The fourth edition of the Aleph Hackathon ran from August 29 to 31, 2025, opening the Aleph Festival: 1,300 builders, 320 projects submitted and 25 simultaneous chapters around the world. It was the largest hackathon in Latin America's history.
Federalization was a priority of this edition. The chapters were physical hubs organized by communities and universities, bringing the in-person experience to participants who normally have no access to it: Buenos Aires, La Plata, Rosario, Mar del Plata and Mendoza within the country; Cochabamba, Santa Cruz, Santiago de Chile, Quito and Recife across the region; and Kilifi, Accra and Ikorodu in Africa. Twelve universities brought in their students, some with chapters of their own, and more than 50 local communities helped with outreach, mentoring and organization.
The tracks were organized alongside leading protocols in DeFi, privacy, interoperability and real-world assets, and for the first time there was a dedicated artificial intelligence track. With that opening and the partnerships with universities and projects like dev3pack, the edition set a diversity milestone: 26 nationalities from Latin America and Africa, and 34% women.
Every participant had access to mentors, in tech and also in design, business, community, go-to-market and pitching: more than 70 online mentors from the Crecimiento network and more than 40 in-person mentors at the local hubs.
