What happens when you gather a small team of enthusiasts for a COVID-19 data science competition? What happens when that small team reaches 1000 registrations within 3 weeks? What happens to the tens of thousands of hours of the team's work when the competition ends? Join us as we document and discuss how such a movement is born and how it shuffles, shifts and organises itself into an international powerhouse for positive change for the global medical community. A light-hearted, informative and not-too-technical showcase of the beauty of real human collaboration in the face of a common threat.
