Bezos family office intensifies investment surge across AI and frontier tech in late 2025
Bezos Expeditions, the private investment office of Amazon founder Jeff Bezos, has emerged as one of the most active family offices in the United States during winter 2025, driving a significant wave of capital into artificial intelligence, robotics, and advanced biology ventures. Over a span of just a few days in mid-November, the family office backed multiple high-profile funding rounds, underscoring its role as a key player in the deep tech and AI investment ecosystem.
Among its recent moves, Bezos Expeditions co-led a $106 million Series B round in Profluent Bio, a biotech company leveraging generative AI to design custom proteins using natural language prompts and a proprietary dataset of over 115 billion sequences. Just days later, the family office joined a $35 million Series A round in Archetype AI, a startup developing “Physical Agents” powered by its Newton™ foundation model to turn real-world sensor data into autonomous actions across manufacturing, logistics, and infrastructure use cases. Bezos Expeditions also participated in the $600 million funding of Physical Intelligence, a new robotics AI venture aimed at building brain-like reasoning for embodied agents — with Jeff Bezos himself stepping in as co-CEO of the firm.
These investments highlight a clear strategy: positioning the Bezos family office at the forefront of the convergence between artificial intelligence, automation, and life sciences. This momentum builds on earlier activity in 2025, including involvement in Field AI’s $405 million round — also backed by Emerson Collective — where the firm is advancing AI applications for climate and agriculture technologies.
Bezos Expeditions’ prolific activity has earned it a top spot on familyofficehub.io’s list of the 10 Most Active US Family Offices in 2025, recognizing its outsized role in shaping the next generation of scientific and technological breakthroughs. Through a combination of capital, founder alignment, and domain insight, the Bezos family office is demonstrating how single-family offices can drive institutional-scale impact across transformative sectors.
