Datathon 2026 | 2.º place, Hey Banco Challenge

I earned 2nd place in the Hey Banco Challenge at the 2026 Datathon organized by Tec's Data Science Club, together with Roberto Iván Estrada Hernández, Carol Jatziry Rendon Guerrero, and Eydan Vladimir Peña Ulloa. We identified that most conversations with HAVI, Hey Banco's assistant, ended after a single message, because it was hidden behind a button, responded only when prompted, and lacked context about what users were viewing. In response, we built HAVI 360, a proactive chatbot featuring screen awareness to offer context-specific guidance, a Customer 360 profile that uses NLP to unify profiles, conversations, and transactions and to identify three customer archetypes in real time with tailored communication, and a Next Best Action engine that recommends the right action at the right moment. It also offers direct voice or text navigation that takes users straight to features such as transfers, along with gamification through interactive pets matched to each archetype, making finance feel relational rather than transactional. Beyond its projected ROI, our solution stood out for its solid data foundation, defensible competitive moat, and auditable AI.
