Learn about our mission
For the sake of discovery
Projects at Building 21 are pursued for the sake of discovery. There are no credits, no grades, no evaluations. Only the pursuit of knowledge.
A safe haven for ideas
We give scholars no-strings-attached resources to facilitate their exploration. Scholars collaborate to advance the most unconventional ideas.
A community of explorers
We run cohort-based programs that connect the most curious seekers to a tight-knit community.
