Our Work

Our work has three themes, reflecting the three key aspects of our mission: verifiable, systems, and organizations.

Verifiable

We make formal verification technology more accessible by developing tools and processes to improve the quality and experience of software engineering. We believe that accessible specification languages, powerful solvers, and toolkits for integrating with modern software can transform our ability to build and maintain critical, trusted systems.

Systems

We are a core developer of the Cosmos Network, where we focus on sovereign, interoperable technologies for more sustainable communities. We believe that system scaling is as much a social problem as it is a technical one, and that fixing the exploitative monetization of the internet may require a renewed understanding of money itself.

Organizations

We are structured as a worker cooperative, organized around a collaborative web of workflows. We believe in a more sustainable form of technological organization that nurtures its employees and improves its society.
