Bob McGrew, OpenAI's former research chief, has revealed Arda, a stealth startup that has raised $230 million at a $1.5 billion valuation to build AI software aimed at returning manufacturing to the United States. The round was led by Altimeter Capital, Accel and Khosla Ventures, and the company says its models are already deployed with military technology company Anduril.

Arda makes AI software that helps automate manufacturing. McGrew, who was also Palantir's product and engineering lead for over a decade, described the product as “a user interface and an agent that does for manufacturing engineers what Claude or Cursor does for programmers.”

McGrew argued that manufacturing is human-intensive, and that adapting production to a new design for a weapon or drone takes time. When a design changes, he said, retraining a human takes a day, but it takes three to six months to change the automation to reflect the new design. Arda's software, he said, allows manufacturing engineers to build assembly lines much faster.

The company is using a combination of its own proprietary models, open-source models and some frontier models. Arda's co-founders include Augustus Odena, who helped start Adept and previously worked at Google and Meta, and former Palantir engineers Alex Mark and Jakob Frick.

McGrew said robotics is next on the product roadmap, and that automating factories could help bring more manufacturing, and more jobs, to the US. If a design changes very frequently, he said, the only place to really build a product is East Asia, because it requires an army of human workers who can be retrained quickly. Building a smartphone in the US, he said, “is not taking away American jobs. That is bringing American jobs.”

Altimeter's Apoorv Agrawal, who led the funding round and previously worked with McGrew at Palantir, said manufacturing globally is a $16 trillion industry and a $3 trillion one in the US alone. “We think that Arda, and the vision that they've outlined, will continue to capture a significant portion of that. Yes, the price is steep today, but the long-term opportunity is very high,” he said.

McGrew joined OpenAI in 2017 and worked on the reasoning capabilities of early models before the launch of ChatGPT. He left in 2024 during a wave of exits that included chief technology officer Mira Murati and co-founder and chief scientist Ilya Sutskever. He said he stayed through the November 2023 episode when Sam Altman was briefly removed and then rehired, in order to ship OpenAI's reasoning product, which he called the last key breakthrough left before AGI.

Analysis

Why This Matters

  • Arda is a high-profile attempt to apply AI to physical manufacturing, and it carries a billion-dollar valuation before a public launch.
  • The company argues that flexible automation is the missing piece for bringing production of frequently changing designs back to the US.
  • The raise shows major venture firms backing the reshoring thesis as the Trump administration pushes to onshore manufacturing.

Background

Manufacturing has largely moved overseas, and McGrew argues the reason is that frequent design changes need a large, quickly retrained human workforce, which is easier to assemble in East Asia. Arda aims to change that by making automation itself quick to change. McGrew worked on reasoning in early OpenAI models before the launch of ChatGPT and left the company in 2024 alongside other senior figures. His co-founders include Augustus Odena, who helped start Adept, and former Palantir engineers Alex Mark and Jakob Frick.

Key Perspectives

Arda and its founders: Their account is that AI software for manufacturing engineers will cut the time needed to retool assembly lines from months to days, making US assembly economically viable. McGrew said building a smartphone in the US would bring American jobs, not take them away. Investors: Altimeter's Apoorv Agrawal said the global manufacturing market is worth $16 trillion, with $3 trillion in the US alone, and that Arda can capture a significant portion of it. He acknowledged the price is steep today. Critics and skeptics: The company offers no independent evidence that automated assembly lines will create net US jobs, and the only publicly disclosed deployment is with one customer, Anduril. Whether the approach transfers from defense hardware to commercial manufacturing is an open question.

What to Watch

  • Whether Arda expands beyond Anduril to commercial manufacturers and consumer electronics.
  • McGrew's stated next step into robotics, which would move the company from software toward factory hardware.
  • Whether follow-on funding arrives at a higher valuation as the company scales.
