Nscale Adds OpenAI Exec Fidji Simo to Board Ahead of Potential IPO
TL;DR
- Nscale has appointed OpenAI Applications CEO Fidji Simo to its board as the UK AI cloud provider lays groundwork for a potential IPO.
- Simo brings rare public-market experience, having led Instacart through its 2023 Nasdaq IPO after a decade scaling Facebook's app and ads business.
- The move signals Nscale's push to strengthen governance, enterprise credibility, and U.S. investor ties as it scales AI data center capacity across Europe and the U.S.
Who Is Joining the Board
Nscale confirmed this week that Fidji Simo, currently CEO of Applications at OpenAI and widely seen as the company's No. 2 executive to Sam Altman, has joined its board of directors.
The London-based AI infrastructure company said Simo will advise on product strategy, go-to-market expansion, and public-company readiness as it weighs a future stock market listing. Nscale CEO and founder Josh Payne described her as an operator who has scaled consumer and enterprise platforms to global scale.
The appointment is effective immediately and makes Simo one of the highest-profile independent voices on Nscale's board.
From Instacart IPO to OpenAI's No. 2
Simo is best known in Silicon Valley and on Wall Street for taking grocery delivery platform Instacart public.
She joined Instacart as CEO in 2021 after more than a decade at Meta, where she led the Facebook app, oversaw video, news feed and advertising products, and helped grow the platform's mobile business to billions of users. At Instacart, she diversified revenue beyond delivery fees into advertising, enterprise technology and retail partnerships, steering the company to profitability ahead of its September 2023 IPO on the Nasdaq.
After stepping down from Instacart in 2025, she joined OpenAI as CEO of Applications, taking ownership of product, go-to-market and operations for ChatGPT, APIs, and new consumer and business applications. In that role she reports directly to Altman and has led OpenAI's push into enterprise agents, commerce, and platform monetization.
Why Nscale Wanted Her Now
The timing is no accident. Nscale has grown rapidly as demand for sovereign AI compute has surged, positioning itself as Europe's answer to CoreWeave and Nebius.
The company designs, builds and operates AI-ready data centers powered by thousands of Nvidia GPUs, offering full-stack cloud services for AI training and inference. Over the past 18 months it has announced major expansion projects in the UK, Norway and the U.S., struck large-scale GPU deployment partnerships, and raised more than $1 billion in equity and debt financing to fund growth.
Adding a director who has both run a newly public company and now sits at the center of OpenAI's commercial strategy gives Nscale instant credibility with public-market investors, hyperscale customers, and regulators focused on AI infrastructure.
What It Means for a Potential IPO
Nscale has not set a date or venue for a listing, but executives have openly discussed IPO readiness as a medium-term goal. Reports have pointed to a possible U.S. listing alongside consideration of London, as the UK government pushes to keep high-growth AI champions at home.
Simo's experience is directly relevant to that decision. She navigated Instacart through SEC filings, investor roadshows, post-IPO cost discipline and the transition from founder-led startup to quarterly-earnings company. For Nscale, which must convince investors it can convert capital-intensive data center buildouts into long-term, contracted cash flow, that playbook matters.
Her current role at OpenAI also underscores Nscale's strategic alignment with the foundation-model ecosystem. As model labs race to secure compute capacity, board-level ties to OpenAI could help Nscale deepen enterprise partnerships and stay ahead on product requirements for next-generation inference workloads.
The Road Ahead for Nscale
Challenges remain. The neocloud market is fiercely competitive and capital hungry, with rivals racing to lock in power, chips and enterprise contracts. An IPO would require Nscale to demonstrate clear unit economics, utilization rates, and a differentiated software layer on top of raw GPU capacity.
Still, the Simo appointment marks a clear step toward maturity. By pairing infrastructure expertise with proven consumer, advertising and AI product leadership, Nscale is signaling it wants to be more than a data center operator — it wants to be a full platform company ready for public scrutiny.
If the IPO proceeds, expect Simo to play a central role in shaping the growth story Nscale tells Wall Street: disciplined scale, enterprise trust, and AI infrastructure built for the applications era she now helps lead at OpenAI.
