Which startup was founded by Mark Zuckerberg?

Mark Zuckerberg founded Facebook, originally launched as TheFacebook in 2004.

Zuckerberg built the first version while attending Harvard, where the site initially served students at the university. His early collaborators and co-founders included Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. The service expanded to other universities before opening more broadly.

The name came from “face books,” student directories containing photographs and basic information. A common mix-up is crediting Zuckerberg as Facebook’s only founder; he was the central creator, but the company recognizes several co-founders. Another distinction is that Facebook is the social-networking service, while Meta Platforms is the parent company that acquired and reorganized the business.
