Michel Krieger woke up on a morning in 2010 to find his life's work had crashed, and the only person who could fix it was himself, drunk and alone at 3:30 in the morning. Born in São Paulo, Brazil, on the 4th of March 1986, Krieger moved to California in 2004 to study symbolic systems at Stanford University, a field that combined computer science, philosophy, and linguistics. It was there that he met Kevin Systrom, a fellow student with a vision for a photo-sharing application. Their initial idea was not to share pictures but to build a check-in app, a concept that would eventually pivot to become Instagram. In the early days, Krieger was the sole engineer, handling both the backend infrastructure and the user experience. The struggle was so intense that the platform would frequently go down, and Krieger would often be the one to revive it from a drunken state, typing commands into a terminal to get the site back online. This period of chaotic development laid the foundation for a platform that would eventually reach one billion monthly active users under his technical leadership as chief technology officer.
The Billion User Leap
Under Krieger's direction as chief technology officer, Instagram grew from a few million users to one billion monthly active users, a feat that required scaling infrastructure to handle unprecedented traffic. The acquisition by Facebook in 2012 brought immense resources but also immense pressure to maintain performance while expanding features. Krieger was committed to building and growing Instagram independently, ensuring that the core engineering culture remained intact despite the massive influx of capital and personnel. His technical decisions shaped the platform's evolution, from the introduction of video sharing to the development of Stories, which mimicked the ephemeral nature of Snapchat. The scale of growth was so rapid that it required constant innovation in data handling and server management. Krieger's ability to manage this growth while maintaining the app's speed and reliability was a testament to his engineering prowess. However, the pressure of leading such a massive platform eventually took its toll, leading to his resignation on the 24th of September 2018, after which he left the company to pursue new ventures.The Post-Facebook Era
After leaving Facebook, Krieger and Systrom reunited to launch Rt.live on the 18th of April 2020, a collaborative product designed to track the spread of COVID-19 in each US state. This application served as a real-time dashboard, providing up-to-date information on the pandemic's progression, a critical tool during a time of global uncertainty. The project demonstrated their ability to pivot quickly to address immediate societal needs, leveraging their technical expertise to create a platform that was both informative and accessible. Following this, they launched Artifact, an AI-powered news app, on the 31st of January 2023, which aimed to curate news content using artificial intelligence. However, the app was shut down in January 2024, marking another chapter in their post-Facebook journey. These ventures highlighted Krieger's willingness to experiment with new technologies and address real-world problems, even if the outcomes were not always successful. His work in this period reflected a shift from building consumer apps to exploring the potential of AI and data-driven solutions.
