More About Us

With a network of partners in technology, academia, social impact and the arts, Unfinished is imagining the future of technology, culture, and our economy to create a thriving multiracial democracy.

Project Liberty seeks to accelerate the world’s transition to an open, inclusive data economy that puts citizens in control. At the core is a shift from centralized to decentralized—a future in which all people, not just the few, directly benefit from their participation and contribution. The success of this work, in fact, depends on many people and organizations actively working together to shape a better future.

The determined team behind the earliest stages of Project Liberty is working to pave the way for these many contributors by actively engaging diverse voices, and equipping them with the critical infrastructure they need to catalyze change. We have developed the technology to make a shared, community governed social network possible—now available to the public as open source code. We are designing developer tools and an incentive system to reward early adopters and their work, and to support migration to a healthier web economy. And we are bringing together networks of organizations that seek change—including the formation of an Institute with Georgetown University and Sciences Po focused on leveraging technology to drive the common good.

We believe having diversity of perspective, professional backgrounds, identity groups and lived experience is a strength for teams and we actively encourage candidates of all backgrounds to apply. Unfinished is proud to be an equal opportunity employer.
