Mike Krieger is a Brazilian-American software engineer and product executive who co-founded Instagram with Kevin Systrom in 2010 and now works at the AI safety company Anthropic. He served as Instagram's chief technology officer from its 2010 launch until 2018, joined Anthropic in May 2024 as its first chief product officer, and in January 2026 stepped out of that role to co-lead Anthropic's product incubator, Labs, alongside company co-founder Ben Mann.[1][2][3]
Krieger (born Michel Krieger on March 4, 1986) is best known for building Instagram into a service that surpassed one billion users before Facebook acquired it for about $1 billion in 2012. At Anthropic he has overseen products built on the Claude family of large language models, including Claude Code and the Model Context Protocol.[1][2]

Mike Krieger is a Brazilian-American software engineer, entrepreneur, and product leader who co-founded Instagram in 2010 and is, as of 2026, a co-lead of Anthropic Labs. Over roughly a decade and a half he moved from building one of the world's largest consumer social networks to building products on top of frontier artificial intelligence, a transition that ran through his own AI-powered news startup, Artifact.[1][3]
Krieger was born on March 4, 1986, in Sao Paulo, Brazil, and grew up there before relocating to California in 2004 to attend Stanford University.[3] At Stanford he studied symbolic systems, an interdisciplinary program that blends computer science, linguistics, philosophy, and cognitive psychology, and he earned both a Bachelor of Science and a Master of Science in the field.[3] It was at Stanford that he met Kevin Systrom, a fellow student who would later become his business partner.
While studying, Krieger interned and worked as a user-experience and engineering hire at the microblogging startup Meebo, experience that sharpened his interest in building consumer software at scale.[3] His symbolic-systems training, which sat at the intersection of human cognition and machine reasoning, would later inform both his product work and his interest in artificial intelligence.
In 2010 Krieger joined Systrom to work on Burbn, a location-based check-in application that allowed users to share their whereabouts, make plans, and post photos. The pair concluded that the app was overloaded with features, and they stripped it down to focus on a single behavior that users enjoyed most: sharing photographs with filters. The reworked product launched as Instagram on Apple's App Store on October 6, 2010. It reached about 25,000 users on its first day and roughly one million registered users within two months.[3][8]
As co-founder and chief technology officer, Krieger led Instagram's engineering and was responsible for keeping the rapidly growing service running. The platform's popularity strained its infrastructure repeatedly, and Krieger became known for re-architecting the back end to cope with surging demand. In April 2012, Facebook agreed to acquire Instagram for a deal widely reported at approximately $1 billion in cash and stock, a landmark transaction given that the company then had only about a dozen employees.[3][4]
Under Facebook's ownership, Krieger continued to oversee engineering as Instagram grew from a few million users into one of the world's largest social networks. By the time of his departure the service had surpassed one billion monthly active users, and Krieger had built its engineering organization to more than 450 people.[1] On September 24, 2018, Krieger and Systrom announced that they were resigning from the company, amid reports of tension with Facebook leadership over Instagram's direction and independence. They left shortly afterward, ending an eight-year run at the company they had founded.[3]
After leaving Instagram, Krieger spent time investing in and advising startups, and in April 2020 he reunited with Systrom to build Rt.live, a tool that tracked the real-time reproduction rate of COVID-19 across U.S. states during the pandemic.[3] The project was a public-service effort rather than a commercial venture.
In 2022 the two founders reunited again to start a new company, Nokto, Inc., and began work on Artifact, a personalized news application that used machine learning to recommend articles to readers. Artifact launched publicly on January 31, 2023, on the App Store and Google Play, and it was sometimes described as a "TikTok for text" because of its algorithmic, interest-driven feed.[5][6] Despite favorable early reviews, the app struggled to reach the scale its founders wanted. In January 2024 Systrom and Krieger announced that they would wind Artifact down, citing a market opportunity that was not large enough to justify continued investment.[6]
Rather than shutter the underlying technology entirely, the founders sold the company. In April 2024, Yahoo announced that it had acquired Artifact, with the deal having closed on March 29, 2024. Yahoo said it would retire the standalone app and fold Artifact's personalization technology into its own products, including the Yahoo News app, while Systrom and Krieger advised during the transition.[5][6] The Artifact experience, building a consumer product centered on machine-learning recommendations, became a direct bridge to Krieger's next role in artificial intelligence.
