role in addressing this sustainability challenge by being responsible stewards that ensure continuous investment and modernization of the technology. These organizations are crucial for creating a sustainable business model that supports ongoing development, maintenance, and innovation, thus fulfilling a social contract with the community to keep the technology cutting-edge. Gatsby, as an example, demonstrates its commitment to open-source by investing in engineering resources, launching Gatsby Cloud for commercialization, and promoting modern web development standards to ensure the health and vibrancy of its ecosystem.
