Czech Association for Effective Altruism (CZEA)

The Czech Association for Effective Altruism (CZEA), legally registered as Spolek pro efektivní altruismus (z.s.), is the national effective altruism organization for the Czech Republic. It was founded in the second half of 2016 by members of the local LessWrong community, with support from Czech EA figures at Oxford and Harvard. The organization's inaugural project was hosting EAGx Prague 2016, which drew over 100 participants and catalyzed growth from roughly 5 to 15 members. CZEA is based in Prague and also maintains a secondary hub in Brno. Its membership has grown to over 50 people, primarily early- and mid-career professionals. The organization has historically operated with a small paid staff of 2-3 full-time equivalents, funded primarily through a Community Building Grant from the Centre for Effective Altruism, supplemented by project grants from the Long-Term Future Fund and EA Infrastructure Fund. CZEA's core activities include educational seminars on EA principles, AI safety, and high-impact careers; regular community meetups and events; and the incubation of independent projects. Notable projects affiliated with or launched by CZEA include: the Human-Aligned AI Summer School (HAAISS), AI Safety Camp, AI Safety Research Program, Effective Thesis (supporting students in pursuing world-changing research), CFAR workshops in Europe, the Epistea Space community venue in Prague, Czech Priorities (a policy think tank), Confido (digital tools for probability communication), and the Alignment of Complex Systems Research Group at Charles University. In December 2020, CZEA also organized EAGx Prague 2022, a major EA conference. The organization has positioned Prague as a cost-effective hub for Central and Eastern European EA activity, emphasizing that relatively low costs of living make research and events cheaper to run than in Western Europe or the US. As of early 2026, CZEA is undergoing a significant organizational transition. After failing to renew the grant that funded its paid community building team, the board decided the most responsible path forward was to become a volunteer-run organization. The paid staff are disbanding, and the organization is recruiting community members to take ownership of events, programs, and communications going forward. The transition began at the start of 2026.