On May 15, 2024, Anthropic announced that Krieger would join as its first chief product officer, overseeing product engineering, product management, and product design.[1] In announcing the hire, chief executive Dario Amodei described Krieger as "a world-class engineer, builder, and leader," and Krieger said he had "long admired Anthropic's relentless focus on building capable and trustworthy AI systems that empower humans and expand what's possible with technology."[1] At the time, Anthropic was racing to turn its Claude models into polished products for both consumers and enterprises, and Krieger's track record of scaling Instagram and building Artifact made him a natural fit for that mandate.[4]
As CPO, Krieger reshaped how Anthropic built products. He has described embedding product teams closely with research, working on post-training and fine-tuning rather than simply wrapping interfaces around off-the-shelf models, and leaning into Anthropic's strengths in coding and agentic behavior.[7] During his tenure the company shipped a steady stream of releases, including Claude 3.7 Sonnet in February 2025, which introduced user-adjustable reasoning, along with expanded Claude desktop and mobile applications.[7]
Two products from Krieger's era proved especially significant. Claude Code, a command-line tool that lets developers delegate software engineering tasks to Claude, grew from a research preview into a business with a roughly $1 billion annual run-rate within about six months.[2][7] The other was the Model Context Protocol (MCP), an open standard introduced by Anthropic in late 2024 for connecting AI models to external tools and data sources. MCP was widely adopted across the industry and reached on the order of 100 million monthly downloads, becoming one of the fastest-spreading standards in the field.[2][7]
As of 2026, Krieger's primary role at Anthropic is co-leading the company's product incubator, Labs, alongside Ben Mann. Many of Anthropic's most successful products grew out of a small internal incubator that Mann started around the middle of 2024 with just a couple of people. The team operated by quickly building rough prototypes, testing them with a handful of early users, and scaling the ideas that worked. It is credited with helping produce Claude Code, MCP, and later features such as Skills, Claude in Chrome, and Cowork.[2]
On January 13, 2026, Anthropic announced that it was formally expanding this incubator under the name Labs and reorganizing its leadership. Krieger stepped down as chief product officer to co-lead Labs alongside Ben Mann, reporting to president Daniela Amodei; several reports described the move as a return to hands-on building, with Krieger taking a member-of-technical-staff role.[2] Ami Vora, who had joined Anthropic in late 2025, took over as head of product, working with chief technology officer Rahul Patil to scale Claude across consumer and enterprise markets.[2] Anthropic said Labs would roughly double its headcount over the following six months as it pursued early-stage product bets freed from the constraints of the core product roadmap. Daniela Amodei framed the change by saying that "the speed of advancement in AI demands a different approach to how we build, how we organize, and where we focus," and that "Labs gives us room to break the mold and explore."[2]
Krieger's work on Instagram brought him early industry recognition, including a place on lists of leading young entrepreneurs in consumer technology.[3] His share of the Instagram sale and his subsequent investments made him wealthy, with estimates of his net worth ranging into the hundreds of millions of dollars, though such figures are unofficial and vary by source.[3]
Beyond his operating roles, Krieger has been an active angel investor and startup adviser. In July 2025 he joined the board of directors of the design-software company Figma, a position he held until resigning effective April 14, 2026; Figma stated that his departure was not the result of any disagreement over the company's operations, policies, or practices.[3][9] He has also supported philanthropic and cultural causes, including a multi-year commitment to the charity evaluator GiveWell and support for the Institute of Contemporary Art San Francisco.[3]
Krieger married Kaitlyn Trigger in 2015 and is based in the San Francisco Bay Area.[3] He remains a visible voice in technology and product circles, speaking and writing about how artificial intelligence is reshaping the way software is designed and built.[7]
