Who is Fidgi Simo? The Tech leader Shaping OpenAI’s Applications Strategy
Fidji Simo has spent much of her career building technology products that people use in their everyday lives. From her years at Facebook to leading grocery delivery platform Instacart, she has worked across businesses that have changed how people communicate, shop and access services.
In 2025, she took up the position of Applications CEO at OpenAI, embracing the task of rendering AI more productive for both individuals and companies. The choice of OpenAI by her occurred against the backdrop of an ongoing shift in the AI discourse.
Going beyond being able to write texts and answer questions, AI applications were starting to do other things, such as coding and analysis of information. What remained to be done was to make these functions useful for people’s use.
From Facebook to Instacart
Simo has been with Facebook, which is now known as Meta, for almost a decade now, having occupied different leadership positions within its products. Her experience with the video arm of the company has given her insights on how a business can be grown out of a product that involves technology and user behavior.
In 2021, Simo was appointed as the CEO of Instacart. At this time, the company had reached a point where it was playing an essential part in the business of online groceries. It had reached an important stage of business transformation under Simo’s leadership. The company floated its IPO in September 2023.
The experience from the two companies provided her with an idea of how technology can solve basic problems while building businesses based on the changing needs of consumers.
Making AI Useful at Work
At OpenAI, Simo was tasked with helping bring the company’s AI capabilities to a wider audience. As the CEO of Applications, she was operating in a company where the objective of research would be transformed into tangible applications by using AI.
AI applications have far greater potential than simply helping in writing emails or even summarizing a document. There are many tasks such as programming, conducting research, analysis of information and administrative work that AI software would assist in freeing some time.
However, developing such systems into something valuable is not an easy task. Businesses will require AI software that is dependable, secure and easy to integrate in their operations. People will have to understand how to determine whether to rely on the answer provided by the AI system or not.
Simo’s background in consumer technology helped him to face this challenge. To build something that is truly useful means knowing both what technology can do and what people need.
A New Chapter
In July 2026, Simo stepped away from her operational leadership role at OpenAI and moved into a part-time advisory position, marking a change in her responsibilities at the company.
Through her career, she has traversed three major technological fields: social media, e-commerce, and artificial intelligence. All have affected the daily lives of people, but AI is different in that it has the capacity to affect how people work.
It remains to be seen whether the adoption of these tools by businesses will actually lead to any meaningful changes without affecting accuracy and integrity. The career path of Simo is indicative of the overall trend in technology, from developing products to affecting how people work in the future.
