How Mike Krieger Co-Founded Instagram
His Role as Instagram’s CTO
Krieger co-founded Instagram with Kevin Systrom in 2010 and served as the company’s Chief Technology Officer . In this role, he was responsible for the engineering and technical side of the app, focusing on building features that made it easy and enjoyable for people to share photos. Under his leadership, Instagram grew from a small startup to a platform with hundreds of millions of users.
His background in symbolic systems gave him a unique perspective on product development. He was as interested in how people experienced the app as he was in the engineering that made it function. This combination of technical skill and user empathy helped Instagram become not just functional but deeply engaging for its users.
As CTO, Krieger was the technical force behind Instagram’s rise from a startup to a global platform.
Facebook Acquisition and His Departure
Facebook acquired Instagram in 2012 for $1 billion in cash and stock, a deal that made Krieger and Systrom very wealthy . The two founders stayed on to continue running Instagram, and Krieger helped push the product forward. However, over time, tensions grew between them and Facebook’s leadership over the direction of the product.
In September 2018, both Krieger and Systrom announced they were leaving the company to “explore creativity again” . Their departure marked the end of an era for Instagram, which had become one of the most successful acquisitions in tech history. Krieger left with a reputation as a builder who had helped create something that changed how people communicate and share their lives.
The Facebook acquisition made Instagram a giant, but Krieger eventually chose to leave and pursue new creative challenges.
Mike Krieger’s Career After Instagram
Building the Artifact News App
After leaving Instagram, Krieger and Systrom teamed up again to launch Artifact, an AI-powered news app, in 2023. The app was designed to give users a personalized feed of news articles, using artificial intelligence to learn what they were interested in. It was described as something like a personalized news discovery tool, and it received attention for its innovative approach to how people consume news.
Despite the buzz around its launch, Artifact struggled to gain a large enough user base to justify continued investment. Krieger and Systrom made the decision to shut it down in 2024. The experience showed that even successful founders do not always hit the mark with every new product, and it highlighted the challenges of building something new in a crowded market.
Artifact was an ambitious attempt to rethink news consumption, but the founders chose to shut it down when the numbers did not support continuing.
His Work at Anthropic Labs
In 2024, Krieger joined Anthropic, an artificial intelligence company, as its Chief Product Officer. In this role, he oversaw product development as the company worked to scale its AI assistant, Claude, for both enterprise and consumer markets. In January 2026, Krieger transitioned to co-lead Anthropic’s internal Labs team.
Labs is Anthropic’s experimental products incubator, focused on building early-stage AI products rather than scaling existing ones. This move put him back in a smaller, more exploratory unit, the same operating mode where he has historically done his best work. He has spoken about the importance of curiosity and creativity in navigating the AI era, emphasizing that human skills like relationships and the ability to organize people will remain valuable.
Krieger’s current work at Anthropic Labs focuses on experimenting with new AI products and pushing the boundaries of what artificial intelligence can do for everyday users.
