On Wednesday, OpenAI CEO Sam Altman announced Simo's new role as CEO of applications. She will report directly to him after transitioning out of her current role at Instacart later this year.
'In her new role, Fidji will focus on enabling our 'traditional' company functions to scale as we enter a next phase of growth,' Altman said in a blog post. 'Fidji brings a rare blend of leadership, product, and operational expertise, and genuine commitment to ensuring our technology benefits everyone.'
Before joining OpenAI's executive team, Simo served as a member of its board of directors. She will now concentrate on scaling the company's 'traditional' functions as it moves into its next phase of growth. Simo's addition signals OpenAI's potential expansion beyond ChatGPT. Previous reports have suggested the company is exploring ventures into social media platforms.
'This organization has the potential of accelerating human potential at a pace never seen before, and I am deeply committed to shaping these applications toward the public good,' Simo said in the blog post.
Here's everything you need to know about Silicon Valley's latest executive.
The 39-year-old is a first-generation high school graduate from the fishing village of Sète in France. As Fast Company previously reported, Simo was named after a perfume worn by her mother, a boutique owner. She graduated from one of France's most prestigious business schools, HEC Paris, and began her career at eBay in 2007.
Prior to Instacart, Simo served as a senior executive at Facebook, working closely with her former mentor Mark Zuckerberg and eventually leading the Facebook app prior to the company's rebrand to Meta. During her tenure there, from 2011 to 2021, she held roles including director of product management and vice president of video, games, and monetization.
In January 2021, Simo became CEO of Maplebear Inc., Instacart's parent company. She went on to lead Instacart's highly anticipated IPO in 2023, which raised $660 million and valued the company at $9.9 billion.
While serving as CEO of Instacart, Simo cofounded the Metrodora Institute after being diagnosed with postural orthostatic tachycardia syndrome and endometriosis. The clinic and research center is dedicated to treating women with neuroimmune axis disorders by collecting data from consenting patients and sharing it with partner research institutions, in hopes of finding a cure. These disorders include conditions in which the immune system attacks the nervous system, such as lupus, Guillain-Barré syndrome, and long COVID.
