As of December 2014, Instagram has over 300 million action users according to cnbc.com intagram is now bigger than twitter
Instagram has hit a major milestone. The company now has more than 300 million monthly active users, sharing more than 70 million photos every day, and an average of 2.5 billion daily “likes.”That 300 million number is meaningful for a couple of reasons.
First, it’s impressive growth. Since March, the number of new monthly active users has totaled more than 100 million.Second, this now makes the photo-sharing app, which Facebookbought for $1 billion in April 2012, bigger than Twitter, which has 284 million monthly active users, and whose market cap is around $23 billion.
The man behind is no other than Kevin Systrom (born December 30, 1983) is an American entrepreneur and software engineer, best known as the co‑founder and CEO of Instagram, an online mobile photo, video sharing application and social networking service for iPhone and Android that allow users to apply a filter to a photo and share it on the service or on other social networks like Facebook, Twitter, Tumblr, and Flickr. In 2013, Systrom was listed in theForbes 30 under 30 list under the Social/Mobile category. Together with Mike Krieger, Systrom launched Instagram in San Francisco on October 6, 2010. Instagram is one of the fastest growing services of all time, hitting 80M users by July 26, 2012 and it was acquired by Facebook for $1B less than 2 years after its launch.”Our goal is to not just be a photo-sharing app, but to be the way you share your life when you’re on the go,” Systrom says.
