In this capacity, she was instrumental in translating cutting-edge AI research into deployable, real-world applications, gaining invaluable insight into the infrastructure requirements and operational nuances of advanced AI systems. Her departure from OpenAI in July 2026, citing health reasons, was a notable event in the AI community, though she continues to advise the company part-time, maintaining her connection to the forefront of AI innovation.
Prior to her tenure at OpenAI, Simo held the dual role of Chair and CEO of Instacart, where she successfully steered the grocery delivery giant through its 2023 IPO. This experience is particularly relevant for Nscale, as Simo possesses firsthand knowledge of the intricate process of taking a high-growth technology company public, from investor roadshows and regulatory compliance to establishing robust corporate governance and market communication strategies. Her leadership at Instacart demonstrated her capability to manage rapid expansion, diversify revenue streams, and maintain investor confidence in a competitive market.
Simo’s extensive career also includes more than a decade at Meta (formerly Facebook), culminating in her role as head of the Facebook app. During her time there, she was responsible for significant product development and growth initiatives, overseeing a platform used by billions worldwide. This experience instilled in her a deep understanding of what it takes to scale products to an unprecedented global user base and, crucially for Nscale, the immense backend infrastructure required to support such scale. Beyond her operational roles, Simo also contributes her expertise as a board member for Shopify, further broadening her perspective on e-commerce, platform economics, and strategic technology investments.
The Vision Behind Nscale’s "Deliberately Built" Board
Josh Payne, Nscale’s founder and CEO, articulated the strategic significance of Simo’s addition. In a statement, Payne emphasized that Simo is "one of the few leaders who understand what it means to scale products used by billions of people and the demands those products place on the underlying systems." He elaborated, "That’s what we’re building for at Nscale. Fidji joins a board we’ve built deliberately, with the experience of scaling platforms to the largest in the world, and the independence, financial rigor and operating depth to which companies at this scale are held."
Payne’s remarks highlight the meticulous approach Nscale has taken in assembling its board. The presence of Sheryl Sandberg, former COO of Meta, brings unparalleled experience in operational excellence and global business strategy. Susan Decker, a seasoned executive with a background at Yahoo! and various board roles, contributes financial acumen and governance expertise. Nick Clegg, Meta’s President of Global Affairs, offers insights into global regulatory landscapes and public policy, increasingly critical for a company operating at the intersection of advanced technology and national infrastructure. This collective expertise forms a formidable advisory and oversight body, designed to guide Nscale through its rapid growth phase and the scrutiny of public markets. Simo’s unique blend of deep AI operational knowledge, consumer tech scaling, and IPO leadership perfectly complements this existing strength, providing Nscale with a comprehensive strategic advantage.
The Broader AI Infrastructure Landscape and Nscale’s Position
The demand for AI compute capacity has created a new gold rush in the technology sector. Major hyperscale cloud providers—Amazon Web Services, Microsoft Azure, and Google Cloud—are investing tens of billions of dollars annually to expand their AI infrastructure. However, Nscale and similar specialized AI data center providers are carving out a niche by offering tailored solutions that often surpass the capabilities of general-purpose cloud offerings for specific, highly intensive AI workloads. These specialized centers can provide higher density GPU configurations, more efficient cooling mechanisms (like liquid cooling), and direct access to high-bandwidth interconnects crucial for distributed AI training.
The burgeoning market has seen significant capital inflow. Reports from market intelligence firms indicate that investments in AI infrastructure startups and projects globally surged by over 300% in the last two years. This surge is driven by several factors: the increasing complexity of AI models, which require exponentially more compute power; the broadening application of AI across industries from healthcare to finance to manufacturing; and the competitive imperative for companies to integrate AI into their products and services. Nscale’s focus on designing, building, and operating these critical facilities positions it at the heart of this technological transformation. Its U.K. base also provides a strategic entry point into the European market, which is rapidly expanding its AI capabilities and regulatory frameworks.
Nscale’s valuation has indeed skyrocketed, reflecting both its technological promise and the intense market demand. The startup, which was founded in 2024, is reportedly seeking to raise up to $3.5 billion in pre-IPO financing, as first reported by Bloomberg last week, citing unnamed sources familiar with the matter. This substantial funding round, if successful, would provide Nscale with significant capital to accelerate its expansion plans, invest further in R&D, and secure long-term supply chains for critical components like GPUs and specialized networking equipment. A pre-IPO raise of this magnitude would also underscore strong investor confidence in Nscale’s business model and its ability to execute on its ambitious growth strategy. It signals to the market that the company is well-capitalized and ready for the rigors of public trading, aiming for a strong debut later this year.
