Jesper Kampmann Madsen, the founder of London-based tech firm Trace2Trace, is building technology to map the networks behind illegal gambling. Madsen, 35, and born in Denmark, knows what it means to be on the other side of the screen: as his decision to fight illegal gambling stems back to his own addiction, he tells iGB.
