About Topos Institute

Topos Institute is a mission‑driven, donor‑facing 501(c)(3) research institute based in Berkeley, California that develops socio‑technical tools and research to improve collective sense‑making and cooperative decision‑making. The organization focuses on interdisciplinary work spanning mathematics (including category theory), programming language theory, software systems, and philosophy and ethics of technology. In the most recent fiscal years Topos has expanded funded research activity and institutional capacity: it received a majority portion of its support from federal research grants in FY2024, completed audited financial statements with an unqualified auditor’s opinion, and established a UK operating subsidiary to support international work. Topos also runs a Summer Research Program and other community initiatives that support early‑career researchers and produce open research outputs.

Summer Research Program with tangible outputs
