About us

Interstitial formed organically as a collective of technology freelancers looking to combine our skills and work together on projects we believe in. We come from diverse backgrounds - embedded systems, web development, data science and more - but we share in this common goal: to make the world a better place through technology. We work on environmental science, sustainable agriculture, the green economy, and human rights. We are engineers, scientists, designers and architects onboard Spaceship Earth.

Our innovative contracting model allows for substantial flexibility in matching our workforce with the needs of our clients. From hourly consulting to long-term contracts and government grants, Interstitial delivers high-quality engineering solutions for a variety of project structures.

We believe that good ideas deserve to be shared, so we are committed to practicing open-source principles wherever possible. Our developers maintain and contribute to open software and hardware projects that are used around the globe. Check out our GitHub.

We operate democratically as an employee-owned worker cooperative. Our flat and fair structure encourages collaboration at every level, and ensures that everyone is invested in the quality of our work. It also makes Interstitial a great team to be a part of - if you’re a technology professional interested in working toward positive change, please reach out to us!
