Just about six years after Facebook closed its $1 billion purchase of Instagram, both of the company's founders are resigning, according to a report from The New York Times and confirmed by a post on the company's blog. Kevin Systrom and Mike Krieger served as the company's CEO and CTO, respectively, after pivoting the app from a Foursquare-style check-in service called Burbn to focus on photography in 2010. Less than two years after launching an Instagram iOS app, Facebook announced plans to purchase the company. At the time it had around 30 million users and has since grown to over 800 million.

Their departure brings to mind the path taken by the founders of (fellow Facebook acquisition) Whatsapp, Jan Koum and Brian Acton. Acton left a year ago and later tweeted "#deleteFacebook" during revelations over the company's privacy issues, while Jan Koum announced his departure earlier this year, reportedly due to clashes over how to handle user data.

Update: The news has been confirmed in a blog post written by Systrom. There was no indication of any issues as he said that the two are "now ready for our next chapter."
