A closer look
Barber covers Son's family background and the discrimination he faced in Japan, which fueled his ambition.
His early SoftBank years focused on software distribution and publishing. He then bought into Yahoo and other internet firms.
The Alibaba investment, made after a short meeting with Jack Ma, became one of the best venture bets ever.
The Vision Fund backed companies like WeWork, which lost heavily. Barber shows how Son keeps betting despite setbacks.
Barber also shows Son's skill at persuasion. He won over founders, bankers and heads of state with grand visions and fast decisions. The same charm that raised huge sums also led to bets with too little checking, a pattern the book returns to often.
