Open source at Two Sigma

We’re committed to sustaining digital infrastructure for the public good – and that manifests in both building our own projects and building on the work of others.

Open source is integral to our culture

Our community of scientists understands the role that open source can have on innovation.

Getting together

We value unique perspectives, and our developers regularly come together at company-sponsored Hack Days and Meetups.

Sharing our ideas

We are learners and teachers, our engineers present project findings and new developments at major conferences.

Supporting the community

We believe in collaboration, and our connection to the open source community is important to us. We are a Gold Sponsor of NumFOCUS and our employees sit on the boards of several major projects.
