How many users had LinkedIn reached by August 2004?

LinkedIn had reached 1 million users by August 2004.

That milestone came about a year after LinkedIn launched publicly in May 2003. The company was founded in December 2002 by Reid Hoffman and a team that included former PayPal and Socialnet.com colleagues. In its early period, LinkedIn focused on building a professional-identity network rather than chasing the mass-audience model associated with entertainment-oriented social platforms.

The figure is easy to confuse with later milestones. LinkedIn reached 10 million users in April 2007, three years after passing the 1-million mark. It also continued expanding internationally and adding revenue products, including premium subscriptions and recruiter-focused services.

The August 2004 figure refers to users, not employees, paying subscribers, or monthly active users. It is a historical membership milestone recorded in LinkedIn's early company timeline.
