Background

Lachy Groom grew up in Perth, Australia, built and sold three profitable internet businesses before age 18, then moved to Silicon Valley to join Stripe as one of its earliest employees (around #30), where he led Stripe Issuing and global expansion. He left Stripe in 2018 to become a full-time investor, operating as a solo GP under the LGF brand. He has raised three funds totaling over $600 million, including a $250 million third fund and a $300 million opportunity fund, backed by institutional LPs including Harvard's endowment and Horsley Bridge Partners. Beyond investing, he co-founded Physical Intelligence, an AI robotics company that raised $1.1 billion and reached a $5.6 billion valuation. His portfolio includes early bets on Figma, Notion, and Ramp before they became widely recognized.

Investment Thesis

Backs tools that developers and operators love first and monetize later, focusing on B2B SaaS, productivity, and developer infrastructure where bottom-up adoption precedes revenue.
