Michel Krieger (born March 4, 1986) is a Brazilian-American entrepreneur and software engineer who co-founded Instagram along with Kevin Systrom, and served as its CTO. Under Krieger as CTO, Instagram expanded from a few million users to 1 billion monthly active users.[2]

On September 24, 2018, it was announced that Krieger and Systrom were resigning from Instagram.

Life and career[edit]

Krieger was born in São Paulo, Brazil, and moved to California in 2004 to attend Stanford University.[3] At Stanford, where he studied symbolic systems, he met Kevin Systrom.[4] The two co-founded Instagram in 2010.[5] Krieger and Systrom had the idea of building a check-in app, before they made it exclusive for pictures. During the early days, most of the engineering and user experience were developed solely by Krieger. One of the stories related to Instagram’s early days that Krieger recalled is:

One time I woke up and there was an email saying that the site went down, and I was like, who fixed it? Shane, did you fix it? Kev, did you fix it? No. And eventually on the terminal, you press up and you get to see what was the last thing you typed. So, apparently, at 3:30 in the morning I somehow managed to, in a completely drunken state, revive Instagram. That’s how much we were struggling in those days.[6]

After Instagram was acquired by Facebook, Krieger was committed to building and growing Instagram independently. As the user base expanded, Krieger ensured that the platform gives small businesses opportunities to thrive, and that it remains a safe place for teenagers.[7][8]

On April 18, 2020, Krieger teamed up with Systrom again to launch Rt.live, their first product together since leaving Facebook. Rt.live is an up-to-date tracker of how fast COVID-19 is spreading in each US state.[9]


In April 2015, Krieger announced a partnership with charity evaluator GiveWell, committing US$750,000 over the next two years. The funds are to support operations, with 90% allocated to grants identified and recommended through the Open Philanthropy Project process.[10]
