Become a sponsor to Typelevel
We created the Typelevel Foundation in 2025 to strengthen the long-term sustainability of the Typelevel ecosystem and to further our mission of advancing functional programming while growing an inclusive community of curious and passionate developers.
If your organization relies on Typelevel libraries, please consider sponsoring the Foundation to help ensure ongoing maintenance, development, support, and community events. We would love to talk to you; please reach out!
Support from community members like you helps keep Typelevel open, independent, and thriving.
