Jeff Bezos’ AI startup Prometheus raised $12 billion in Series B funding on June 11, 2026, valuing the company at $41 billion and positioning it as one of the largest private AI ventures in the world. The industrial AI firm, co-led by Bezos and former Google executive Vik Bajaj, aims to build what it calls an “artificial general engineer”—software capable of automating the design and manufacturing of complex physical systems from jet engines to drug compounds.
The funding round drew backing from major institutional investors including JPMorgan Chase, Goldman Sachs, BlackRock, DST Global, and Arch Venture Partners, alongside Bezos’ personal investment. The company has grown to approximately 150 employees since its quiet launch in November 2025 with $6.2 billion in initial seed funding, bringing total capital raised to over $18 billion in less than eight months.
Prometheus represents Bezos’ return to an active operating role after stepping down as Amazon CEO in 2021. The startup focuses on “physical AI”—applying deep learning to real-world industrial processes in engineering, manufacturing, and drug design. According to TechCrunch, the company is building software capable of automating the design and manufacturing of complex physical systems, marking an ambitious effort to replace large swaths of engineering work with artificial intelligence.
The valuation reflects investor confidence in the emerging physical AI sector, which targets the automation of tasks traditionally handled by human engineers and manufacturers. Bezos has argued that AI will accelerate invention and make engineers “superhumanly productive,” framing the venture as an opportunity to rearchitect how physical objects are made across industries from aerospace to consumer electronics.
Prometheus’ rapid scaling—from $6.2 billion to $41 billion valuation in seven months—underscores the intense competition in AI infrastructure and the appetite among institutional investors for startups tackling physical-world automation. The company’s focus on manufacturing and engineering differentiates it from consumer-facing AI chatbots, targeting a sector where AI adoption could reshape industrial productivity.
