# Stripe Alum Lachy Groom's Physical Intelligence Crafts Silicon Valley's Hottest Robot AI
Lachy Groom, the Australian entrepreneur who built his fortune as an early Stripe employee and prolific angel investor, has pivoted to founding one of Silicon Valley's most ambitious AI robotics ventures. Physical Intelligence, co-founded by Groom in 2024, is developing general-purpose AI systems designed to bring artificial intelligence into the physical world through robots and actuated devices. The company has already secured massive funding and achieved a valuation that signals deep investor confidence in the robotics AI space.[1][2]
From Stripe Success to AI Robotics Leadership
Lachy Groom's journey to founding Physical Intelligence reflects a calculated career trajectory built on identifying transformative technologies early. As Stripe's 30th employee, Groom gained invaluable experience in scaling a fintech infrastructure company during its explosive growth phase.[1] This experience provided him with operational insights and connections that would later prove instrumental in his transition from pure investor to founder-operator.
Following his tenure at Stripe, Groom established himself as one of Silicon Valley's most successful angel investors, backing companies including Figma, Notion, and Ramp—all of which achieved billion-dollar valuations.[1] His track record of identifying breakout startups demonstrated both investment acumen and deep understanding of emerging technology trends. This combination of operational experience and investment success positioned him uniquely to recognize the opportunity in general-purpose AI for robotics.
Physical Intelligence's Funding and Valuation Milestone
Physical Intelligence has achieved remarkable financial success since its 2024 launch, raising $600 million in funding and reaching a $5.6 billion valuation.[1][2] These figures underscore investor enthusiasm for the company's mission of developing foundation models and learning algorithms for robots and physically-actuated devices.
The company's leadership team reflects deep expertise across robotics, AI research, and entrepreneurship. Beyond Groom's role as co-founder and CEO, the team includes Karol Hausman, Chelsea Finn, Sergey Levine, and Brian Ichter—scientists and engineers with substantial backgrounds in robotics and machine learning.[5] This combination of technical depth and business acumen positions Physical Intelligence to execute on its ambitious vision of bringing general-purpose AI into the physical world.
The Significance of Groom's Transition to Founder-Operator
Groom's decision to co-found Physical Intelligence rather than simply invest in the space represents a meaningful shift in his career. Returning to full-time operational roles requires substantially greater commitment than angel investing, signaling his deep conviction in the opportunity.[1] This hands-on involvement suggests Groom views Physical Intelligence as potentially his most impactful venture, surpassing even his successful angel investments.
His personal connections within Silicon Valley's elite circles have also provided advantages. Groom was a former roommate of Sam Altman, CEO of OpenAI, providing him access to influential networks and deal flow from top founder circles.[1] These relationships have likely facilitated partnerships and insights that accelerate Physical Intelligence's development trajectory.
