Alexandr Wang on the Unexpected Communication Habit of Mark Zuckerberg

Wang, who founded the AI training startup Scale AI, admitted he was initially confused by the time Zuckerberg invested in their correspondence. After observing the CEO’s workflow, he realized that Zuckerberg had mastered the ability to write with precision and speed, effectively balancing his massive workload while maintaining a focus on critical priorities. This capacity for rapid, high-quality communication, Wang noted, allows the Meta leader to manage the intense demands of his position while protecting time for his family and personal life.

The professional relationship between the two grew from occasional consultations into a major corporate alliance. After an introduction by Meta executive Alex Schultz, their contact deepened as Zuckerberg sought to accelerate Meta’s AI development. By June 2025, the collaboration culminated in Meta investing $14.3 billion for a 49% stake in Scale AI, bringing Wang into the fold to lead Meta’s superintelligence efforts. Wang credits Zuckerberg’s continued success to a rare combination of technical focus and the humility to actively seek advice from other entrepreneurs, despite his two decades at the helm of a global tech giant.
