From Perth to Silicon Valley: Lachy Groom's Remarkable Journey as Founder, Investor, and Tech Visionary

When a high-profile armed robbery targeting a San Francisco mansion garnered international headlines, the real story wasn’t about the $11 million cryptocurrency heist itself—it was about the homeowner, Lachy Groom, a 31-year-old Australian whose career accomplishments dwarf the tabloid buzz. While media outlets latched onto sensational labels like “Sam Altman’s former partner” or “robbery victim,” few bothered to examine the actual resume behind the headlines. Strip away the gossip, and you’ll discover a genuinely extraordinary entrepreneurial arc that has shaped Silicon Valley’s venture landscape.

The $11M Robbery That Overshadowed a Billion-Dollar Mind

The incident made headlines when armed robbers targeted a $4.4 million San Francisco residence, making off with approximately $11 million in Ethereum and Bitcoin, along with laptops and mobile devices. What transformed this from a typical crime story into tabloid sensation was the identity of the property owner: someone with deep ties to OpenAI’s leadership. According to property records and news reports, Lachy Groom had purchased the Dorland Street residence for $1.8 million in 2021 from the brother of the ChatGPT creator.

However, this single incident inadvertently obscured a much more compelling narrative. While the robbery made headlines for days, Lachy Groom’s actual wealth and influence stem from calculated business decisions made over the previous decade—investments that have generated multiples far exceeding $11 million. His portfolio decisions in companies like Figma and Notion alone represent life-changing returns that dwarf the cryptocurrency holdings lost in the heist.

Perth’s Teen Entrepreneur: How Early Ambition Shaped a Founder

Born and raised in Perth, Australia, Lachy Groom’s entrepreneurial instincts emerged remarkably early. His grandfather introduced him to HTML and CSS programming at age 10, sparking an obsession with code that would define his trajectory. But unlike many childhood prodigies who burn out, Groom transformed his technical skills into practical revenue engines.

Between ages 13 and 17, he founded and successfully exited three companies: PSDtoWP (web design conversion), PAGGStack.com (a development tool), and iPadCaseFinder.com (a product marketplace). His fourth venture, Cardnap, created a discount gift card marketplace—each project progressively more ambitious than the last.

His father, Geoff Groom, recalled that young Lachy had an almost instinctive business sense: walking dogs for neighbors, running lemonade stands, and constantly scanning for monetizable opportunities. The pattern was clear—this wasn’t a kid forced into coding by parents, but rather a born problem-solver who naturally gravitated toward building things people wanted.

The pivotal decision came post-high school. Rather than enrolling in a traditional university, the seventeen-year-old made a calculated assessment: Australian universities couldn’t teach him what Silicon Valley could. More pragmatically, he recognized a harsh market truth—US company valuations far exceeded those in Australia. So he did what few teenagers would: he packed his bags for San Francisco to chase the epicenter of internet innovation.

Stripe’s 30th Employee: An MBA in Building Internet-Scale Companies

In 2012, Lachy Groom joined Stripe during its hypergrowth phase. This decision proved to be less about employment and more about gaining a front-row seat to how category-defining companies scale. He wasn’t taking a random engineering job; he was becoming the 30th employee at what would become a Silicon Valley institution.

Over seven years (2012-2018), Groom progressed from growth roles to managing global business expansion and international operations. He spearheaded Stripe’s expansion strategies across Singapore, Hong Kong, and New Zealand. Eventually, he took the lead on Stripe’s card issuing division—a business that would later become critical infrastructure for the fintech ecosystem.

Working at Stripe during this era provided three irreplaceable advantages: financial security that freed him from needing investor capital, deep operational expertise in building B2B SaaS products from zero to billion-dollar scale, and entry into the “Stripe Mafia”—the network of executives and engineers who would scatter across Silicon Valley to found ventures and manage capital. This informal alumni network would later occupy significant positions across venture capital firms and startups alike.

In reality, his Stripe tenure functioned as an intensive, paid MBA in internet economics—one that most Stanford or Harvard graduates never access.

The Sniper Investor: Why Lachy Groom’s Bet-Picking Strategy Outpaced the Crowd

In 2018, Groom made the strategic shift to solo angel investing, forgoing traditional venture capital partnerships to maintain independence and conviction. His approach proved radical compared to conventional angel strategies. While most angel investors diversify by making 100 small $5,000 bets and hoping for statistical winners, Groom adopted what observers called a “sniper” methodology: when sufficiently confident, he’d deploy six-figure checks ($100,000-$500,000) with decisiveness.

His investment thesis rested on a singular principle: back tools that users will organically adopt and love, not software they’re coerced into using. This meant prioritizing bottom-up adoption curves, solving genuine workflow friction, and investing thoughtfully but meaningfully across B2B and SaaS categories.

The results speak for themselves. According to PitchBook, Groom has executed 204 investments across a 122-company portfolio, managing capital through multiple fund structures, and maintaining a reputation for exceptional hit rates and conviction-driven lead participation.

