The Cardano Africa Tech Summit Hackathon ran from November 2025 to January 2026, bringing together participants across 11 teams to build regenerative technology solutions for African communities. The program combined weekly virtual check-ins with two strategic in-person milestone sessions, guiding teams through an action-learning methodology from community research to working prototypes. Virtual sessions ran every Wednesday at 6 PM WAT and every Saturday at 1 PM WAT throughout the hackathon period, covering research methodology, team formation, hypothesis development, build sprint coordination, and presentation preparation. Each session ran 75 to 90 minutes with progress updates, mentor Q&A, and peer learning structured into every call. Two full-day in-person sessions anchored the program. The first, held on November 22 at 4 Ayanboye Street, Anthony, Lagos, focused on idea shaping and validation; teams presented their research findings, received mentor feedback, and sharpened their problem statements into viable concepts. The second, held on December 19 at Cafe One Yaba, was the Demo and Hacking Day, live team presentations, community showcase, and the celebration of solutions built around the Regenerative Principle. Continental evaluation followed in January 2026, with selected teams progressing beyond the Lagos cohort. Three products shipped from the hackathon: AgriDatum, a data intelligence platform for smallholder farmers; TechKR, a reputation layer for technical contributors; and Catalyst, a decentralized financial inclusion platform for Nigerian MSMEs built on Cardano, now continuing development under the name Sovela.
