## Summary

Nscale, a rapidly growing U.K.-based AI data center startup, has appointed Fidji Simo to its board of directors. Simo, formerly the CEO of AGI Deployment at OpenAI and previously the head of Instacart, joins a high-profile group of executives including Sheryl Sandberg and Nick Clegg. This strategic addition comes as Nscale prepares for a potential initial public offering later this year.

The startup, founded just two years ago by Josh Payne, has seen its valuation surge due to intense market demand for AI infrastructure. According to recent reports, Nscale is seeking to raise up to $3.5 billion in the lead-up to its IPO. Payne emphasized that Simo’s experience in scaling products used by billions of users is critical for Nscale’s mission to build robust underlying systems for the AI industry.

Simo’s departure from OpenAI in July was attributed to health reasons, though she continues to advise the company part-time. Her background includes leading Instacart through its 2023 IPO and serving as head of the Facebook app at Meta. Her appointment signals Nscale’s intent to align its governance with the operational rigor required for large-scale public market performance.

## Key points

- Fidji Simo, former OpenAI and Instacart executive, joins Nscale’s board of directors.
- Nscale is reportedly raising up to $3.5 billion ahead of a planned IPO this fall.
- The board includes other prominent figures such as Sheryl Sandberg and Nick Clegg.

## Why it matters

This move signals Nscale’s readiness for public markets and underscores the critical importance of experienced leadership in scaling AI infrastructure, a key bottleneck for the industry’s continued growth.
