OpenAI has announced a significant leadership change with the appointment of Fidji Simo as the head of its applications business. Simo, who has been serving as the CEO of Instacart, will now take on the role of CEO of Applications at OpenAI, reporting directly to the company's CEO, Sam Altman. This move was detailed in a memo to employees, which OpenAI also shared on its blog. Altman emphasized that Simo's new position will involve overseeing existing business and operational teams, ensuring that OpenAI's research translates effectively into real-world benefits. Her focus will be on scaling these traditional company functions as OpenAI enters a new phase of growth. This leadership update follows closely on the heels of OpenAI's recent structural changes. Earlier, the company declared that its nonprofit arm would maintain control, even as it transitions into a public benefit corporation. This restructuring comes amid external pressures from civic leaders and former employees. OpenAI, originally founded in 2015 as a research lab, has been navigating a complex landscape, including a legal dispute with co-founder Elon Musk, who now leads a competing generative AI firm, xAI. Fidji Simo is no stranger to steering companies through transformation. Recognized as one of CNBC's Changemakers in 2024, she played a pivotal role in taking Instacart public the previous year, a milestone that marked the end of a prolonged tech IPO drought. Instacart, which experienced significant growth during the Covid pandemic due to increased demand for home grocery delivery, has managed to sustain and build on its pandemic-era gains under Simo's leadership. She expressed to CNBC that Instacart has not only maintained its success but also achieved sustainable and profitable growth, dispelling doubts about its post-pandemic viability. Before her tenure at Instacart, Simo was a prominent figure at Facebook, now Meta, where she served as the head of Facebook from 2019 until 2021. Her impressive career trajectory includes being one of the highest-ranking female executives at the company, following in the ranks of Sheryl Sandberg and Marne Levine. Originally from France, Simo has built a reputation for her leadership and strategic vision. In a recent post on the social media platform X, Simo expressed her gratitude towards the Instacart team for the journey they shared. She plans to remain CEO of Instacart for a few more months to facilitate a smooth transition, after which she will continue as the company's chair. Instacart, meanwhile, has announced plans to unveil Simo's successor soon, indicating that the new leader will be chosen from its pool of talented senior executives. In a recent development, Instacart also launched "Fizz," a new app dedicated to delivering drinks and snacks to an adult audience. Sam Altman, in his memo, also outlined his future focus areas at OpenAI, which will include research, compute, and safety systems. Earlier in March, OpenAI had announced that operating chief Brad Lightcap would expand his role to encompass the company's business and daily operations. This adjustment allows Altman to concentrate more on research and product development. Lightcap's responsibilities now include global deployment, strategy, partnerships, and infrastructure. OpenAI's journey has been financially backed by Microsoft and recently it was valued at $300 billion in a funding round spearheaded by SoftBank. This robust financial endorsement underscores the company's influential position in the tech landscape. This article also included a correction noting a previous misspelling of Simo's first name in the headline. Additionally, CNBC's Salvador Rodriguez contributed to the report.
