- The company's board also includes Sheryl Sandberg, Susan Decker and Nick Clegg, assembled to bring scaled platform experience and public company discipline.
Nscale, a United Kingdom-based startup that designs, builds and manages data centers optimized for artificial intelligence workloads, has added Fidji Simo to its board. The appointment comes as the company pursues a $3.5 billion fundraise ahead of a planned IPO this fall, signaling preparation for the operational and governance complexity of scaled public operations.
Fidji Simo’s executive background
Simo has held leadership positions at three major technology organizations, each representing a different stage of company maturity and market focus.
Her recent departure from OpenAI
Simo served as CEO of AGI Deployment at OpenAI, making her the company’s second-ranking executive. She departed in July, publicly citing health reasons, though she continues to advise the company part-time. Her departure occurred during a period of significant attention on OpenAI’s organizational structure and strategic direction.
Over a decade at Meta
Prior to OpenAI, Simo accumulated more than ten years at Meta, eventually becoming head of the Facebook application. That tenure placed her at the center of one of the world’s largest social networks and exposed her directly to the infrastructure challenges of serving billions of users.
Instacart leadership and IPO experience
Simo served as chair and CEO of Instacart, the grocery delivery service, and directed the company through its 2023 initial public offering. This experience makes her one of relatively few executives with direct knowledge of taking a major technology business from private to public status in recent years.
Board additions ahead of public markets
Simo’s appointment adds her to a board that already includes Sheryl Sandberg, Susan Decker and Nick Clegg. Founder and CEO Josh Payne stated in announcing the addition that the board had been deliberately constructed to bring together leaders with experience scaling platforms to the world’s largest reaches, combined with the financial independence, rigor and operational depth required of major public companies.
Payne specifically noted that Simo exemplified leaders who grasp the demands of scaling products to billions while understanding the computational infrastructure such scale requires. He characterized her addition as central to Nscale’s mission.
Valuation acceleration and funding strategy
Founded two years ago, Nscale has experienced rapid valuation growth driven by corporate demand for data center capacity built explicitly for artificial intelligence. The startup’s core business is constructing and operating these specialized facilities.
Nscale is reportedly targeting a fundraise of up to $3.5 billion before its fall IPO, according to Bloomberg sources. The magnitude of the target reflects both the capital intensity of data center operations and investor confidence in businesses providing infrastructure for artificial intelligence deployment and training.
Why data center infrastructure has become central
The surge in demand for AI data centers reflects fundamental constraints in the technology infrastructure market. Companies developing and deploying large-scale AI models require substantial computational capacity. In 2024 through 2026, available infrastructure has become a bottleneck limiting AI adoption across enterprises and research institutions.
Nscale’s positioning as a builder and operator of AI-specialized data centers, combined with a board assembled to navigate operations at public company scale, reflects how central this infrastructure category has become to enterprise technology strategy and capital markets attention.
Simo’s broader board engagement
In addition to her appointment to Nscale, Simo holds a seat on Shopify’s board, indicating that multiple major platform companies are drawing on her expertise in governance and scaled operations. Her simultaneous involvement with multiple large technology organizations suggests strong demand from boards for her accumulated knowledge.
