Nscale, the UK-based AI data center startup, has appointed former OpenAI executive Fidji Simo to its board, joining a roster that already includes Sheryl Sandberg, Susan Decker and Nick Clegg. The appointment comes as the two-year-old company reportedly prepares for an IPO this fall and seeks up to $3.5 billion in pre-IPO financing.
Simo left her role as CEO of AGI Deployment at OpenAI — effectively the No. 2 position at the AI lab — in July, citing health reasons, and continues to advise the company on a part-time basis. Before OpenAI, she served as chair and CEO of Instacart, leading it through its 2023 IPO, and spent more than a decade at Meta, including as head of the Facebook app. She also sits on Shopify’s board.
Nscale founder and CEO Josh Payne said in a statement 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. “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 said.
Nscale designs, builds and operates AI data centers. Founded just two years ago, its valuation has skyrocketed on the back of booming demand for AI infrastructure. Bloomberg reported last week, citing unnamed sources, that the startup is trying to raise up to $3.5 billion ahead of a planned IPO.
Analysis
Why This Matters
- The appointment signals Nscale’s preparation for a high-profile IPO, bringing IPO-experienced leadership to the board.
- AI data center demand is surging, and Nscale’s success could test investor appetite for infrastructure plays.
- Simo’s move from OpenAI to a startup board highlights the flow of top AI talent into commercial infrastructure.
Background
Nscale is part of a wave of startups building and operating AI data centers to meet the explosive demand for compute power needed to train and deploy large models. The company has grown rapidly since its founding and is positioning for a public listing that would be among the first for a pure-play AI data center operator.
Key Perspectives
Nscale: Adding Simo brings deep experience in scaling consumer platforms and navigating the public markets, which aligns with its growth ambitions.
Investors: The pre-IPO fundraising of up to $3.5B suggests strong demand, but also raises questions about the capital intensity and long-term margins of AI infrastructure.
Critics/Skeptics: The AI data center buildout requires enormous capital expenditure, and any slowdown in AI demand could leave operators with stranded assets.
What to Watch
- Completion and terms of the pre-IPO funding round.
- Timing of the IPO filing and market reception.
- Competitive dynamics as rivals like CoreWeave also pursue public listings.