From Figma to Notion: How One Investor Spotted Unicorns Before Markets Did

The quality of Groom’s portfolio selection became undeniable through his early bets on companies that later reshaped their respective categories. Consider the mathematics:

Figma represented perhaps his most legendary allocation. Investing in the design platform’s seed round in 2018 at a $94 million valuation, Groom witnessed the company’s transformation into what would become a $20 billion acquisition target (Adobe’s bid, ultimately blocked). Following its July 2025 public listing on the NYSE, Figma’s first-day market cap reached $67.6 billion. Even at current valuations around $17.5 billion, Groom’s early-stage position delivered approximately 185x returns—the type of outcome that defines careers.

Notion, the note-taking and workspace platform, represented another defining thesis validation. As a lead investor in 2019 when the company carried an $800 million valuation, Groom watched Notion’s implied value surge to $10 billion within two years (2021). By September 2024, the company had crossed $500 million in annualized recurring revenue—a level most venture-backed companies never achieve.

His bets extended across multiple emerging infrastructure plays: Ramp, the cross-border fintech platform; Lattice, the talent management system; and numerous others. The pattern revealed an investor who could identify companies solving real problems before their categories became obvious to the broader market.

Building Robots With Brains: Physical Intelligence and the Next Internet-Scale Innovation

By 2024, having accumulated meaningful financial success from software investments, Groom’s ambitions shifted toward deeper technology. The question that animated his thinking: as artificial intelligence capabilities accelerated, where would the next internet-scale innovation occur?

His answer: bringing generalized AI into the physical world through robotics.

In March 2024, he co-founded Physical Intelligence alongside an exceptional founding team. Karol Hausman, formerly a senior research scientist at Google DeepMind and part-time Stanford professor, joined as lead technologist. Chelsea Finn, ex-Google Brain and current Stanford computer science professor, contributed deep learning expertise. Adnan Esmail, with four years at Tesla and leadership roles at defense technology firm Anduril Industries, brought hardware systems experience. Brian Ichter, another veteran of Google DeepMind and Brain, completed the founding quartet.

The mission sounded audacious: develop a universal foundational model serving as the “brain” for robotic systems—transforming robots from bolt-turning machines into adaptive, intelligent agents capable of navigating complex environments with human-like versatility. Groom positioned the company’s differentiation around developing generalizable software applicable across diverse robot hardware platforms.

Capital markets responded with remarkable speed. The seed round—completed the same month as founding—raised $70 million with participation from tier-one investors: Thrive Capital leading, alongside Khosla Ventures, Lux Capital, OpenAI, and Sequoia Capital.

The funding velocity accelerated dramatically. By November 2024, just seven months later, Physical Intelligence closed a $400 million Series A round, led by Thrive Capital and Lux Capital, with participation from Amazon founder Jeff Bezos, OpenAI, Redpoint Ventures, and Bond. That same month marked an unprecedented third funding event: a $600 million round valuing the company at $5.6 billion, with Alphabet’s growth fund CapitalG leading and existing investors Lux Capital, Thrive Capital, and Jeff Bezos recommitting their capital.

The capital velocity alone signaled something profound: market participants viewed Physical Intelligence as potentially the defining robotics infrastructure company for the AI era.

The Stripe Mafia’s Influence: How One Generation Rewired Silicon Valley

What makes Groom’s trajectory particularly significant isn’t merely individual success but rather participation in a broader ecosystem transformation. The “Stripe Mafia”—a loose network of former Stripe executives and engineers—effectively colonized Silicon Valley’s venture capital landscape and startup leadership positions. These individuals carried forward Stripe’s operational philosophy: ruthless focus on user experience, meticulous attention to unit economics, and obsession with platform scalability.

Groom represents this archetype perfectly: a former operator who transitioned into capital allocation while maintaining the founder’s mentality. His investment decisions reflect an operator’s instincts rather than a pure financial calculation—he backs companies run by people like himself, individuals determined to reshape how work gets done.

Conclusion: The Perth Kid Who Became a Silicon Valley Architect

Reduce Lachy Groom to headlines, and you miss the actual story. Yes, he appeared in tabloid coverage following the robbery. Yes, he maintained a relationship with a prominent tech leader. But these biographical footnotes obscure a far more compelling narrative: a teenager from Perth, Australia, who recognized that ambition required geographic relocation, who secured an intensive operational education at a category-defining company, who developed investment instincts sharp enough to identify Figma and Notion before they became obvious, and who’s now architecting what could become the foundational software layer for an entire industry—robotics.

His net worth, whether measured in capital deployed or returns generated, reflects not inheritance or luck but rather three decades of relentless calibration: spotting opportunities, executing with precision, and thinking several moves ahead in a landscape most participants are still comprehending. From his first website built at age 10 to founding Physical Intelligence with some of AI’s leading minds, Groom’s journey illustrates an archetype Silicon Valley still underestimates: the persistent, analytically rigorous problem-solver who consistently makes decisions that improve by an order of magnitude.
