Nscale Adds Former OpenAI Exec Fidji Simo to Board Ahead of IPO

Nscale, the rapidly growing U.K.-based AI data center startup, has announced the appointment of Fidji Simo, a former top executive at OpenAI, Meta, and Instacart, to its board of directors. This strategic move comes as Nscale prepares for an anticipated initial public offering (IPO) later this fall, signaling a significant strengthening of its leadership as it eyes public markets.

Simo's addition to Nscale's board is particularly noteworthy given her distinguished career. She recently served as the CEO of AGI deployment at OpenAI, effectively holding the No. 2 executive position at the prominent AI research lab until her departure in July 2026 due to health reasons. Despite stepping down from her full-time role, Simo continues to advise OpenAI on a part-time basis, demonstrating her ongoing influence in the AI sector.

Prior to her tenure at OpenAI, Simo made a profound impact at Instacart, where she held the roles of chair and CEO. She successfully navigated the grocery delivery giant through its public offering in 2023, a critical experience that will be invaluable to Nscale. Her extensive background also includes more than a decade at Meta, where she notably led the Facebook app. Simo also currently serves on Shopify’s board, further underscoring her broad expertise across diverse technology platforms.

Nscale’s founder and CEO, Josh Payne, emphasized the strategic importance of Simo’s appointment. Payne highlighted Simo as one of the few leaders with a deep understanding of what it entails to scale products used by billions of people and the immense demands these products place on underlying infrastructure systems. "That’s what we’re building for at Nscale," Payne stated, adding that Simo joins a board deliberately constructed with leaders experienced in scaling platforms to global prominence, coupled with the independence, financial rigor, and operational depth required for companies of this scale.

The startup's board already boasts an impressive roster of high-profile tech executives, including Sheryl Sandberg, Susan Decker, and Nick Clegg, reflecting Nscale's ambition and investor confidence. The inclusion of Simo further bolsters this formidable group, bringing specific IPO leadership and AI scaling expertise.

Founded just two years ago, Nscale has witnessed its valuation soar, driven by the explosive demand for artificial intelligence infrastructure. The company specializes in designing, constructing, and operating state-of-the-art AI data centers, a critical component in the ongoing AI boom. Last week, Bloomberg reported that Nscale is actively seeking to raise up to $3.5 billion in pre-IPO financing, citing anonymous sources familiar with the matter. This substantial fundraising target underscores the immense market interest and high expectations surrounding the U.K.-based company.

Simo's proven track record of steering a major tech company through a successful IPO, combined with her deep insights into the operational requirements of large-scale AI deployment, positions her as a pivotal asset for Nscale. Her leadership is expected to provide critical guidance as the startup navigates the complexities of going public and continues its aggressive expansion in the booming AI infrastructure market. The appointment signals Nscale's commitment to robust governance and strategic leadership as it transitions from a high-growth startup to a publicly traded entity.
