Where Global Leadership Meets Innovation

Since its founding, Call for Code has convened one of the most influential judging panels in technology and social impact—bringing together leaders whose decisions shape industries, institutions, and global priorities.

Our Eminent Judges include individuals who have governed nations, led the United Nations, pioneered scientific breakthroughs, built global enterprises, and advanced humanitarian efforts—alongside influential technologists and cultural figures whose work has impacted millions of lives.

What distinguishes this panel is not only its stature, but its perspective. Judges represent organizations at the center of global decision-making—including the United Nations, leading technology companies, humanitarian institutions, research organizations, and the open-source community—ensuring that each solution is evaluated through both technical rigor and real-world consequence.

Together, they assess innovations addressing the world’s most urgent challenges—from disaster resilience and climate change to public health and human rights—helping identify the solutions most capable of scaling into real-world impact.

Their participation reflects more than credibility; it reflects alignment. This is a group not only evaluating ideas, but helping define which technologies move forward—and why.
