Our founding team

2i2c is founded by leaders in the research, education, and open source community. We have years of experience in deploying infrastructure for interactive computing, as well as integrating that infrastructure into institutional pedagogy and research efforts. In addition, we are core contributors to many large open source projects in the Jupyter community.

Our story

We created 2i2c in order to make interactive computing more accessible, powerful, and transformational for research and education.

2i2c’s founding team has years of experience in running interactive computing infrastructure for research and education. We have also developed and contributed to a number of tutorials and workshops so that other organizations could deploy this infrastructure for themselves (for examples, see the Zero to JupyterHub guide as well as the Littlest JupyterHub guide).

Over time, we learned that deploying, customizing, and maintaining infrastructure was a significant barrier to institutions that would otherwise benefit from it. Documentation and training was helpful, but requiring each organization to hire its own dev-ops architect was a non-starter. This was particularly true for under-resourced institutions such as community and state colleges. These organizations often turned to vendors that offered proprietary infrastructure products that encouraged lock-in, reduced flexibility and choice, and did not directly support open source communities.

2i2c is our attempt to ensure that organizations in research and education have access to interactive computing infrastructure that is 100% open source and community-driven, that is easy to access and procure, that requires minimal expertise to customize and run, that gives organizations full control over their infrastructure, and that offers the best interactive computing experience for the workflows of our community.

Our Experience

2i2c has worked on projects in interactive computing infrastructure for several years now. Its team members are core contributors or project leads on the following services and tools:

Jupyter at Berkeley

The DataHubs at UC Berkeley are a collection of JupyterHubs used across the university’s data science courses. These hubs serve thousands of students across a variety of courses. 2i2c’s team has helped build and maintain these hubs, and also assists the university in integrating pedagogical content with the datahubs and other Jupyter infrastructure.


The Pangeo project is a community platform for Big Data geoscience. It runs several JupyterHubs and BinderHubs for geoscience communities, and is a pioneer in integrating open source technology and standards with cloud infrastructure to facilitate access and computation with extremely large datasets.

Project Jupyter

In addition to the services above, many 2i2c members have spent several years as core Jupyter Project maintainers. They have used their experiences in research and education to improve core tools in infrastructure with JupyterHub, interfaces for learning and research with the Jupyter Notebook and Jupyter Lab, and tools for scholarship such as Jupyter Book.


The Syzygy service provides interactive computing environments to more than 30 institutions across Canada. It is based out of the Pacific Institute for Mathematical Sciences (PIMS). Syzygy runs JupyterHubs for thousands of users across a variety of research and education use-cases.


Callysto is a free, interactive, curriculum-based learning and skills development tool — think “interactive textbook” — that can be accessed from any device with an internet connection. It was created by Cybera and PIMS to help students strengthen their computational thinking, coding, and data science skills. Callysto builds open education resources and training programs for teachers and students in grades 5-12 that leverage a cloud-hosted interactive computing platform.


Mybinder.org is a massively-open free service for reproducible, sharable interactive computing environments. It serves over 100,000 users each week, and has been one of the driving services behind improvements to JupyterHub on Kubernetes and the reproducible environments tool, repo2docker.
