SAN FRANCISCO — Mark Zuckerberg, the founder and chief executive of the company formerly known as Facebook, called his top lieutenants for the social network to a last-minute meeting in the San Francisco Bay Area this month. On the agenda: a “work-athon” to discuss the road map for improving the main Facebook app, including a revamp that would change how users browse the service.
For weeks beforehand, Mr. Zuckerberg had sent his executives messages about the overhaul, pressing them to increase the velocity and execution of their work, people with knowledge of the matter said. Some executives — who had to read a 122-page slide deck about the changes — were beginning to sweat at the unusual level of intensity, they said.
Facebook’s leaders flew in from around the world for the summit, the people said, and Mr. Zuckerberg and the group pored over each slide. Within days, the team unveiled an update to the Facebook app to better compete with a top rival, TikTok.
