The whole story in five minutes — the man, the milestones, and how this reference is organized.
Who he is
Mark Zuckerberg (born 14 May 1984) is the co-founder and CEO of Meta Platforms, Inc. In February 2004, from his Harvard dorm room, he launched thefacebook — a campus social network that grew into Facebook, then into a family of apps (Facebook, Instagram, WhatsApp, Messenger) used by more than 3 billion people daily. In October 2021 he rebranded the company as Meta to signal a long-term bet on the metaverse and virtual reality.

The big ideas in his own words
Three recurring themes run through his public statements:
- Connectivity — making the world more open and connected, from the original Facebook mission to Internet.org.
- Moving fast — iteration speed as strategy; mistakes fixed in production.
- The next platform — first social, then mobile, then VR/AR and AI: each era is a bet that the interface will change.
Read them in key ideas, in his own words.
