About flox

Our story

flox was born of our team's experience in deploying Nix tooling in enterprise and our difficulties with the state of developer tooling today. We built flox to deliver the developer experience and battle-tested architecture your systems deserve.

flox first began as a project to deploy Nix at scale at The D. E. Shaw Group and quickly grew to be one of the largest deployments of Nix ever seen in an enterprise setting. Our team includes a mix of new and long-established leaders in the Nix community and we dedicate significant time and resources to contribute back to the Nix ecosystem in important ways.

flox is backed by amazing investors focused on open-source such as NEA, Hetz Ventures, Addition Ventures, and angels such as Thomas Dohmke (GitHub CEO), Guy Podjarny (Snyk founder), and James Turnbull (former VP Docker, CTO Sotheby's).

Our Commitment to Nix and Open Source

The future is Nix-native and we are not just betting on it: Nix is in our DNA. As an explicit part of our culture, we will continue to support Nix, the many amazing tools that are and will be built on it and the community through direct contributions to the NixOS Foundation, open source, sponsorships, evangelizing and organizing events.

One of our key goals is growing Nix itself: flox will always provide seamless compatibility in and out of Nix. Our efforts center on onboarding more developers onto Nix via flox, providing a happy path for them to grow into the wider Nix ecosystem.

Finally, we want to thank everyone who has contributed to making the Nix vision a reality. We truly stand on the shoulders of giants, and feel grateful to be able to contribute to this amazing project.
