In addition to the thousands of individuals who contribute to the Julia project in their personal capacities, we are grateful to a large number of companies and organizations that are supporting the continued growth of the Julia project and ecosystem.
The following organizations have employed Julia core developers whose full-time responsibility is Julia development and maintenance. We are grateful for their commitment to improving the long-term sustainability of the Julia project.
JuliaHub was founded by the creators of the Julia project and continues supporting the ongoing development of Julia by employing a significant number of Julia core developers.
Relational AI uses Julia heavily in their product offerings and employs several developers focusing on core Julia development, particularly around improvements to GC and observability.
MIT's Julia Lab was the original home of many Julia core developers.
Note that while these organizations are employing Julia core developers, decision making authority within the project rests solely with individual core developers and not their employers. For more information, see the <a href="/governance/">governance</a> page.
As a project, Julia encompasses more than just a repository on GitHub. Providing a seamless user experience to the Julia community requires a significant amount of infrastructure. Running this infrastructure is not cheap and we are grateful to these organizations for providing compute credits, services, hardware and other support essential for keeping Julia running:
AWS provides a substantial amount of free compute credits every year that powers major parts of our CI and package management infrastructure.
Fastly provides the Julia project with free CDN services
Discourse is providing a 50% discount on the hosting fees for https://discourse.julialang.org/
MacStadium is hosting a free M1 Mac mini for CI
ARM/Equinix are providing free access to Aarch64 machines for CI
IBM and OSU OSL are providing free access to IBM POWER systems for CI
Microsoft Azure is providing free credits improving package server latency to Microsoft Azure customer, most notable GitHub Actions
JuliaHub is maintaining data center space for the project and providing a significant number of CI machines
MIT's Julia Lab is maintaining data center for the project space and providing a significant number of CI machines
NVIDIA has provided both JuliaHub and the Julia Lab with a significant number of free GPUs across various generations of NVIDIA products
Buildkite provides a free Buildkite account for use in Base Julia CI
A number of organizations and funding agencies are or have provided direct funding for Julia maintenance.
NASA is funding efforts towards the creation of high quality released under award number 80NSSC22K1740. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Aeronautics and Space Administration.
Over the years, Intel has provided significant funding continuing to support a small development contract for maintenance of Julia on Intel platforms and accelerators.
Julia receives individual donations from a larger number of individuals through GitHub sponsors and NumFocus
In addition, there are a large number of organizations funding research primarily conducted in Julia or funding the specific development of certain Julia features. Funding agencies for these efforts include NSF, DARPA, NIH, and the FAA. However, they are not listed here, as this list only includes such funding directly dedicated to ongoing Julia maintenance.
The following organizations have previously directly funded Julia development and maintenance:
Lincoln Laboratory: Dr. Jeremy Kepner is the founding sponsor of the Julia project.
The annual JuliaCon conference raises money through sponsorship and ticket sales. Excess money after expenses (if any) become part of the general Julia fund at NumFocus, which is used to cover miscellaneous hosting and other expenses of the Julia project.
