Ex-OpenAI President McGrew Unveils Arda, Raising $232M Total at $1.5B Valuation

Arda, the manufacturing automation company founded in 2025 by former OpenAI President and VP of Research Bob McGrew, has officially launched. According to CNBC, the company is valued at 1.5 billion USD and focuses on using AI software and agents to accelerate assembly-line programming and manufacturing automation. Over the past year it refined its product with Anduril as a design partner, positioning itself to accelerate American manufacturing.

Confirmed

McGrew himself posted that the company was founded in 2025 and went public after a year of co-building with Anduril as design partner; the platform helps manufacturers design and operate manual assembly.
The company is valued at 1.5 billion USD, with investors including Accel, Altimeter, Founders Fund, Khosla Ventures, and 8VC.
Altimeter's Apoorv Saxena co-led the round.
Core product capability: automatically converting product designs into assembly plans, with real-time updates as designs change.

Unconfirmed

The funding amount differs across posts: m1 and m3 say a 160 million USD Series A, while m2 and m4 say 230 million USD raised; both point to the 1.5 billion USD valuation. The exact figure awaits official disclosure.

Why it matters

This is another landmark case of a core OpenAI executive leaving to start a company that brings frontier-model capabilities to traditional manufacturing, showing AI applications extending into physical industries.
McGrew's background and the top-tier investor lineup gave Arda a high valuation from day one, and its deep co-development with Anduril provides real-world validation in a manufacturing setting.
