We contribute to the Nix, Bazel and Haskell ecosystems building tools and solving problems alongside their communities. This give us the expertise to help organizations adopt these technologies and use them effectively at scale.
Build reproducible development and deployment environments across teams and infrastructure. We contribute to Nix itself and its surrounding tooling, giving us the depth to solve problems from adoption through large-scale production use.

We were among the first to adopt Bazel shortly after its launch from Google. We have contributed key features and programming language support to Bazel to enable the industrial scale needs of our clients.

Build correct, maintainable software for domains where reliability matters. Our engineers contribute across the Haskell ecosystem, from compiler and language tooling to libraries and production systems.
