British AI data-centre startup Nscale has appointed Fidji Simo to its board as it prepares for a possible initial public offering this fall. Simo brings senior operating experience from OpenAI, Instacart and Meta to a company reportedly seeking as much as $3.5 billion in new financing.
The appointment adds another recognizable technology executive to Nscale’s governance structure. Sheryl Sandberg, Susan Decker and Nick Clegg already sit on the board. The source does not disclose Simo’s committee assignments, compensation or ownership interest.
The timing makes the governance change particularly visible. Nscale is simultaneously presenting itself as an infrastructure operator, pursuing a large private financing and preparing for the reporting demands of a possible public listing. Each process will test more than the prominence of its directors.
Simo Adds Product and Public-Market Experience
Simo previously served as OpenAI’s CEO of applications and AGI deployment, effectively its second-ranking executive. She left that role in July for health reasons but continues to advise OpenAI on a part-time basis. Her time there connected frontier-model development with the work of turning AI into products and services.
Before OpenAI, Simo was chair and chief executive of Instacart. She led the grocery-delivery company through its 2023 public offering, giving her direct experience with the transition from a private technology company to a listed business. She also spent more than a decade at Meta, including a period leading the Facebook app, and remains a Shopify director.
Nscale founder and CEO Josh Payne said Simo understands how products used by billions of people affect the infrastructure beneath them. His statement frames her appointment around scale, operating discipline and financial rigor. It is a company assessment; TechCrunch does not provide an outside evaluation of the board’s effectiveness.
Nscale Is Building Toward an IPO
Founded two years ago, Nscale designs, builds and operates data centres for artificial-intelligence workloads. Demand for computing infrastructure has increased the company’s reported valuation rapidly, although the article does not state its current figure or provide financial statements.
Bloomberg reported last week that Nscale is attempting to raise up to $3.5 billion before a planned IPO. The amount, timing and final terms remain unconfirmed in the TechCrunch account. A fundraising target is not capital already committed, and an anticipated fall listing can still be delayed or abandoned.
The proposed financing would support a capital-intensive business. Data-centre developers need sites, power, cooling and computing equipment before customer workloads generate revenue. The source does not disclose Nscale’s installed capacity, contracted pipeline, debt or cash requirements, so it cannot show how far $3.5 billion would carry the buildout.
A High-Profile Board Signals Readiness, Not Completion
Adding executives with public-company, policy and platform experience can help Nscale prepare for investor scrutiny. Simo offers product and IPO experience; Sandberg and Clegg bring backgrounds from Meta; Decker adds another established technology-board presence. Their reputations may strengthen the company’s presentation to investors and partners.
Board composition does not resolve the operational questions behind a listing. Prospective investors will still need evidence about customer concentration, utilization, energy access, construction schedules and the economics of expensive AI hardware. None of those measures is included in the announcement.
Simo’s continuing advisory relationship with OpenAI may also be strategically relevant because OpenAI is a major participant in AI infrastructure demand. The source does not state that the advisory role creates a commercial relationship with Nscale, and no such connection should be inferred from the appointment alone.
The news is therefore best read as a governance step ahead of a possible transaction. Nscale has assembled a board familiar with scaling consumer platforms, navigating technology policy and operating in public markets. Whether that preparation produces a successful financing or IPO will depend on terms and business performance that remain undisclosed.
