how long did it take instagram to reach 1 million users?

Instagram reached 1 million users in less than three months after launch.

Quick Scoop

• Instagram launched on October 6, 2010 as an iPhone-only photo-sharing app.

• By late December 2010, it had already passed the 1 million registered user mark, meaning it hit that milestone in under three months.

• For context, reports note it took Foursquare a bit over a year and Twitter around two years to reach the same 1 million user milestone, which highlights just how fast Instagram grew in its early days.

In startup lore and forum discussions, this “under three months to 1M users” stat is often quoted as a benchmark example of explosive early product- market fit rather than a pace most apps can realistically expect to match.
