Allegro started building companies before he could legally sign a contract. At 17, he won 1st place in Germany's highest-endowed startup competition for teenagers – and used the prize to co-found his first company together with a mid-sized German publishing group, running the seven-person team through his final years of school while still studying for his Abitur. That early obsession with how companies actually grow followed him into university: enrolled at WHU – one of Europe's top business schools – Allegro spent his final semester living in Berlin to build what would become Brio, returning to campus only for exams.

What he kept seeing inside enterprises was the same pattern, over and over: the best sellers consistently outperformed the rest by multiples, and no amount of learning videos or quizzes ever closed the gap. The companies he talked to weren't short on training budget – they were short on a way to actually develop people effectively at scale. So he built one. Within just a few months of founding Brio (previously Cuinti), Allegro had closed Audi as his first paying customer, followed by Allianz. Now, he's on a mission to make Brio the way the world's best sales teams train – and the reason average ones stop being average.
